I have the check engine light, battery and EPC lights stay on when I turn the key half way but when I switch the engine on and let it idle they turn off. Is that a serious issue?

Glad to see people sharing the tips. Almost 100 000 views!

My pleasure to help. You can have a repair bill from $500 to $3000 . I spoke with a service advisor about it.

Wow I never knew the epc light comes on for the water pump. Thanks for commenting and contributing so we all learn. Thumbs up.

To do with brake light fuse fixed it today working fine 👍

My pleasure. Hope you get back on the road fast. I also included the video how much is the fix EPC light when injectors go bad so people can take it seriously.

Wish everyone luck on repairs.

Over the years, we changed two throttle body replacements, two throttle body plug replacements, we finally replaced the entire engine wiring harness. Fixed. The only thing left was the ECU. Wiring harness is $800 plus labor, $1400.

When I try to start my 2009 audi a4 2.0t the throttle body starts ticking so I took it out and seen that it smelled like gas so would that cause the car to not start if the sensor on the throttle body senses that the gas is pushed in then it's not and turn of the fuel pump?

There are the times where these cars are very tricky to diagnose, snd that is why the Audi / VW dealers charge the premium to fix these cars. That is why I made this video to help the people as much as I can.

Michael thanks for the comments.

Spot on about autozone .

I would advise you to check it out because the repairs on the EPC are very costly. At least you know what you are in for it.

North, I would get someone to diagnose it more specifically so you don't end up throwing parts at it. I am not sure if you can clean injectors as theyv tend to fail .

Nice job. Makes alot of sense to just replace the whole assembly instead of diagnosing a spicific part. Thanks for the heads up

Btw If any of you are experiencing jerking or weak acceleration, that is fuel related. Your injectors are compromised. If you are getting bad fuel mileage, it is 99% a fuel injector going bad. You will need a proper diagnosis to know which one it is.

Fingers crossed for inexpensive outcome.

Thank you, been trying to figure out what the problem is with the EPC. Very well explained!

My EPC light was on we fixed the trottle body and also in tank fuel pump I drove and now it came back on

Thank you!

Hello there, i have a 2012 vw golf. Im having weak power issues/ hard idle and throttle. I pulled the code and it says cyclinder 3 misfire. I tried replacing all the coils and spark plugs. The epc light come on then dissapears. Thank you for this video. Im hoping its the throttle body.

Thank you so much for this❤

When my EPC light comes on while driving, I simply put Passat in neutral and turn ignition Off, then back On. Light goes away and Passat drives great for another 200+ miles until I have to do it again. Mechanic charged me $1600 and could not fix the issue after replacing several parts. Not sure what the problem is exactly, but this has been working for me for 4 years and 120K miles on 2016 Passat.

Bought a used 2013 Jetta gli I didn’t know it needed premium and put regular gas after a few miles of driving check engine light came on and epc too. Does it have to do with the gas?

Hi my car a 2015 VW Jetta epc is on and sometimes it jerks and the acceleration is bad it takes a while to get to speed. Also when this happens, my car takes a few times to turn on. It keeps clinging until it finally turns on and then the light shows up. I check my cars codes and I got the P0236, p1020F00, and p065800.

I have VW GTI MK7 stage 1 remap. I recently, a month ago, had a new clutch as I burnt out my Sachs paddle clutch racing it too hard. Then this week EPC and engine light came on, problem with throttle/power driving. I turned the engine off and back on, lights gone, drove it cautiously. Put my foot down a little and EPC light came back on its own, throttle issue was worse. Limped home. Went to garage and computer said coil pack issue. The garage ordered spark plugs and coil packs. They put in new spark plugs but said the coils were fine so didn’t change them. The car drove ok for about 20 miles, then throttle issue again going up a steep hill, but no light on. I then parked as it was by my house. Any ideas what it could be?

I only got a epc light when I went full throttle on the highway. Then the car went into limp mode. What do you think it could be?

2015 audi a4 2LT. I replace spark plug n coil packs but still saying epc and check engine light. Can only assume it the low pressure fuel pump or the fuel injectors. After replacing spark plugs n coil packs. Cylinder 2 is still miss firing. Injectors???? Please help

2012 Passat 2.5 with CEL and EPC lights on. Autozone scan shows P0122. Removed throttle body and cleaned it but lights stayed on and still have loss of power issue. Going to buy a new throttle body and replace. Hopefully this fixes it.

