p130a00 + p030600 cel flashing and EPC light on

[ichi d]

So this morning I started my car and the engine light was flashing and it went off and the EPC light stayed on. Car had a very rough idle and felt like it was going to stall. Once the engine warmed up I turned off the car and turned it back on and the EPC light went away and it drove fine. Drove it to my shop and they pulled this with their snapon reader. P130a00 and p030600. Anyone else have this issue or know where I should start? Tia.

Hi
On what cylinder? Sparks or coils problem i think

Rs6 Performance, Catless Downpipes, Straight Exhaust, Loba High Fuel Pumps, Forge Intercooler, Arma Intake ....

Cylinder 6. But I had some misfires in other cylinders can't remember which ones but I cleared it and it all went away. Mind u it's like - 30 here and it happensd on a cold start. Would it be safe to drive Still?

I would check the sparks because mil on does it mean over 60 misfires/1000Umin and thats not really good....

replace the spark plugs and make sure they're gapped correctly per recommendation.
OEM is a little wider than the recommended gap for a tuned car but a lot of the time you won't have any issues either way until it gets super cold.

Car is driving fine now but I will replace the plugs. Don't think they have ever been replaced. 13 with 53km. I'm stock now but will retune after the winter so what gap should I run it at?

Hello, it’s becoming a common problem. Slot of 4.0TT guys st heaving misfires. Mostly on one specific cylinder. I have a 2015 RS7 that had a cyl#3 misfire. I have tried everything as far as plugs, injector cleaning, carbon cleaning, coil pack, still no fix. So I purchased a brand new ECM from the dealer ship ($1400) and installed it and programmed it my self. It’s been 1 day and so far no more misfire. I hope that was the issue. I spoke with the APR guys st SEMA this yes ein Vegas and he told me he ran into the same issue and it ended up being the ECM.

I purchased a $1400 ecu and I still have a misfire, new coil, spark plugs, tons of injector cleaner, and I have a specific cyl #3 do not waste money on the Ecu it’s either an Injector (highly doubt cuz someone in here changed it and still had a misfire) or a mechanical engine problem such as a piston ring sticking or a valve spring wearing out
