Increased battery discharge - EDC module

BIMMERPOST
     Featured on BIMMERPOST.com
Just dealt with a few weeks of an increased battery discharge warning. The dealer had some trouble with this warranty repair in making the proper diagnosis. Went through a new battery, junction box and some charging switch replacement before a faulty EDC module was found to be the parasitic drain. Tricky one. Read another post where this was a cause. Wonder how common this has been.

There are a number of inputs on this both on M3post and M3cutters so you're not the first. Curious, didn't the fault generate a code the dealer could pick up on?

Yes. Just saw that a search under EDC module yields lots of info. But it did present with the increase battery discharge warning and various other warnings associated with the loss of charge - fuel pump malfunction, loss of traction control, loss of auto start stop, EDC failure, etc. The dealer did not pin point faulty EDC immediately despite reading all the codes.

Ah, got it. Not easy to track with a pile of different codes. Glad it worked out.
