ABS Pump and Module Failures
Symptoms
ABS light on, no ABS function. You might hear grinding or buzzing from the ABS unit under the bonnet.
Cause
The ABS pump motor fails or the module itself dies. This is common on high-mileage 850s.
Fix
Replace or rebuild the ABS unit.
Rebuilds are available from specialists ($300-500).
A used unit is $150-300.
The car is still safe to drive without ABS, but you won't have it in an emergency.
