Morning All,

Looking for some pointers as i have tried everything i can think of.

I have a 2010 Q5 2.0T that runs rough on idle i have replaced various parts and now i have hit a brick wall and not sure what to try next.

Parts replaced: PCV Valve, N80 Valve, Coil Packs, Spark Plugs.

Current engine code is P2188

Any ideas from you guys and girls would be appreciated.
