Spark Plug / Coil Issues 16 RS7

[reddevilb7]

was out doing test pulls on the 104 file and 104 fuel, I am APR stage 1. I have run 104 a few times before. near the end of my pull I lost 2 spark plugs or coils (will find out tonight when I change them) cylinder 1 and cylinder 5 misfire that will not go away now. Has anyone else experienced this issue before ? My car has barely 30,000 km on it and I would consider my driving to be spirited at best I do not drive it like I stole it everywhere. Im thinking it might have been the fuel and the fact that it was only 3c degrees out.

Most reports of misfires have occurred when getting on the throttle hard before the vehicle is properly warmed up. If it was really cold out, did you monitor oil temp before mashing on it? You can switch to lap timer mode and monitor temps closer than just the rpm lights moving. Do you have anything to clear the codes, VCDS, APR dongle, OBDeleven, Carista?

There are rare reports of misfires that are not really resolved and some have removed the tune as a result to eliminate the issue. I have only seen that posted 1-2 though. Mostly warming up to temp.

I've experienced the misfire on cylinder 5 perhaps twice and both times it was the result of "gunning it" while the engine was, apparently, too cold. Once oil temp is above say 180, I've no further problems or repros.

yeah the first time it ad happened to me it was cold out and my oil temps were not very high yet but it went away. the other night my oil temps were up perfectly and I had been driving for about 20-30 mins before getting on it. we pulled everything out last night and 2 spark plugs were toast, I mean nothing on the end, if i can upload a picture I will. We scoped both cylinders and nothing was there so i got extremely lucky
