I dunno who this may help but I have a tip. I had been struggling with "check coolant" warning, intermittent, went away after restart sometimes, would come on very sporadically. Coolant level was always fine. Having replaced waterpump and thermo a few times, I thought here we go again. Fortunately temp gauge wasn't fluctuating. So here is the tip that saved me recently. CHECK THE SENSOR ON THE COOLANT RESERVOIR. Make sure the two pins are actually contacting firmly and have no play. Otherwise while driving if they lose contact, it throws the warning immediately. 2015 MK7 GTI (south african spec)

Very important to make sure to check the low level sensor installed in the reservoir tank. It will save a lot of headaches in the long run. Thanks for mentioning it Paul.

Did anyone else notice the coolant leaking out of the reservoir in the video? A pretty steady drip drip right under the reservoir after you filled it

Now that we know a little more about MK7 common issues, it’s funny watching this video knowing the car probably wasn’t just “burning off” the coolant (not Paul’s words of course). Luckily when my thermostat housing failed, the car was still under warranty. Thanks DAP for keeping the videos going!

Thank you! Managed to avoid a coolant mishap on my Q5 road trip. Saw the low coolant in the reservoir, added some water in the mountains where G13 wasn't available. Thanks again! No more coolant light, and no overheating was evident thankfully! You’re a godsend at 1:30am lol

This is really informative! Thanks Paul. One note I didn't see is MK7 EA888 cars have coolant circulation after shut-off to cool off the turbo and other components. If you hear the pump going (5-15 minutes after shutdown), this means the coolant level isn't accurate as it's still circulating. I usually check coolant when car is completely cold.

Apparently bad temp sensors or bad battery can trigger those messages, i. e. my VW Touareg V8 4.2 kicks engine overheating message just after i start the car in winter (which is impossible engine is stone cold ~30F it would take some time for it to warm up, temp gauge on the dash acts perfectly like it should in accordance with my estimated engine temp) so check coolant temp sensors and check your battery, mine did not complain after i charged battery which was bit low, i do have temp sensors ready just in case...

Thank you this is very useful for my brand new VW. I was just curious if my water was still fine on my engine but now i know i will see the red light when the coolant runs out

Interesting you guys posted this video now. I just got my 2015 GTI back from the dealership regarding a coolant leak last week.

thanks for the video, I was traveling and the alert just appeared out of nowhere. It was a low-level alert, and just by opening the reservoir and releasing the pressure, the level returned to its optimal point.

Thank you for your video. We are road tripping and this light came on. Checked it and damn its low. Most especially thank you for saving me from buying what I can get at the gas station in the middle of no where because I would have done just that. We added some water (no freezing risk) and are going to our destination. We will be getting a coolant check when we get there.

6:23 I think I found your leak

These vehicles have a tea bag thing in the coolant reservoir. If you can get it out carefully, you should. That thing fails, its bye bye heater matrix. It carries silicates supposed to prolong the life of the coolant up to 5 years. I think I would rather just renew the coolant after a couple of years, rather than risk serious expensive damage.

had the coolant light come on for me and it was because I had TOO MUCH coolant. this video helped thanks!

Funnily enough Had this light coming up in my mk7 gti like 5 days ago The sound the warning made... it made me shit my pants. Made me think that the engine blew up or something! Especially when it came up right after a low tire pressure warning

I've been driving for 5 years without coolent just water now all my wells plugs are leaking water, goodness I had no idea there had to be coolent in I thought it was optional, I'm driving a polo playa 1.6 ,2002 model

Would the car generally burn coolant so the level would drop slightly over time?

Thanks so much for your advice. I applied it this morning & bought myself some time by topping up with water until I get my hands on coolant today. I hope I can get the right brand in my country.

I brought some coolant for my daughter Volkswagen jetta yesterday. He was the green coolant. The lady at AutoZone look up in the computer💻on seeing the right one I should buy, but she wasn't still sure.Glad I watched this video here, her vehicle uses the pink color.Ima still pop her hood on checking being on the safe side.Ty👍

It’s critical to NOT use any of those this works with any type coolants. It really doesn’t work in our cars and can harm the system. I keep some G13 in my trunk now just in case. If I can’t get to that it’s distilled water. Deionized water is even better but not as easily found.

