ah shucks. Move to KC and come to work here. I'll teach ya a thing or two.

“I don’t trust the dealership.” This is exactly why I try and take my car to a guy like you. My car is in the shop for this right now; misfires both on 2 and 4, and it chokes so bad at idle, like it’s suffocating. Replaced spark plugs, wires (because as you said, someone worked on it and didn’t know what they were doing and broke the tabs) and ignition cores. I have close to the same mileage as this car, so I wonder if this just part of the wonderful repairs that comes with age. Thanks for the video.

Hello. I liked the video and the easy explanation you have made on the issue. I will allow myself to ask a question - I have an a4 b8 with the cdnc 2.0tfsi 2009 engine. I have a similar problem with P030200 P030000. The problem occurs only when the car is idle (under 1000RPM), once the RPMS exceed 1000-1200 the problem stops and the car runs without issues. So, when the car is idle the whole vehicle shakes and you can even hear the misfires from the exhaust behind the car. The only errors registered were the 2 mentioned above and nothing else. As far as I know the chain is ok, the injectors are new, the plugs were changed, the cylinders and the valves are fine (or so I am told), there was a repair done for the issue with the oil consumption on these engines (the head was opened again after that to check if everything is ok, they told me everything is fine), there is no carbon build up on intake valves. I have tried the official dealership and other high end car services, they all can not locate where the issue is, so here I am. Do you have an idea on what can be the cause or how should I proceed?

[@CoolAirVw]

its not easy to diagnose bad guides that have failed in the way that this engine has. It would require in cylinder pressure sensor with an oscilloscope, and even then you would have to have advances skills to know what your looking at. I certainly dont claim that. The ones like this I diagnosed through process of elimination.

[@josesaldana8058]

Did you replace the rear main seal yet?

[@CoolAirVw]

On this one? no. Lots of others. Diagnosis of rear main seal is usually pretty cut and dried.

[@saraachtmann7711]

Our 2016 Tiguan in the shop.. they said the only way to find the issue is to open the motor.. if it’s something wear and tear is not covered under extended warranty .. 😭😱.. cylinder 2 has 0 psi .. the carmax preferred mechanic said it’s like rolling dice.. also said it’s a common vw issue.. the most expensive Gas has always been used n all the services up to date.. it’s nerve wrecking… the sad part we still owe 10G on it.. hoping for it being under warranty so we can fix and trade it in.. this car should be banned from the states if it’s a money pit..

[@SergioHernandez-bl3yl]

Good explanation! I have a 2011 VW CC with the code p0300 I’ve already changed camshaft and crankshaft sensor as well as mass air flow sensor and coils are good I don’t know.

[@CoolAirVw]

crankcase vent, rear main seal, injectors, carbon build up on intake valves.

[@SergioHernandez-bl3yl]

Can’t get no one in my area to do relearn procedure for crank and camshaft sensor and when I tell some mechanics they’re like I’ve never heard of that so I guess ima just trash it!

[@CoolAirVw]

@@SergioHernandez-bl3yl this Vw Tiguan doesn't have a "relearn" procedure, so your "some mechanics" are right. The test done in this video is for testing and diagnostic purposes.

[@kennethking2301]

In some models of VWs, a bad injector wiring harness will cause a P0300 usually accompanied by P030X (X = cylinder # that is misfiring). I am not certain about your CC. Unfortunately, on the EA888 engine, the injectors live underneath the intake and you may have to remove the intake to test the wiring harness.

[@alfredschmidt3659]

NGK's are by far the BEST plugs on the market. If you've ever had trouble with plugs fouling due to worn engine; NGK's will last 10× longer at least.

[@CoolAirVw]

[@bobbygeorge2261]

Awesome video very in-depth 👍👍 So I bought a NO CRANK NO START 2011 Tiguan that’s throwing a bunch of codes P0299-P304 and P12A2 P0507 & P2187 and pending codes are Pretty much all same plus P0016. I tried manually cranking the motor a couple small turns but W/O a lift it’s tough to get in there. Do you have any good advice for me I’m trying to figure it out myself.

[@CoolAirVw]

If the p0016 reoccurs I would worry its out of time, meaning major engine damage. If it jumps time and the pistons smack the valves it has no compression. That engine usually damages all the exhaust valves. You can hear a lack of compression because the engine cranks over super easy. You can identify this with compression guage or with boroscope through the spark plug holes. Watch the following video. kzbin.info/www/bejne/nHzRZoGng7dqipo

[@elias1995ish]

Can carbon build up cause misfire on cylinders and rough driving at low rpm? Also epc and check engine light? It all started with cold start misfires but car drove well. Recently it started rough idling and misfiring a lot while driving and it was very noticable, engine shaking as well. I replaced spark plugs and coil packs, still the same. Misifiring always from cylinder 2 and 4. My mechanic said it’s carbon build up and we need to clean them, this is a 2013 tiguan 2.0L turbo. Makes sense?

[@CoolAirVw]

carbon builds on on intake valves frequently and causes misfires. Other things can cause it as well.

[@elias1995ish]

@@CoolAirVw what a hassle those engines, he quoted me 400$ for the cleanup, when it’s done I am going to sell it

hello my friend i have the same problem, but already change the head gasket already. What do you think is the problem?

[@CoolAirVw]

if you have misfire then you'll need more diagnosis than "what do you think is the problem".

[@arturomurillo5703]

probably the problem is that infectors you think this is the problem

Please Help with P0341 My 2010 Tiguan has no issues when starts in the morning with cutout driving. The moment I take highway and exist minutes later, the car hiccups epic flashes one with check engine flashes once, and then move. At that point once I accelerate or slow down the error appears on screen “Check Engine Service Now”. I”lol attach my OBD and dealer reports We have done the following but the problem not going away. - Changed camshaft sensor (5 times) new - Changed spark plugs - Changed coils - Engine was removed from car, opened and changed complete came shaft - Solenoid replaced - Changed camshaft wiring - Timing chain is correct - Replaced Tensioner - Oil change (of course) Problem remains the same and more frustrating with the amount of money payed and time spent

[@boazvarcoe1932]

Hi there! Really appreciate your video! My partner took her car to get the coolant changed. When she picked it up, the check engine light was flashing accompanied by another - EPC. We took it straight back and the mechanic accepted no responsibility whatsoever despite me explaining that the car had 0 issues before. Now it’s in limp mode and sitting in our drive way. Is it possible that what you said around 10:52 about air leaking into the coolant could be the cause? If so, where do I check? I should also mention that the mechanic scanned the car when we brought it back and he said it was the ignition coil in cylinder two. After I change that we noticed little to no change at all 🙃 Thank you kindly for your help!

[@CoolAirVw]

listened at 10:52 and I was discussing the cylinder leakdown test where the air from my test tool was going. I dont know how that applies since you dont have that tool installed on your car. These cars develop misfires all the time so it is absolutely plausible that it is unrelated to the work your mechanic did, although it is also plausible it is related to something he did. I have lots of videos on misfire diagnosis, you should employ the diagnosis techniques in those videos or get it to a mechanic you trust.
