Mein Auto: lots of cars
Arrow Tell me about the ABS Module

My 1999 528it has a rebuilt module in it already and seems to be dysfunctional, It was in there when I bought it.
I see new ones for sale in the $400 range and to have mine rebuilt in the $150 or less range,
Sometimes I read that I will need to bring the car to the shop to program the new one and other times I read that its plug and play,
Mine shows the code for front left sensor faulty, Mostly at start up,
Sometimes the ABS/ASC light comes on after a few feet or a few minutes of driving, When light is NOT on all works as it should in my slippery driveway,
I replaced the front left sensor with OEM part and no change,
INDY shop says just because it shows front left wheel does NOT mean that the ABS Module is NOT at fault,
SO I am trying to save a bit as I just has to put a clutch in the car,, The O2 sensor just went bad and I would like the ABS/ASC system to function properly,
IF I send mine in, Can I drive the car with no Module in the car?
WIll it need to go to shop to get programmed?
Have I other options like a reasonably priced NEW unit?
OR anyone here have a good used one for me?
Thank you
Peter B

Sometime it's not the sensor but the rings (teeth like) from the wheel bearing. Try to clean the ring and see what happen.

Yes for manual gear box but I would not drive it if I have an auto, the shift will feel funky.

A rebuilt of your abs module does not require. Coding

However it is likely the module cannot be rebuilt again. A new module will require recoding

From more reading I am finding that no-one wants to rebuild a rebuilt module and the $400+ price is really too much for me right now,
Is there another way?
The ABS/ASC is important to work for me as I am using this wagon for my 300+ mile drive once a week, and its an advantage in my mind.
Looks like Ill have to sell my god or something,
Is there a place where they are LESS THAN $400 smackers?
