ok guys so i charged up my x5 last sunday and then itook out fuse 74 i started it on tuesday was good then yesterday it was dead again .. so does that mean it is not the bluetooth module (TCU)?

If fuse 74 completely kills it yes. I didn't do that as I unplugged the tcu itself so Im not willing to say for sure on it.

Ok did you put the fuse back in or is it still removed?

If putting the fuse back in made it drain the battery back down it may be the tcu. I would still try with the tcu unplugged and the fuse in. If the tcu is bad you need to leave it unplugged till you replace it anyways.

With it draining at random I would find out if the tcu is there and unplug it then see what happens. Its hard to find drains so being methodical is the only real method to find it.