Thank you

Hey thanks for the video. So before I watched this, I took it to a VW Dealership because my wife's 2014 Jetta GLI keeps getting the EPC light on and off, it doesn't turn on when you go into sport mode though. Anyway, I paid for Diagnostics, and they came back saying the following, "Caused by: run gff found fault for p00af boost control "a" module performance. Found faulty wastegate module sticking causing fault, need new turbo. $3884 parts and labor." Anything you can share with me that might help?

I have an 07 GTI. when driving randomly It’ll surge lose all power epc light and stability light will turn on. Check engine light sometimes comes on in unison. Restarting fixes the power issue but the lights will stay illuminated for a bit. Had the throttle body wiring replaced and the throttle body as well.

i have a 2020 volkswagen atlas cross sport and when i turn the car on the engine has some time to start then it starts and then i get some jerks and i can’t fully press down the accelerator it doesn’t go

Hello i have an 2016 audi a3 1.8t and my epc light has been on for a while now i noticed it came on after i installed some performance parts i did feel the cars power not fully 100% at first but it does the job still no check engine light has ever came on i installed and coil grounding kit and still the epc light is on i also reset the pedal sensor still nothing i disconnected some wires and cleaned them up on the engine and noticed an increase in acceleration and performance like if theres nothing wrong with it but that pesky epc light is still on i plugged in an code reader and all i got was low boost but the car feels magnificent would low boost cause the epc light to be on also im planning on cleaning the solenoid/s on the vehicle and replacing the camshaft magnet positioner hopefully that solves the problem i do need some feedback please reply what do you think may be the cause?

I have a 2019 VW Golf and I just took a pretty big trip about 2k miles since I moved states. I had a big pay load and used the cruise control most of the way there. I’ve seen no noticeable problems other than the EPC light suddenly turning on and my start stop button pops up an error when using. Still Not sure what’s wrong with the car.

Thank you so much for narrating this yourself. (So many people are using the shitty AI robot narration and your video is way easier to watch). Great info - straight forward

Josh, that seems fuel and throttle body related. You have a fuel issue as possible bad fuel injector or a manifold. Based on your experience, you must have codes stored by now. Get the car scanned by a parts store and read the codes on Google, than look at your options. Wish you luck as that is a nice motor in it.

I have a 2012 VW Jetta se 2.5 with codes P0122 P0222 throttle pedal position low input and code 01314 DTC any help thx

so i have a 2009 audi a4, when i was driving the engine light started flashing and epc light came on. the car started shaking also, it still runs and drives, but i dont want to mess anything anymore so i stopped driving. i just changed the spark plugs and the coil pack looked fine, but there is a ticking noise around the turbo area, anyone know what it could be?

The EPC light intermittently stays lit when I start the car. If I turn the car off and back on it doesn’t reoccur. For the first time yesterday it came on while driving through a sharp curve at about 30 mph. I stopped the car and turned the car off the back on. The light did not return. My mechanic said code indicates the car needs a new turbo waste gate for $2500 parts and labor. The intermittent recurrences baffle me. Any thoughts before I go ahead with this costly repair are appreciated. Thanks

I have an issue with my EPC and traction control light coming on intermittently on my VW Jetta GLI 2.8 VR6. When the EPC light comes on at first, I notice a SLIGHT uptick in my RPMS. For example, when I am idling around 700, it might increase to 8-900 immediately when that EPC light comes on along with the traction control. I also notice I have a very, very intermittent issue on the highway when I suddenly have no throttle response, then it comes back like the car is surging, then no response again, and either my car appears to go into limp mode where if I throw it into neutral, the RPMs go to zero and my battery light comes on, or if I keep my foot on the gas for long enough, it will come back to life (half the time). Please let me know if you think this is a throttle body issue or something else if you can. Subbed! :)

hello Ivan: I have Tiguan 2010 2.0 TSI, In good shape.I am drive that EPC and CHECK ENGINE Show up om Dashboard and The Engine Went OFF.I turn engine on is working fine for couple minute.If i drive on high way is working fine,EPC and CHECK ENGINE ON is when i am on heavy trafic.I scanning and show me this message/ECM POWER/PERFORMANCE RELAY CHARGING CIRCUIT DE-ENERGIZED TOO EARLY, THANKS FOR YOU HELP

I have the throttle body from Amazon and it now it throws up the epc light when I step on the gas a little too fast. Is there anyway to tell my vw to like it (mk6 gti)

