Air Intake Temperature Sensor....
Hi Guys, wonder if you can help. About 3 weeks ago I had an issue with my car whereby when you start it the revs would go to about 2k then drop to below 300rpm and fluctuate until a steady idle is achieved. I took the car to a BMW Stealership and they ran a diagnostic check on the car.
It came back saying that the Air intake temperature was faulty. BMW traced the problem from the ECU back the to the sensor and found corrosion, they cleaned the connection up and all was ok… Until now, it’s playing up again. I wanted to check the sensor myself but I have no idea where to look for it, some article around the net have suggested it’s built into the MAF.
The car is a 94 318is with the M42 engine…
Any Help would be very much appreciated.
