The ABS light on my '99 Passat went on with a beep and flashing instrument brake light. What's strange was this started happening after my wife heard a loud squealing noise from the rear passenger side wheel (with and without the brake), which went away after she stop and put the car in reverse.
The squeal never came back, but I changed the pads and rotors all around anyway (about time). I also checked the wiring on the ABS speed sensors and cleaned the front sensors.
Using VAG-COM, I couldn't connect to the ABS module (no response) but got this fault from the ECU:
18014 - Rough Road/Engine Torque Signal from ABS: Electrical Malfunction P1606 - 35-00 - -Chances are it's the ABS module. Thoughts?
I'm thinking of sending the module to autoecu or modulemaster to get it rebuilt. Any advise/preferrence on which?
Thanks.
