2017 MK7 Golf R: All owners please read!

There is an issue with the ECM programming on some of the 2017 models. During the catalyst warmup cycle on initial start, misfires are detected causing the MIL/CEL/SES (which ever term u prefer) light to illuminate.

My car started having this issue at 2k miles with misfires on cylinders 2 & 3. They cleared the codes and a TSB on this issue instructed them put a cleaner in the gas tank. Light came back on at 2200 miles and now cylinders 2, 3, and 4 have recorded misfires. An engineer was flown in to run tests a week later. After testing they replaced the front O2 sensor and a radio backup camera module that failed during testing.

After all said and done there is an update that is being developed to fix the issue which there in lies the problem. This is a know issue for only 2017 models and they have no ETA on when the update will be released as it has to first be completed then submitted to the EPA for approval. For a normal car MFG that's not that big of an issue. Since it's VW and they are currently best friends with the EPA, a fix for a low production vehicle is a very low priority. At this point I am stuck with a brand new car that throws a fault light every other tank of gas.

I've had an overboost light but nothing more I'll keep an eye out for this one
misfires happening that often could cause problems in the future I'd love to see how VW handles this one

I have 6000 miles on mine and never seen SES light.........yet

You've done 2,200,000 miles already? Holy hell... (2200k miles)

I have the issue described, except no CEL yet.
Started to idle funny first thing in the morning at 2K miles or so, it was sporadic and at 5K continues to be.

VCDS will show an intermient self clearing cyl 3 misfire error. Car has been scanned 30 times by now, only seen the error twice. (DSG and DAP error more often)
Logging it will show a constant Cyl 3 misfire during warm up. 0, 0, 2-9, 0

I had my complementary tire rotation and inspection done on Friday at 5K.
Car was not scanned due to tune, but I mentioned it to my service rep and he confirmed there is something being worked on.

For all my spell check and grammatical error posters I've attempted update the post to appease your need to provide useless replys.

Thanks for the heads up.

Don't let the assholes get to you.

Thanks for the information.

What exactly is "SES"?

 

[Bobo1]

What exactly is "SES"?

I think he means CEL but could be SES "Service engine soon-ish"

Ah, ok. There are about 1,000 terms for "MIL" - should have guessed, thx!

 

[lcubed]

What's MIL?? Isn't that the dreaded mother in law?

You lost me at "they are currently best friends with the EPA"

I was getting similar CEL lights on my 2016 and the guy swapped the coils between the bad and a good cylinder. The thought was if the problem returned on the same cylinder, then it was a problem central there, otherwise it was a coil issue. I haven't had the light come on since.

So the coils are fine and it was either a coil connection issue that was fixed in the swap or something else entirely. Good diag technique.
