If I am going to replace it I want to go with a TCU + BT with assist over the old ULF. Should I jus order one before I pay BMW 132.00 dollars to tell me it is broken because I am pretty sure it is.. unless its the idrive..
I had a corvette...
Well as its impossible to tell without hooking up an isid or scanner. I can't help but bt not working is a pretty good indicator. If the most bus is down all your entertainment would be acting funny, and you would prob be getting the heartbeat sound from the speakers as it trys to communicate on it. I have seen plenty of tcu/ulf/sdars modules die in my time. It's not unheard of.
