This is a great sight for info. I am new to post a question. My wife brought her 2015 335i into our dealership for an a/c flush after dealing with vinegar smell every time she turned on a/c. She was told she might have to bring it back in for a second flush, which we did end up doing. Second time, I took it in. Used the navigation system to find the correct entrance into the dealership because I am not the one who typically takes the car in for service or routine maintenance. After the flush, I got into the car to leave dealer. Message on idrive screen read "searching". Didn't think anything about it, just figured I would investigate when I got home. Got home. Got distracted. Didn't investigate. My wife drove the car the following day and her phone would not connect to bluetooth. So phone and navigation are not working. We rebooted bluetooth connection. It does not work. The radio works. My wife called the service department and they want the car back (a 2-day hold) to take a look. Everything was in working order before the a/c flush, and stopped working immediately after the flush. Would like to return to the dealer with some knowledge as to what might have happened. The timing is suspiciously coincidental. Anyone have a clue?
