I am a recent and proud owner of a S6 C6, and therefor also new here, so I do apologize beforehand in case I break any rules or regulations. I took over the beast a few months ago and I’ve recently started to experience a blinking CEL. This being scanned and read as P0302, misfire on cylinder 2. After some testing for the occurance of this, it does not happen during (low rpm+low load), not during (high rpm+low load) nor (low rpm+high load), only during both high rpm and high load. I started with the basics to try to figure out the cause of this inconvinience, and tried both swapping coil and plugs to rule out the easy ones. The intakes was carbon cleaned less than 20kkm ago and replaced injectors 7kk ago. Therefor I have made the assumption it is not caused by;
Leaving me quite baffled and honestly confused, and thats why I am here seeking assistance and hopefully someone who has experience a similar issue. To be clear, this does only happen on a single cylinder, so it does not appear to be caused by fuel delivery, clogged airfilter, clogged cat.
Any help and suggestions would be greatly appretiated!
