4x4, ABS, Brake, Self Level fixed...

[Brandon002]

So last weekend I loaded up our bicycles to head to the track. With the bicycles, tool boxes and gear all in the hatch we got on the highway.

I got the 4x4, Brake, ABS errors and then the Self Level Susp Inactive message.

Got home, unloaded the car and started looking in to the issue. I read that it could be a ton of different issues. Well 15 minutes later I started the car and all was fine for a week now.

Today I am headed to my Dad's to fix his car. Load up the X5 with my tool box, jack, jack stands and other gear. Get halfway there and all the lights and warnings come on again.

So I think to myself, is it just a coincidence that these lights come on when the car is loaded up with heavy stuff?

Get home and pull the hatch area apart. I find a black wire labeled "Battery Squib" near the back of the rear passenger seat and see that this wire is basically being crushed by the spare tire, I guess the weight of additional cargo put it over the edge.

So I cut the wire, soldered and crimped it back and made sure it was zip tied tight against the wall so that when the tire was in and weight was on it there was no issue.

Well I button it all up, start the car and all is great. So when you get the plethora of warning lights, check the wiring in the spare tire/battery well in your hatch to make sure none of it is obstructed. Before you go diving at ABS modules, speed sensors, transfer case actuators etc...

Well, off to Dad's I go.
