I have a 2000 528i at first the speedo quit. At the same time the abs light and the traction control light came on. I then had 2 of the speed sensor changed.This made the speedo start working again, as well both lights went out. But now when I go to stop at low speeds the pedal thumps and vibrates
Please posters post any helpful info
Clean your plug for the abs/traction control system. You'll find it on the passenger's side of the engine bay. It's a plug about three inches by one inch, rectangular about half way back in the engine bay, behind the windshield washer fluid reservoir...you'll have to pull out the short side of the plug next to the engine which is a latch securing the plug in place. I found rubbing alcohol to be a pretty good way to clean it. If it gets grimy, connections can foul up and cause bad behaviour. This fixed some ABS problems on my cousin's 2000 528i.
Make sure the plug is back in place before you start the car again. If it isn't, you'll get an amazing number of computer errors--as we found out when we accidentally started my 1999 540i with it unplugged once.
2000 5 series the module itself is a very common failure. Most likely you will need to replace the module. Its not a cheap part, I belive retail is about $800 and it must be encoded by a dealership after installing so total cost is usually just over $1k.
As far as other options, getting a used module is not a good idea because it was such a common failure. Also I dont believe any aftermarket parts are available at this time.
