So Im thinking -
MAF
16891 - Idle Control System RPM Higher than Expected.
P0507 - 35-10 - - - Intermittent
16486 - Mass Air Flow Sensor (G70): Signal too Low
P0102 - 35-10 - - - Intermittent
ECU - This is normal?? From other topics on the net, it just means there is fault codes stored on the system?
01314 - Engine Control Module
013 - Check DTC Memory - Intermittent
This could be a bad one. Theres a guide on the net for testing the flap via vagcom. Going to do it soon, but have seen photos of entire dash boards ripped out to replace it? The climacontrol things is working perfectly and blowing strong

01274 - Air Flow Flap Positioning Motor (V71)
37-10 - Faulty - Intermittent
Thanks
