Hello,

2005 Audi A4 1.8T Quattro, 167,000 KM.

Changed all 4 coils about 1 1/2 months ago.
Spark plug were change at about 120,000 KM

Got a CEL light on and had friend scan with VAG COM with following:

Any ideas what I should check. I read here to clear code, change around coil packs and then rescan. (Will have this done today).

Also read to smoke test to find vacuum leaks. Does anyone know where to smoke test and at what location in engine to start from (At friends place now and he is asking me).

Also, told to disconnect MAF and see if codes go away and only left with MAF code.

Any other suggestions
