Does anyone have access to wiring diagrams? I am trying to find one for the Intake Air temperature sensor, which I believe goes to the throttle body and so on!
Reason: I'm still having trouble with cold weather starts and power cuts around 4000rpm (only when weathers cold) when weather is warmer it runs fine! need to get to bottom of this before cold weather disappears, otherwise I'll have no chance in finding the issue!
Some good news - I randomly disconnected the Intake air temp sensor when cold the other day and the car continued to run instead of stalling and drove as it should perfectly throughout the whole rev range! I'm getting 4.9V from the plug for this sensor and an earth.. so replaced the IAT sensor but it didn't cure it. Absolutely stumped.
2006 GTI (BWA engine) if that helps, cheers.