Hey man not sure if you can help, but I have been having issues with my car recently. I have a 2015 VW GTI with an EPC light on and a few codes P0045, P00AF, P2563 and my car didn’t build any boost. I brought it to a VW dealer and they said it’s most likely the wastegate failed. So I replaced the factory IS20 with an IHI IS38 (Factory Golf R Turbo) the epc light went away and my car was driving how it should be, building boost after 3k rpm. I did a pull one time and the epc light came back on with P0045 and P00AF codes. It drives perfectly fine just doesn’t build much boost, only 10psi when it should be closer to 29 psi. I’ve brought it to another vw dealer, paid the diagnostic fee and they basically told me they can’t figure out what’s wrong with it. I just want my car to drive how it normally does and I want the epc light gone so I know the car isn’t being damaged every time I drive it.

For new comers...i have this problem with my 12 sel premium. If you car doesnt accelerate pass 60mph n is jerking it is the high pressure fuel pump under the hood. Fuel injector clean might work a couple times but your car will get immune to it. The pump is 250 online its easy enough that if your handy with tools you can change it yourself hope this helps anyone....i did some digging digging for this info so thank me later Ps the part is called direct injection high-pressure fuel pump as most vw have 2 fuel pumps the d.i high pressure fuel pump under the hood and the actual fuel pump assembly located near the gas tank

Hi I have an Audi A5 2013 the Epc light comes on only when i don’t fully turn on my car, when I press the push to start without the brake then it disappears when I push the break and the push to start

i havw a 2008 audi a6 3.2 and it gets it and the car starts to shake and after 10 minutes it runs good

Hi will the epc light come on with other fault codes? Bc I've scanned and no codes come up. Only the ecp light.

My EPC light turned on and my car accelerates and deaccelerates in park. I haven’t scanned it yet but I will soon. What do you think?

Recently there was engine oil leakage in our A4 audi.we fixed it.after the dealer fixed it the epc issue has popped up. The epc light gets on and the car jerks very badly . Any advice on wat happened ?

If the genuine $537 Volkswagen part failed, maybe its better to go with another brand $57 which will probably work better and the $537 part will probably keep failing anyway.

I have a 2015 Audi A6 2.0 T less than 80k on the miles had the top off oil light on dash… topped off oil soon after restarted car shut itself off and hasn’t started since I have now check engine light and epc showing on dash… any help is appreciated as far as codes from scans I got p052c but I’ve seen this code prior to car not starting and this is the new code I’m getting p305400 p0c55

Please help me with my Audi A4 2009 AC compressor issues

I just brought my 2016 GTI in for an oil change a few weeks ago. Everything was fine other than a slight alignment issue. Tonight, as i was driving on the highway, I noticed EPC light come on. Never had an issue before. I just feel like they made this happen so I’d have to go back in and spend more money. I’m crazy, right?

Swapped out throttle body 2016 jetta and car runs fine, but after driving for a little epc light comes back on and it’s showin code p2263 and car has hesitation

I have an epc light and check engine light on my 2015 Audi a3 1.8t, the pedal barely accelerates even when floored and my loud intake makes no turbo noise. Plz HELP!

I just had a diagnostic done and nothing came back in the rac side just a bulb the light has gone out what could this be please It was about 29 degrees yesterday when it happend

Hi. My EPC and battery light goes on when i turn the key but not the ignition. It goes off when i start the car. Its a vw polo 1.4... is it something to be concerned about?!

Hey I’m looking to buy a 2015 golf gti with 47,000km with the epc light on, should I buy ?

Was changing out the air filter on my '17 jetta 1.4t tsi and someone stole my compression clamp pliers used for the intake hoses.... lol sooo i put on what i could without them taking off into space and just snug fit the rest on the intakes... I drive 7 miles into town to get conventional hose clamps (because i'm not spending $40 for a pair of those damn things again) made like 2 other stops to look for a fuel filter and finally after the second stop, i pull out onto the road and didn't even accelerate that much and IMMEDIATELY popped that EPC light, soooo i limped it directly across the street (from orielys to auto zone) and put on the worm drive clamps.... It turned off lmao just amazing how something so small can pop that code!! just like a gas cap in my MK3 jetta triggers the CEL. on a side note, the kid at orielys told me that the fuel filter WAS NON SERVICABLE LIKE WTFFF AINT NO WAY HOMIE LMAOO I CAN LITTERALLY TOUCH IT!!! LIKE WTF.

