2015 Vw Tiguan -Flashing Check Engine Light, P0304 Cyl.4 Misfire 2.0T GDI

The methods used in this video can be applied when diagnosing misfires. Not all engines are the same so the procedures will vary.
In this video we are diagnosing a misfire on a 2015 (not 2013) Volkswagen Tiguan. the check engine light is flashing and the engine has a severe misfire on cylinder 4. A few components have already been replaced, so our direction is based off of that and how this engine sounds when it cranks. I hope you enjoy this video and thanks for watching.

I love the technology! I’m old enough to have done this type diagnosis with a vacuum gauge, compression gauge and leak down tester. Not having to hunt through every cylinder on the engine is a real time saver. Plus, you have the scope traces you can print and show to the customer, coupled with an explanation of what’s going on. It makes us look like we know what we’re doing! 😎

[@Diagnosedan]

That was a great capture! Well done!💪

[@mikem1014]

Dan the man I see you copied my post ... but then i posted after you so i copied your post ... ha ha ... auto techs are talented ... yes we are! HAPPY NEW YEARS !

[@intrapg]

Best diagnosis procedure I ever saw VW repair video.

[@tdracing13]

Great work! I really enjoy watching you go through the diagnostic process.

[@codysautodiagnosticsprogra8706]

Nice capture! Awesome to be able to see the compression out and pulses in the intake.

[@mastertech8306]

That last capture was amazing! I've started to use my Pico more and more these. What a powerful. A tech with the knowledge and skills to use it will be unstoppable. Like you! Great job, man!

[@SuperMarioDiagnostics]

Great to see you back buddy! Well done brother 👍

[@HamiltonLandWorksLLC]

Man that was a perfect capture for a demonstration. Doesn't get any better than that. Great job man!!! Great find.

[@dylankinch2735]

This is one of the coolest captures ive seen in a while man. Thanks for showing us

[@33798]

You're diagnosis are perfect and am loving to watch your videos

[@throttletherapy9998]

I had an 05 dodge caravan that came into the shop with a broken valve spring, another shop told them that they needed an engine and they didn't rin any checks on the engine. The van sat for about six months when they brought it to me. I didn't have a scope at that time but I did run a compression check and leak down that's when I found the problem cylinder. This one had a dead cylinder all the time. I bought my pico about 6 months ago and it has been a time save and eliminates guess work! Thanks for showing the video! I will be getting a pressure transducer very soon!

[@baxrok2.]

Very impressive diagnosis Tom. Wow, right down to the valve. Well done sir!

[@tam1381]

Excellent video,not seen many broken valve springs in my day.

[@calebmohler3082]

This is literally one of the best videos I've ever seen. Good job man

[@francisphillips8192]

Brilliant diagnostic approach

[@lesweiner8444]

excellent. The 1st time I saw that problem was on a 1988 buick regal with a 2.8l. the problem was opposite though. missed until engine ran for a few minutes and then clear up until the next cold start. the coil on the spring would lock back in place after heating up. no relative compression or transducer back then....just a big old analog vacuum gage on a Sun engine analyzer caught that one! great work, its good your passing it on like your Sensei.

[@herminioguzman4887]

Excellent work. Thanks for sharing. I just had a similar problem in a Pontiac, it took me a lot of work to locate the fault and if I had used the oscilloscope and the tests shown in the video I would have found the root cause of the problem quickly and easily. This video is very valuable to me. Thanks again

[@gregjones8501]

Great capture and find bro! I really understood that the entire way through the video and elimination process ‼️

[@8power0]

PLEASE MAN KEEP YOUR GREAT DIAGNOSTIC VIDEOS COMING REALLY APPRECIATED THANKS AGAIN !

[@kevincampbell8298]

That transducer and a scope are a must in my opinion. Yes expensive but much more reliable diagnosis!!! Great call!

[@jamesl197999]

Awesome video. Shows why having a scope and a pressure transducer can save viable time.

[@wysetech2000]

Well done as always, Tom. Funny how it had compression until oil pressure in the lifter was enough to hold the valve open.

[@andrewk778]

Excellent diagnostic video. Thank you for sharing. And welcome back.

[@themechanic6117]

Solid diag and easy to follow! Great work 👍

[@michaelelison1006]

Great investigation and thought process and may well be the very issue I am experiencing right now on the very same model and year.

[@darrenflounders2803]

really good diagnosis, scope saves the day again

[@VoltageDropDiagnostics]

Top notch video, and diag. I'm glad you're back to making videos.

Nice diagnosis Tom & great video! Great to see you back...keep them coming!!

[@JoesAutoElectric]

That was a fantastic video all around! You had a great teacher huh? The entire approach and thought process here is brilliant brother. Love that last capture where you had and then lost it. All found with non-intrusive testing. Can't say how much I love this one man. Great job! Tell me, is this a common failure on these engines? I don't see enough of the Euros to know.

[@PositiveLeadDiagnostics]

I have seen this problem a few times

[@train4905]

[@grumpysgarage4790]

Glad you’re back. Good Diag, nice waveform.

[@pisanski]

Nice video thank you for taking the time to show us that case study. Keep up the good work

[@simonparkinson1053]

Just done one on a 60s Chevy van with a 350 V8. Don't see many of them in the UK. Found that one by the conventional leakdown method though. Telltale cranking sound and cold exhaust header were my clues in this case. #8 intake valve spring was broken into 3 pieces. Same customer has an old Bentley S3 with what sounds like exactly the same issue, but I will be working on that in a few months' time. Nice to see different ways of approaching the diag, and especially the little quirk where you had compression for a few seconds until oil pressure built up fully in the lifter!

[@nateklein7342]

Tom's like a young Paul Danner, he must be so proud.

[@nelsonnarciso1791]

Very well explained video. Good call on spring diagnosis. Awesome.

[@tedjohnson64]

Stellar troubleshooting! Bravo! It’s pretty sad though that VW has these sorts of failures in 100+ year old technology (valve springs). Perhaps I’ve lived a sheltered life, but I’ve never heard of a valve spring breaking on a Toyota motor.

[@billrimmer5596]

That was a GOOD one! U knocked it outta the park. When u first heard the consistent cranking, and then it went away, u were onto the scent. Quick and wise use of the tools! Reminds me of the Diagnose Dan doorhandle. Although in his vid, there was some blood on the knuckles in his vid. Man, we have some great channels on KZbin!

Great video...nicely explained...confirmed with little dismantling...pico 1...spanners 0

[@davidwhipple3832]

This is a great example where a compression gauge could have messed you up. Even a cylinder leak down test May or may not have shown the problem.

[@kellyr9388]

good to see your back..

[@codo7]

The scantool lead the way to looking at four, the ear heard the compression issue while cranking, the pico shew where the problem was and the eye found a broken spring. You studied under Paul Danner, if I remember correctly. Good job, good job. I am sure your boss appreciates you doing what you do for him. That is, I hope he knows what you do with the tools... does he ever buy the crew lunch and eat it with them?
