I bought a 2009 CPO E90 back in Mid August and everything was great. Around early/mid September I started to get a TPM Sensor Malfunction. My car has been in the shop for about 2 weeks now and it is getting really frustrating.
I didn't buy a CPO car for all this to happen. They can't figure out the issue, they switched out all the sensors already, moved the module receiver, and changed out the wire harnessing and the issue is still there.
If they can't fix the issue, when is it considered that the car is a lemon? Is it possible for me to get a full refund back on the car?
Any info would be great, i love driving this car and would be even happy with a replacement one