What to do when coolant light comes on - clear it with OBD11 😂

My 2009 GTI has been slowly using coolant, the warranty was recently extended on my water pump. Local VW guy said it's not a problem if there's not a leak. Well maybe that explains my mystery of the missing coolant. Wish me luck dealing with these guys 😐

Hey man.. THANK you for this perfect.. short-n-direct video that PERFECTLY explained what just happened with my 2012 Passat. Thank you! Got a 👍🏾👍🏾 from me

Could you share a video how to get rid of air from the coolant system / how to do a proper coolant flush as to where are the nips location to release the coolant from the system and fill up. Thankyou so much

Do you need to drain the hole system first before adding more coolant?

I just read my VW Tiguan manual when the cooling system warning light began flashing. Not to dispute anything here, but the manual called for mixing DISTILLED water with the coolant. Maybe model specific (2012 model) that is outdated, but can't hurt to check the manual first.

What happened to the coolant? Did the car burn it or do you have a leak?

This literally happened to me yesterday! Luckily I work at an auto shop. I did a coolant pressure test, and refilled my resivoir which was low.

I have a huge problem. It all started with a leak around my heater hoses with Caked Up antifreeze around it. I replaced the heater hoses about 6 months before that I replaced the radiator. I have a 2006 2.5 5 cylinder Volkswagen Beetle. After I replace the heater hose the red thermostat light kept coming on. The next thing that happened was the fitting at the top of the new radiator cracked so I had to replace it again. It ran all of the day then the red thermostat light came on again and several more hoses busted one at a time. I replaced those. I drove home the light turned on again and I let it idle for about 10 minutes then Bang fluid was coming out from everywhere but I didn't know what was the source of the problem. I finally found it and it was the thermostat housing it cracked and had a hole in it about a size of a quarter. I've since replaced that I drove it all of 10 minutes and it's leaking everywhere again. After each replacement I don't run any freeze through it because it's quite expensive.. I'll add a little antifreeze and let it run to see what happens I have to take it apart again but do you have any suggestions of where I should look or what my problem could be?

Summer 2022, this video popped up on my KZfaq feed. So I went and checked my coolant levels. Sure enough, its BELOW minimum. GOOD TIMING KZfaq algorithm

When will that jacket be available for purchase? That's the most serious question here

Happening on my b9 s4, still waiting on the parts but local garage says its safe to drive. Very helpful!

The o-ring for the temp sensor on the 2.5l is a weak point for leaks. It eventually drains out on the passenger side, looking like a bad water pump. Check at the same time as when you are checking the vacuum pump that leaks oil looking like a main seal failure

Should you be using distilled water? Or if your in a jam and the gas station has no coolant or the wrong type of coolant, should you use bottled water then? Say this happens during the summer.

I was told that the coolant is to concentrated so I took some out and added distilled water and the light went away the next cold start. It's now at -25° C (-13° F).

My coolant light came on on my B8.5 A4 and the coolant level was fine. The dealer said they’ve found corrosion on the terminals that triggered the light

What are those drips at the bottom of the coolant over flow tank at 6:28?

I check mine regulatory, is it normal to lose some over the course of several months? MK7 Gen3 EA888.

Two questions. Is coolant corrosive, i.e. if I spill some, should I immediately clean it up or just let it hang out? Also, I don't mix mine 50/50. I just put straight G13 in. Is this an issue or am I just costing myself money by not diluting it? Our temps top out around 75F but we regularly see -20 to -25F.

If the light comes on but the level is correct, take an OLD toothbrush and brush the sensor in the bottle. This helped my 2001 A3 and I never got the warning light (especially in winter) again.

The VW is my wife's car. I drive an EV........so this sort of thing is just not going to happen. Great video.

Beetle . I’ve gotten this thing replaced the whole part . Before my car was smoking from the hood . I leave it in the shop to fix . They fixed it and two weeks later again it’s coming up. Not low coolant . Always something with this beetle.

