Hi,

I have just bought a VCDS to look at a problem have with my Passat FSi.

Although I am not new to diagnostics, I am new to this car and Can bus dignostics.

My engine is failing to hold steady revs at idle and the VCDS reports 9 faults - Pasted below. I am guessing that it is possible for one problem to cause several fault codes to be recorded, so given the information and the faults codes what would you guys think would be the best place to start?

Thanks in advance for any help.

Nigel
