Title: Brake Fluid Reservoir Wiring Repair? Little Help?
Post by: bht2109 on May 13, 2017, 12:02:08 PM
Hey everybody, got a little mystery here for you:

Seems as though a critter got under the hood of my M42 318is and made a snack out of the wiring that comes out of the brake fluid reservoir cap.  Observe:

So I have some questions that I need help with:

1.  Does anyone know if this wiring harness assembly can be purchased as  a single replacement unit?  Scouring RealOEM has not yielded any results (though I may be blind).  Does anyone know of a part# for this harness?

2.  If this can't be replaced wholesale, does anyone know what sort of wire, or what gauge, I should purchase in order to repair it?  I've done a little bit of soldering in the past, and I think I have the skills to get it done, but I thought I'd get the opinions of the experts first before I warm up the soldering iron.

3.  Why am I not getting a warning light on the cluster about this?  What exactly is this wiring connected to?  Isn't this a sensor to measure the amount of brake fluid?  Am I being a complete idiot about this?

Any advice would be most appreciated.

Thanks!
