I'm getting CEL lately, on every hard acceleration, got codes:

4 Faults Found:19497 - Powertrain Databus: Implausible Engine Temp. Message from Inst. Panel P3041 - 35-10 - - - Intermittent16502 - Engine Coolant Temp. Sensor (G62): Signal too High P0118 - 35-10 - - - Intermittent16684 - Random/Multiple Cylinder Misfire Detected P0300 - 35-10 - - - Intermittent16685 - Cylinder 1: Misfire Detected P0301 - 35-10 - - - IntermittentReadiness: 0000 0000 No noticeable drivability issues. I guess my major problem is the cylinder 1 ignition coil? Will swap coils to confirm. In case of faulty ignition coil should I replace all the coils or only the faulty coil? Are there coil options (models) I should look after? (Some parts sources offer multiple brands/models). The P0118 (CTS) is something I could live with.. P3041 – what’s that? Thx,

replace all...that's exactly what I did on my 2003 2.7T MT A6. There MAY be a recall on OEM coils, the dealer said.

Checked with dealers:
Audi has never had a recall on ignition coils...

Replace them all. Audi has had issues with coil packs for years. Technically they are not the subject of a recall. However, they are the subject of many Technical Service Bulletins. Audi replaced all 8 of my coil packs for free under one of the many TSBs.
