I had something similar years ago. I hit a sinkhole on the highway it was really bad and everything seemed like it broke. All lights came on I thought it was done. Pulled over turned off the car and drove home. Two bent wheels but no loss in power or anything. I took it to the dealer under warranty and they said sometimes when u hit something so big the sensor acts up and does all weird things. Never happened again.

This one is a bit thicker than the other positive cable. The other thick positive cable comes on top of the battery and gets connected there to a bolt, which underneath gets directly connected to the battery post by a plate. This one therefor bypasses the BST. Like I said, I don't know what each of these cables power, but even after BST blows up, there is a second thick wire attached to the battery positive terminal. I don't know if this would power the starter or not. But this is what I see when I look at my battery. (I see a third positive cable that comes there, but this is thinner, probably for some accessory)

And also on the negative battery terminal, there is only one black thick wire attached to it, via the IBS, the rectangle metal thingy. If IBS is broken or something like that, there is no other cable to by pass it to provide negative battery connection. Now, it may be not connecting well raising the resistance or having intermittent issues, or the sender wires got broken or detached (the two small wires that come to the IBS) those are different story.

My mechanic changed the BST and it didnt work. Brought her into BMW today so all I can hope for is not too expensive.

Turns out one of the computers busted and they have to spend about 2 hours reprogramming the new one. About $1000 all together just for hitting a pothole.

oh wow... Got warranty?

I see you are in NY. Those NY roads are disgusting. Night and day with MD where I work. Since changing from run flats I have been driving gingerly in NY. Roads are just bad!!

RFT plus XI makes pothole hits explosive.

Ahhhh yes. This is true.

This winter I hit a pothole at night on highway. Not only my headlight housing brackets got broken, but also the aim adjusting mechanism inside the light housing assembly got dislodged. The shock literally hit my teeth against each other, the worst I had experienced. That was my 2nd set of RFTs and pushed me over the fence to ditch them. Now have regular tires with a tire repair kit and pump in the trunk, much smoother. RFTs are really harsh at discontinuities on the road, and XI front shocks bottom out easier making it worse.
The OPs cost is worse then mine, I only had to buy a used headlight assembly and replace it.

please post the parts replaced/repaired or service invoice when complete..sounds odd

[alex492]

I dont have the invoice on me but it was one of the modules, cost about $250 for the part and then another $600 in labor because the computer needed to be reprogrammed.
