Every video is free advice and helped me get to know my audi very well. You have also responded to me quite a bit. Some people ask for advice and dont actually want to hear your opinion. Some people dont have the ability to put wheels on lol. I appreciate being able to reference procedures from someone who knows the ins and out.

Great talk on the misfire. Extra info was interesting and thoughtful. Thanks!

I would watch videos of you answering questions any day. This is a good format for videos.

this is your best video in a while, thanks

Thanks for the great content! I worked as a lead tech in a VW/Audi dealership in Maine. I left in 2011 for a different job, and have been taking in some of your videos to catch up a little on what VW and Audi have been up to since I left. It's surprising to me how completely the character of their engines have changed. The old engines didn't know what piston damage was. The bottom ends were rock solid. The top ends were pretty good. I used to buy 1.8T Passats with slipped timing belts, replace the valves, and run them forever. Not sure how bad I want one of these direct injected jobs. Currently working on my boss's 09 Audi Cabriolet w/BWT FSI. #4 misfire, and it's a dead miss. Compression will push 100 psi for the first few strokes then seems to decrease to around 30 psi if you keep cranking and release the accumulated pressure from the gauge. I found a pitted roller on the rocker on the front #4 intake valve along with the corresponding cam lobe being chewed up. At 150k I'm recommending at least a complete head w/valves, rockers, cams. Just hoping the piston's still viable. Any thoughts you might have would be appreciated. Thanks for this channel and sharing all your hard won experience. I know what the acquisition of that experience takes.

Imma tell u now we r having a hell of a time with mt 2010 volkswagon cc 2.0 turbo. I just bought it from a lady pd cash for it and got it legal. Drove it down the road 10 miles and it started pouring smoke out the exhaust pipes. We took it apart found hose broke off inside a hose! Found fuel injectors, oxygen sensor stopped up. Now we r looking at the turbo. Seems everything is ok but were gonna put it bk on with new gaskets and wire the car back up see if it starts. Anyways i bet ive watched every1 of ur videis for guidance. YOU R A HUGE HELP!!! TY SO MUCH!

Just subscribed and find your advice very informative. I’m nearly sixty years old and I just bought an Audi A4. First time owning a European vehicle. Dodge , ford , gmc and Chevy since I was sixteen. So owning this Audi will be a challenge, but I like to do as much of my own maintenance. Looking forward too watching more of your vids. Cheers,

oil change 10 000 miles, that's a hard no on any motor especially a TSI. Quality oil every 5k and you will still have to hang a chain on it at 100k.

You should do more of these sit down and talk about whatevers

Looking good my friend

HI J , I would encourage you to do more of these types of videos, but pick questions that are more focused (ie the person asking must at least have a scan/codes) or as you stated a comp. test. Your insights , experience really come through in this type of format. You could also do, Dealer stories etc. or why you left the Dealer.

Good day, everyone. I am experiencing the problem described in this excellent video by NaptownbTuner ( you have all my appreciation for all your time invested and hard work to produce those educational videos free of charge, thank you for that). I'll do my best to keep this story as short as possible, but it's impossible... I own an Audi A5 1.8 TFSI CABD, I've had it since 2010, 180k miles, and I've fallen in love with it, but along the way I've encountered a slew of issues, including being hit by lightning, bent valves, a blown rear main seal, windows regulations, and a slew of split electric cables. The more work you do on this engine, the more you find. I'm currently experiencing miss fires on cylinder 4 on idle only, despite having 165-180 Psi on all cylinders. To date, I have removed the screen from the Cambridge, replaced the cam oil valve, replaced all of the sparkplugs, coils,injectors, intake manifold with all of the relevant valves, cleaned all of the carbon build up, replaced all of the intake line and hoses, replaced the throttle body, the rear main seal, replaced the camshaft sensor, and checked all of the electric cables from the entire engine loom through the ECM. I recently replaced the PCV valve, and the camshaft lum has some scoring marks, which is most likely the source of my problem. I do all of this work because I enjoy it, and I intend to keep this car until it becomes vintage ( not far to go,😁)

I’ve got 255k on my Audi b7 2.0t. I’ve got a stubborn misfire on cylinder 3 at start up. CEL flashing. Stops flashing after idle comes down. Using vag com I can see the misfire counter stop as soon as get on the throttle. Changed the plugs coil and even replaced the plug harness. Only one thing left to do….. injector time, thanks for sharing your knowledge.

I agree. Confirm that the engine is mechanically sound before throwing parts at it. Also, I think anything over 5k OCI is asking for trouble (especially for turbo/GDI systems).

Great info, thx!!

i have a benz clk 200 2.0 .i have missfire in intake...at cold start at the iddle pops hard and at cylinder 4 the exhaust glows cherry red....replaced coils ,spark plugs,watched in the dark for sparks on wires but it is ok......car runs fine but when after engine brake and accelerate again it pops for few seconds but it runs fine after

i get that problem too , now its solved but was spark plug ceramics bad and turbo waste gate and diverter valve .... cleaning intake valve too !

I have Tiguan with 2.0 TFSI engine. Driving on highway injector blow up and got stuck in open position. Drove home for about 10 minutes, had some white smoke coming out exhaust. My question is, how likely that there is catalytic converter damage from fuel coming out and should I change engine oil as well? Thanks

Naptown, any updates on a build you mentioned about a year ago?

