Would the battery not have to be disconnected prior to this? It did on the merc I had...

People I have spoken to and the information I have read on forums all say practically the same thing(s) that it could be. An ABS sensor. ABS module. Steering sensor. Steering ANGLE sensor (is this the same thing?).

ABS sensor, officially called pulse generator ABS, is located in the car's wheel carrier, the part number is 34526756379 for front and 34526756380 for rear. ABS module is the control unit, which is the central computer that controls DSC and ABS system of the car, part number is 34516758627, 34526758629 for repair kit. Steering sensor/steering angle sensor is the same thing, it located in the steering wheel column part number is 37146760232. All part numbers are for pre-facelift X5.

Got my x5 back from stealer the same day after turning it in for yellow abs,brake and dsc lights came on.It turn out to be R/R wheel speed sensor parts and labor $217.50 O' and service engine light also so replaced mass air flow meter $402.32 so ran me about $700.00 total,i know ouchhh,WTF...but it runs so smooth now.there was a couple of other things which i didn't agree with and would have cost a total of $4,700..Ya right, i will have my own mechanic look into that

Had same lights,but was due not ABS module,but due to faulty engine wiring. Replaced at 70k miles,no problems after that. Hopefully your problem is a cheap fix,as mine was about 3000$ at BMW dealer,as no one else wanted to deal with it
