Faulty ambient temperature sensor?

ppiotrek · 01-22-2017, 04:02 PM

Hi!

Recently I noticed wrong temperature readings on my E90. Once I start the engine and go for a ride the temperature will quickly go down for even 10 Celcius degrees. Should I replace the sensor or is the issue somewhere else?

Thanks,
Peter

Hey, nobody replied yet and I have also problem with my ambient temperature sensor. It reads 104F when it is 65F outside.

Sensor harness usually gets damaged or sensor needs replacing.
