Well after a lot of f***ing around getting my Vagcom to work on my edition of windows 7 I scanned my S3. My shopping list has now changed slightly.
I got the following errors:
16486-MAF (G70) signal too low,
18057-Powertrain Data Bus missing message from ABS controller
17645,17646,17648-Cyl1,2,4 Fuel Injector (N30) Open circuit
17521-Oxygen(LAMBDA) Sensor B1 S1 Internal resistance too high
So the MAF and fuel injector problems prob explain the loss in power. Bin quoted £60 for a MAF this sound about right? on ebay I saw one for £192??? Vagcom suggests for the injector either, fuse?, wiring harness?, failed injector?, or failed ECM? Now I'm trying to order a service guide from Audi as I dont even no where to start checking these things? Could it be worth a try with some injector cleaner first?
Then any tips on the ABS controller problem would be appriciated my VCom said chech brake elec + communication with brake elec??
