Ok so can anyone please tell does the ambient temp sensor located on the wing mirror have any effect on the running of the car?
E.g for the ecu to read with regards to fuelling?
Mines well off the right temp! I'm not bothered about it but could it affect the car

The hotter the air, the less dense it becomes. Therefore if you've got less air then you'll need less fuel to burn with it. If theer were a link then your car would be running lean, not rich.

So don't worry about the ambient temp reading :thumb:

I do recall having it come up on PP2000 when I was working a on 207cc the mirrors were off the car, but the car at the time had issues running, we had to replace the AATS back to clear the BSI codes. Cant say for sure if it effected the running as we did a few replacements together, but the De- poll warning was fixed up after!
