AC not working

Tellmee · 06-09-2019, 01:15 PM

My AC is not blowing cold air... I have taken it to local mechanic and also the dealership. Apparently, there is basically nothing wrong physically but the computer is not getting correct reading on my pressure sensor even though the sensor is not broken. I have read that some people had same issue and fixed it by flashing or coding so that the module communicates again with the sensor. Has anyone experience this or have any insight on how to fix it or can code/flash it?
Thank you.

Is your A/C system full of freon?

Yes it was filled by local mechanic and then re filled again by BMW dealership. That is not the issue.

Fixed the AC. It was rear stratification sensor code (9C69). The wires by the rear vents were crushed. Fixed them in about 15 mins and AC is Ice cold and I am happy.

Could you please explain more what the issue was, why would electric wires get crushed, it does not make sense.
