Ambient Temp Sensor Calibration?

[v8z4]

The ambient temp sensor in my 03 Z4 is always about 5 degrees F off. Is there a way to calibrate it or does this indicate a bad sensor?

Hi, I could be wrong here so someone please tell me if i am, but I dont think they can be calibrated. If its reading wrong then its a new sensor. I cant see them being much to replace either

Guess I'll get a new sensor and see if that solves it.

Thanks,
Chris

I don't know about the Zed, but in the case of other models the dealer's diagnostic device has the option of recalibrating the ambient temperature sensor.

You can also reset the sensor by disconnecting the battery. It works, but - if the sensor is faulty - usually until the next visit to the car wash.

There's a BMW service bulletin concerning the sensor - you can look it up here:
