I need help...electrical issue
2002 325i with 93k miles on it.
Bluetooth DIY done about a year ago.
My dash lights went out recently, I took it to VOB BMW in Rockville (a mistake), they told me that the bluetooth phone system caused the cars electrical problems. I took the car home, removed the system, and believe it or not the car started working again. Trouble is, the tailights were out on it because they reprogrammed the DRLs and I guess forgot to reactivate the tailights. So I took the car back the next day, but when I got in the dash lights, AC, and stereo were all not working properly. They called me today to tell me they have no clue and that they want a $390 diagnostic fee.
I'm currently looking at getting a new car, and I took it in originally to get it ready to sell.
What should I do?