The problem started with this temperature light on my Mk7 2014 model everytime I checked the coolant it was just a bit low and when I open the can just a small pressure would come out and the coolant will go back to normal. I decided to top up.with water and this stopped but the same night the temperature gauge started to move beyond normal and up to 130 sometimes, sometimes would go up and down while the car is in motion. I took it in and they changed the water pump but the problem persisted, they checked the radiator and also the auxiliary water pump and yet there is no change. They now thinking of changing the whole panel cluster board. Remember I only drove this car two months before this all.

i have my coolant light come on and my rad fans do not turn on, i just replaced the fan module could it be the coolant temp sensor 2010 audi a4 2.0t

My A3 shows a generic coolant light when I start the car cold in the winter. As soon as the oil temperature gets to 100F it goes away. I don’t have any faults or leaks. The shop I was taking my car to said it was normal. This is normal right?

As he was Filling the Coolant to the Max Level! Look at the bottom is a small leak dripping #confused

Has anyone ever come across Insufficient Engine Cooling / Coolant Flow P00B7 on the MK7 R Engine. Mine has had this error come up on warm startup 5 times over the past 5 months. Its always been straight away after a warm start and stopping and starting the car clears the error every time. I have never had it occur on cold start or when driving. When the error is present it puts on the EPC light and restricts engine speed to 4k RPM. The engine does begin to overheat if you do not restart the car. To me it seems like the thermostat is sticking closed but it is very strange how it only occurs every month or so and is fixed 100% of the time by restarting the car. If anyone has any experience with a similar problem let me know. P.S. The car is Revo Stage 2.

Closest thing I found on KZfaq to my 2.5L 09 Jetta overheating. It only happens while the car is idling. Could I get some insight on why this is happening?

Do I have to use the Pink Coolant? I could only find a greenish blue Coolant at my local Walmart. It said for European cars and had an Audi in the list.

So I added green coolant before watching this video. Haven’t started the car yet. How do you suggest removing the coolant from the reservoir?

I cant find any leaks anywhere but my coolant tank was low. Last time i probably had my coolant level topped up was about 2 yeaes ago. So is it normal for the coolant level to drop?

I have a 2011 GTI. Coolant is full. Coolant light is flashing. Could it be from the lid not be securely tighten? I notice when I check the coolant level the lid hasnt clicked when tightening?

Mine came on and it said coolant system Fault turn off engine but the engine is not over heating at all and fans are running good. !??? What can it be ?

Nice video . In my case: no leaks, new expansion coolant bubbler , wiring to until the cluster is ok... red light flashing . I am thinking that the instrument cluster might have gone bad, which is expensive.

What if you use the purple G13?

I purchased Coolant from AutoZone for my B8 S4 last summer. It was what they recommended through the website. What are long term effects, and would it be AutoZone's fault for recommending me to use their product if I end up damaging my engine by overheating issues?

Great video i have a 15 gti, and the check coolant warning came on! But my temps are normal and there is 0 loss of coolant in the resivour tank is it okay to drive still?

Have same issues on my 03 touareg Idk if its because i fill it to max ( cuz this is a reason for lose ) My coolant just dissapears but no leaks I changed my oil cooler stil got the same problem but i noticed it loses coolant mostly when i use A/C but still no leaks what can cause this Sry for bad english hope u understand

Nice jacket!

Update to everyone here. G13 coolant has been replaced by G12 EVO coolant.

I have an issue were the dealership didn’t solve and cannot find any post on the net in regards to the same issue, please reply so i let u know the issue; i have this issue for over a year now!

if anyone has a VW/Audi 2l Turbo diesel, check your coolant flange, they are common to leak since they are plastic

Very useful video. I like VW and last year I bought VW golf 1997 model. In the 90’s I had VW beetle which doesn’t require water or coolant. Very strong car. This month I imported G13 coolant for my golf. I have not yet used it yet. Can any one share me the appropriate ratio of water to the coolant for east Africa countries, particularly for Ethiopia. Thank you for your support.