Hi The epc light on my 2010 audi s4 turned on and the car started shaking does anyone know what it could be

my 2012 passat 2.5 has a problem with the epc light. it first started when i was driving on the interstate and my engine cut out. my steering wheel locked and after i turned the car off and waited a couple of min, the car turned on and i got it off of the interstate. after letting it rest for an hour, i went to turn the car on and it wouldn’t start at all. i took it to the vw dealership and a local mechanic who specialized in euro cars and they both said it was because of an oil leak i had. i got the oil leak fixed and the car worked fine for a day and then the epc came on again and it hasn’t started since. i have no idea what the issue is

Can a low battery cause a epc? I used a scan tool but no codes . I do have a faulty alternator and my Audi displays a faulty alternator battery not being charged on the dash.

I have a 2014 Passat 1.8 gas, SE TSI. When I accelerate hard, EPC light comes on along with stability light and tire pressure light, car goes into limp mode. If I turn off and restart car, they all go off except the check engine and the car runs fine. Only if I accelerate hard or sometimes when I go up a hill. Had codes scanned and o2 sensors came up, replaced those,and evap...not sure what part to replace for that. Any advice would be great.

Mine just did this driving it 150 in the 110 degree heat. Its the throttle positioning sensor most likely. It will blow the s3nsor and put car into epc mode. Im waiting for car to cool right now to try to reset sensor

Thinks 👍

Hey guys, I have an Audi A3 2016. When I turned on my car, it didn’t start straight away but I started driving on my EPC light turned on. When I started driving, I had 3/4 of a fuel tank and by the time I nearly got home. I had no fuel left in my tank and there was a lot of fuel fumes entering the cabin. The car van completely died on me. It sure what to do.

Por FAVOR podrá darme información en español saludos

Hello I have a VW 2015 Golf ! I got it scanned but nothing came up and I still have the EPC ! My mechanic recommended me to change the turbo but also told me that I can drive it without having to worry about it. What should I do ? Also my cruise control doesn’t work due to the EPC ! Please help

Hi which part of Canada do you live

VW 2.0 getting battery, EPC and engine light on. replaced the throttle body. Not sure what's causing the problem.

Hi! I have a 2016 Audi A3 and for the past few months, at random times, my car is very sluggish when I try to start it and then shakes until it is fully started. The EPC light comes on then goes off. It’s been happening more frequently lately.. I’ve had all spark plugs and coils replaced. No codes still. Would this be a fuel injector problem?

Great video. I will follow your advice!

Hello, my EPC light comes on in my audi A4 then if i drive the car for like 100 metres, then switch it off and start again it doesn't pop, what might be the cause?

Hello can someone help me, I have a Volkswagen Passat sel and I have the epc and engine light, abs, and traction control on, I changed the throttle body and it worked but after 2 days those lights came back.. so I’m not sure what it is

Hey man I have a Audi A6 and my epc light comes on with my cruise control some days it stays on some day it’s off I got tests ran on it they told me it could be my wiring

My gti 1.8 swapped 2.0 was running fine til I shifted and the car just stop running while on . Battery died had to jump it then found out the coolant was dry so I got some coolant then turned car on started making knocking noises but no smell couldn’t tell if it was a valve or a rod or something else heard from on top of motor or under couldn’t tell. After that car wouldn’t go over 5 mph anyone have any ideas? The car starts up fine now but I can’t drive it until fixed. Kept overheating as well maybe spark plugs or coils no idea

I have a 2012 Audi A7 and my epc light comes on. It shows a p133500 code. Please help Car is tuned stage 2+

Dang .. I had a broken rubber hose that connected to the engine and air intake . It was making like a weazy sound and pulsing. Could that make the EPC light turn on ? I only have an EPC light and no check engine . I replaced the broken hose . But light is still on . Will ut go away or i have to clear it and see if it comes back? Thank you for any help!

OBD codes arent always helpful. It gives you a list of potential issues on different parts, but it doesnt narrow it down. Mechanics will say, well one can be throwing off another thing and you start replacing things that dont need to be replaced and end up costing you the same as taking it to the shop.

I've got ESC message on my dash, any idea why that is and how to fix it?

