Why is the ABS light comes? My speedometer wuit working after the fan clutch was replaced? The autolock quit locking by itself. The rpm doesn't work. The temp goes to the red? Even the engine temp is not hot

Hello sounds like a possible concern with a speed sensor -- not sure which, but a speed sensor signal concern would influence an ABS light, a speedometer concern and possibly even an auto lock concern. Hands on testing with BMW compatible diagnostic equipment is essential to determining cause of failure and what needs to be done to fix the vehicle. Note that the fan clutch replacement may or may not have any influence in the failure. www.repairpal.com/repair-shops