Please help mi vw polo blow water out through the reservoir i have change the cap and thermostat bt stil no change bt it does not over heat everything seems fine.wat could be the coz Please help

Hi, I have a couple questions, is there a Chat where I can ask you a few questions about my car? Because I believe my car shop is ripping me off for something my car doesn't even have.

I used the green

Gracias amigo me allodo tu video Dios te bendiga

My Jetta 2012 coolant light comes on flashing but coolant level is on point. what then are the symptoms of an engine really overheating while driving? I’m planning to change my reservoir bottle and hope the flashing overheating goes away,

Thank you this was helpful

please do a coolant flush procedure on an MK7 Gti

I have a 2016 Mk7 GTI with 46k on it and I’ve added coolant twice to it. Sometimes in very cold weather after I park in my garage, I can actually smell coolant. I’ve looked everywhere, and I cannot find a leak. I also don’t think that I’m burning it. Does the stuff evaporate?

So let me get this straight: if the coolant level is low, add coolant mixture? Okay, gotcha! 😉 hehe jk thanks for the video as always. Had this same issue and just added distilled water because I live in a hot climate. You didn’t differentiate in the video though, or did I miss that? Tap water isn’t good, right?

Hi I have a Q7 3.6 l 2009 and yesterday hid a noise on the right side when I got home had water falling on top of the right front tire. Need to know how to access the reservoir to see if it cracked or have a broken hose. Thanks Auggie

I just added water, i forgot to close the lid and drove for like 1 hour , the car started overheating I stopped , coolled it off and filled with water because i couldnt find g13 in pink

I usually check my Coolant level when the light comes on, After I check the door to see what brand to buy...

Thank you.... I appreciate it.

Had this issue with my MK7. Water pump was leaking at 34,000 miles. Had it replaced under factory warranty.

This happend to my 2012 VW Beetle Turbo so I left if overnight at work in -20c weather and the engine was cold enough to drive to the dealership.

Can I use g40 pink color coolant

Good tutorial bro

My Audi A3 has lost a lot of coolant due to the hose being loose on my drive to the shop this morning. I have now fixed the hose so should i just top back up the reservoir?

What about coolant getting low when using ac? What about the coolant specs for VAG cars? Many many questions unanswered...

I've got a 2010 jetta 5 1.6 tdi I replaced the water pump but my coolant light still comes on and my heat gauge doesn't rise pass half any idea wat could the problem bru? Would highly appreciate your feed back thanks

I've had thermostat issues with my B8 S5, and have had to drive home or to a dealer. I turn the heater on full blast and my engine temp will stabilize for the drive. Is this dangerous for the engine?

Excellent video

The same thing happened to my GTI last week

Dislikes from people who put green coolant 😂🤣

Coolant leaking from the transmission hose we couldnt figure out how to get the clip in place

I have a VW Golf 1.9 TDi 2003 -Says in manual to use G12 but can I use G13..? Can I mix with tap water or bottled water to dilute? Thank you.

Hi I just wondering how long can the coolant be stored once opened? I have the 2018 cayenne, would you recommend using the Porches OME coolant or other brands work fine too? Thanks.

I have a Seat Leon 1.6TDI estate. The level was low and I topped up with Green/fluorescent coolant... what issues can this cause? I assumed it would be fine.

While we put cooling in do we leave the car on while doing it ?

Great video - thank you!

Quick question my coolant was sitting at below minimum probably like half a centimeter and stupidly went and bought g13 coolant and topped it up probably no more than 200ml and didn't realise I had to dilute it is this a big issue if I add water now its probably gona go to the top of the line or even over should I tip up with water or can I leave it?

At about 5min it sounds like you say Dextron which is a transmission fluid. Did you possibly mean to say Dex-cool?

I have a leak so big that its losing colant when I am filing it,and using it every day like this

Replace the flange.

Good video!

My coolant boils and the radiator fan not switching on, what could be the problem

I have an Atlas and this morning when I went to heat up my car that light came on. The day before the outside temperature was -15 F. I opened the hood to check on the level and it was ok but I noticed the texture and it was like a orange mermalade so I heat up my car for like almost 20 minutes and I went to work now I’m concern if I did wrong by moving my car and maybe I will have a problem with engine in the future.
