“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.

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.

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..

Dude I am having the same issues AGAIN on my tsi. Absolutely fun to drive but would not recommend buying this car unless you are rich. And if your filthy rich buy something better

[@kpuco011]

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.

[@uzzuzz9320]

2009 Tiguan cylinder 1 3 4 still having intermittent misfire after changing all plugs and coils. It happens sometimes when accelerating it kicks back.

[@CoolAirVw]

check fuel trim and trouble codes.

[@kimtutorials3116]

Could be fuel injectors?

[@CoolAirVw]

@@kimtutorials3116 yes, but you could list off a dozen things that it "could be".

Going off the broken lock tabs you talked about in this video. Have you ever considered doing a video showing a wide variety of electrical/ vacuum/ sensor plugs commonly used on VW/ Audi and how to get them apart without breaking anything?

[@CoolAirVw]

Excellent idea

[@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.

[@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

[@ninvin21]

Could be as simple as excess oil contacting the spark plugs and causing a misfire. Check oil levels,

[@CoolAirVw]

Nope.

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

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

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

[@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 well, it was not caused by carbon buildup:/ he did a compression test and the engine cylinders are fine, did a vacum test and there’s no leak. We’re going to verify the injectors now. Any advice?

[@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.

At that point once I accelerate or slow down the error appears on screen “Check Engine Service Now”.
