Take your BMW back to the shop that did the work and have them repair it correctly. They probably ran the car on the lift which will set an ABS Sensor code, so have them properly scan and re-set the ABS module ( from the above question ) or fix it. You may need to find a better shop. it sounds like they don't have the skills to deal with a 740i, which is a complicated machine with many computer systems.