Hey Naptown Tuner. You have good advice and a wealth of knowledge when it comes to Audi/VW stuff. Scotty Kilmer offers free advice on stuff and I tried it and was extremely disappointed in the brush off comments he made. It costs a lot to create and app, but it probably only costs $500 to setup a website. Not sure how much KZfaq $$$ you make per month. But with your experience you should really consider starting a website and let paying customers ask you for advice for $25 or $50 a pop. You can list your answers on the site or make them go dark if the answer is paid - up to you. But might be able to gross an extra $500 or more per day in your pocket giving solid answers to questions with paying customers. Imagine making an extra $10K or more per month. I think your worth paid advice. Don't you?

Thank you

Good way to tell if it's a stuck open injector, is to pull the spark plug and look for fuel on the plug.

My man!

Great breakdown. So what is ball park to do a complete rebuild of this engine? 5k? 10?

Ok guys I've got the same problem, misfire cylinder number 1, replaced plugs, coils, injectors, compression test, de-carbed the valves. The car misfire on start up brings up the EPC light soon as it gets to operating temp it runs fine no issues, would I be right in saying it might be the coolant temp sensor for the ECU?

Could it be damage to the coil wiring harness? Maybe the clip is broken and not making good contact with the coil. I’d compression test first. Then look electrical.

I have a 2013 Audi a6 3.0t supercharged and I’m having misfires on bank 1 cylinders 4,5,6 have any ideas ?

Hi there, I need some help and I've seen your content and I think you could possibly help me. I have we a 2015 audi a6 2.0t. I have misfire on 1,2 and 4. I took off the coil and has oil in chamber in all 4. I can only assume it's gaskets but not to sure.

Is driving 800 miles with bad pcv valve possible?

when engine reaches normal operating temperature .......you have a very small droplets of coolant going into your cylinder chamber causing a misfire, ........ a video cam would help,

Hey bub im from indianapolis Indiana do you have a shop, cadillac cts 05 running rough

Im the unlucky one stuck with this mystery idle 2.0T ecu doesnt even pick it the misfires they only occure sligtly on idle car doesnt idle dead smooth as they should. When i take off its all smooth. tranny does shift a bit early and you feel the little bump nudge forward at every shift(AT)

Chasing misfires came down to find oil on plugs can you list causes.. turbo failing? Valve guides.? What about the oil separator on intake,

Change oil sensors

I'm dying to know where you were "babysitting" 1000 2.0T's. Was this a fleet of cars? Rentals? I can't even imagine. MERRY CHRISTMAS! Moving to Arizona but I WILL BRING MY CAR TO DETROIT and LEAVE IT if ever I get to the point that I have to have pistons.

Had same issues in cylinder 4 also Cleaned intake valves,injectors and air intake and new plugs Coil packs replaced New bore scope camera Found burnt valves and a piece missing from the valve and cylinder wall damage Found burnt valve

if all OK...ECU must be corroded...need to clean or change new ECU

I’ve had issues with 2011 audi a4 2.0l avant for almost a year. Rough idle, white exhaust smoke, sputtering, shaking, acceleration issues. Put around $8k into it 6 different mechanics. New engine, oil filter housing gasket, Spark plugs, Pcv valve, lower+ upper control arms, tie rods, cabin, oil, air filters, getting p0304 misfire cylinder 4. Just had oil changed it was at max removed .5liter of oil now just under max. Running better. Spark plugs were just put in. Ran good for 700 miles after the Pcv valve replaced. Then oil change back to rough idle. Dumping money into it. Still issues. Any help would be much appreciated almost ready to give up got $500 more to put into it. Thinking injectors or coils. It’s also shown rich idle before Pcv valve.

Do the injectors have to be coded to the PCM and were they?

Just because you replace a coil will not mean it is a good coil, i agree with a coil swap and a plug swap

No way!! I’m doing this job on Wednesday to my 16 a4 flex fuel. Misfire on every cylinder tons of codes. Going to use your expertise to remove everything & put it back together. Fingers crossed it’s the injector. Strange thing though. The misfire happened 5 minutes after I filled up with E85. I’m hoping it’s the injector or injectors. I’m going to replace all four. Then change the oil, coil packs, spark plugs, air filters. I really hope this helps. Sounds like my exact issue. I have an epc light on & flashing engine light. I change my oil every 3k miles consistently.

all boil down to ECU malfunction

I am currently in the same boat......i replaced, spark plugs, ignition coils, fuel injectors, replaced rear main seal, pcv......car smells like it is burning rich.....a little bit of white smoke coming out.....rear main was damaged, replaced injectors because gas was coming out of tail pipe. I am getting misfire in cylinder 1 and hide cylinder. Checked compression and it is 150......At this point not sure what to check/change next.....i did an intake valve carbon cleaning when i replaced the injectors......I am getting EPC light and check engine with code P0301 for cylinder 1 misfire....car is currently not driveable......car is a 2010 Audi A3 2.0TFSI Quattro with 68K.......any thoughts anyone?

Fun fact just take it to audi ik its expensive but na bro these cars are for people with money neverr everrrrr mess with the harness sadly im 18 and learned the hard way and had to pay 4k

why my audi a3 cylinder 4 misfire spark plug wet with fuel

1.8 t

This is what happens when you go cheap and try to outsmart someone with 50k+ invested in his career. Not including blood sweat and tears. Well deserved 👏 keep throwing parts making big parts companies money and working class poor.
