I’m at a loose end, please help! S3 8V intermittent rough idle.

@Leedavies_S3 was this sorted in the end? The intake n205 correct the problem?

I have all the same, done everything of the above namely, Plugs, Coils, PCV, Catch tank - going to send the top set injectors in for cleaning within the next day or so (was done about 12 months ago)

I am curious as although im getting multiple misfires on Cyl 4 which is leading me to the injectors i had and still have this issue with the Over performance Camshaft fault (I think its P0011) which might be attributed to these listed above.

wouldnt it be better to switch 3 and 4 injectors around to see if that shifts the problem to cylinder 3 first?

It does make sense but have the opportunity to get them checked and cleaned for free so just delving straight in
I was just curious so that if it doesn't solve the probe 100% I know where to look next

Fair enough. I'd still switch them round though in case its failing rather than just blocked / dirty

It turned out to be my n205 bud, sent it into Audi and they replaced it under warranty.