Hi there, Thank you very much for making a helpful video! I just have a quick question and was wondering if I could get your tip on my situation. So, I have a 2014 Volkswagen Passat 1.8 SE, and It is having a couple of issues right now. It all started a couple months ago, the engine just sometimes turns off when I sometimes go full stop and the battery lights come on. So I thought It was the battery issue and replaced it and it still does it again on some cases :( Another issue I would like to ask is the EPC light. Back in the day, I was accelerating hard and the EPC light, engine light, and tire pressure light came so I got freaked out. So, I immediately went to the dealership and they replaced spark plugs and it happened to disappear for a while. Well.. it is still happening on some occasions. (The EPC light goes away when re-ignition tho) and now I am also getting the weird noise with high and Unusual RPM when making a corner/turn with hard accelerating. I am super frustrated with these issues and kind of afraid to take my car to the dealership when they are gonna charge me $$$. I was wondering if you could give me any advice on this matter. Thank you very much for taking the time to read my comment and I hope you have a great day!

Get someone to come over to scan before you pay a dealer $150.

Hi, I got my vw gti mk7 eqt stage 2 tuned diagnosed at the dealership and they say it is a circuit problem and they can’t do anything to car because the tune voids the warranty. My car has weak acceleration and going into first gear is very easy to stall. Anyone have this problem before?

I av a vw mk5 golf,this light is staying on ive changed the rack senser etc still on,the car is remapped 1 is that the problem?does it need resetting?bk to factory

My w/v Passat 2007 2.0 light on epc in car turn off and never start again?

Just came home from 1 hour drive, i noticed that EPC error show up on dashboard, then *engine fault check workshop « note pops up, i have a Passat Volkswagen 2009 2.0 TSI In good shape, service just done , in traffic light 🚦the engine went off suddenly after showing error EPC. When i started the engine it worked pretty well, then the error disappeared. However after 15 mn same thing happened again. Could you please explain to me

I have a polo 1.2 tsi and my EPC comes on daily yet nothing happens to my car I don't lose power or anything the car drives as normal so not sure what it can be?

I just watched video that guy indicated to fix his epc light was his ECU module. If the throttle body is failing then how is it an ecu issue ?????

I replaced throttle body. but driving 80miles after pop up EPC light. anyway Thanks

My epc light came on earlier in my Jetta, only that light came on, then I turned off, then back on and it’s not come on again since. Has this happened to anyone before

My Audi A3 Has the EPC and check engine light on and will not accelerate past 40 mph

Please also Do NOT ignore EPC light.

I have a 2009 a4 2.0t the epc light is on and it tells me parking break malfunction even tho it works and the car wont start

So this video isn't necessarily how to fix an EPC light. The title seems a bit misleading but I'm betting all those views have netted a few bucks. I digress. To summarize the video: 1. Scan your car for codes. 2. Research parts related to the code, and search for the cheapest possible price for the part. 3. Replace the part and hope it fixes the issue. 4. Return the part if it doesn't fix the issue. Full disclosure, I hate stealerships as much as the next guy, so unless there's a recall, I avoid dealer service departments like the plague and only use reputable independent shops if I can't fix something myself. Not to bag on this guy, and I appreciate that he seems to be trying to help people avoid costly dealer repairs, but what's being suggested in the video just isn't sound advice. The problem is, simply buying the cheapest-priced part can be seriously risky. There is no end to all the cheap Chinese parts available on Amazon, etc., that might not only end up being defective, but could potentially damage your vehicle. I replaced leaky power steering hoses on my truck with parts that were less than half the price of the factory parts. Guess what? Less than two years later, both hoses are leaking again. So now I get to spend more money to buy quality parts this time, and at least 3 hours to replace them. Thankfully I caught the leak in time before my power steering pump and steering gear were ruined. Second, the suggestion that you can just throw a cheap throttle body on your car -- and if it doesn't fix it, you can just return it -- is simply terrible advice. I have never known a parts store to allow a return on a used fuel-related component (or electrical component, for that matter) unless it is defective. Amazon may be the exception to that, but then again it's probably not the best idea to ship anything that has had fuel in it anyway. I don't think the postal service or any other shipping company would appreciate that. Bottom line: 1. Get your car scanned and thoroughly research the code(s), then research how to actually test potentially faulty components rather than just start throwing parts at your car. Shooting the parts cannon is neither an efficient nor cost-effective substitute for basic troubleshooting. 2. Don't be fooled into thinking any cheap part is going to work. You could be out more money -- and time -- in the long run by using inferior parts. Check user reviews and ratings before purchasing an aftermarket part. I'm not implying this is always the case, but sometimes factory parts might just be the best option, even if they are more expensive.
