E85 LONG RUNNING BATTERY DRAIN - NEED HELP IN FINDING A COMPANY WHO CAN IDENTIFY PROBLEM

[SonnyA85]

I just remembered sometimes you can have an intermittent fault with an alternator as in it works sometimes and other times it doesn't might be worth looking into or finding out a way to test it regularly.

I had a Parasitic Drain on my old E85 that BMW traced to a faulty Gaptech Module. Don't know how they found it as it was located under the gearstick console.

The drain on my M was the roof motor, still worked but I've taken it out, disconnected it, and that was the culprit.

My recent battery drain was the sat nav DVD that was randomly turning itself on when the car was locked.

Interesting I have a cd changer but got rid of the OEM head unit years ago. I may need to disconnect the thing and eBay it

Hi everyone, Iv'e been away since the early hours of Thursday morning and only just seen your comments. Many thanks for these. I 'll take a look at these areas and also chat with the auto electrician to try and track down the culprit.
