I am going to pick up my BMW 2014 335i from the dealer who put a new battery in and they informed me that I had a parasitic draw from my after market accessaries. They unplugged them from the fuse box and the problem was gone. I have a ALP with three heads. bluetooth, hifi and a stir plus as a separate unit with escort live module. The units are about 1.5 years old now. The BMW dealer tech said that they were delaying the car from going to sleep. Normal sleep time is 20 minutes but with these units in it was 45 minutes. They also saw when the car was shutoff a huge spike after 15 secs and then a slow downward draw for 45 minutes. I am going to take it back to the electronics installer but wanted to see if anybody had any suggestions. When I brought the car in all 3rd party units were functional.
Thanks,
Chris
