Parking Brake Fault and Dash Lit up Like Christmas Tree
So, last week my wife calls me in a panic saying that all the warning lights are on in the dash and it's saying take to BMW immediately. Parking brake failure, dynamic drive fault, ABS fault and a bunch more warning messages.
Pulled the codes and they were all pointing to Right Front Wheel Speed Sensor. Replaced the sensor and the faults didn't go away. Having been down this road before I immediately suspected the ABS Pump Control Module under the hood.
Removed the coolant tank to get at the six screws holding the ABS module in and had it out in about 5 minutes. It's a great design as the electrical control box just lifts off the pump block and you don't disturb any of the hydraulic side of the system so no bleeding or reprogramming required.
Sent it off next day air to Module Repair Pro and in less than 3 days (and for less than $100) I had it back and after another 5 minutes to reinstall the control box I started the car up and all the lights are out again. What a great affordable fix to what used to be a quick $1000 hit to the wallet.
