I have a 97 a4 1.8tQ with abs and brake light on. Car was scanned and was told that it was because of left rear abs sensor open circuit. Just to be sure that means my sensor is bad not the module? before i buy a new sensor tomorrow. Thanks

 

yes, the wheel speed sensor, a lot cheaper than the ABS module.

 

Thanks for the quick response wolfs. Just wanted to make sure thats what i needed to replace.
