My Z3 `has a short where fuse F7 door lock fuse blows upon first activation. In addition, I see the brake and DSC (dynamic stability Control) yellow warning lights come on intermittently. There is no code showing up on my Peake R5/fcx. This intermittent condition occurs even when the fuse has blown. Is it possible these 2 systems are connected or having wiring in the same proximity to each other? (The brakes and stability seem fine when the intermittent lights come on. The lights could come on or go out while driving around - I can't point to anything that triggers this condition).

Where should I start looking? I did try a 7.5amp in that F7 position, but it too blew. Any help would be appreciated.
