Hoping for a little guidance if possible. A chap asked me to scan his car to double check a garages suggestion before paying for more parts.
Short story if I understood it correctly:
- car working perfectly fine
- took it to a garage to replace rear springs (one had snapped) and front drop links (worn)
- on collection, the ABS/ESC lights were lit on the dashboard
- garage blamed the front left speed sensor and ordered a replacement
- took it back to the garage for a new front left speed sensor
- on collection, it had both the previous ABS/ESC lights and now also the steering light
- told to take it for a drive to see if the faults would clear
- faults remain so they now suggest a new ABS module

We did a short test drive and front left showed 0 km/h where as the other three sensors looked plausible. To me, that suggests a wiring issue between the ABS module and front left speed sensor. Possibly caused by the garage disturbing the wiring during the drop link replacement.
I've suggested he have the garage load test the wiring, check the reluctor ring is clean and check the clearance before considering a replacement ABS module.
As for the steering light, I checked the adv measuring blocks in 44 Steering assist while moving the wheel:
- Steering Torque (G269) was changing
- Steering Angle Speed was changing
- Steering Angle Sensor (G85) was static at 0°
- Calibration Status (G85) was 'OK'
Not 100% what the cause is but I fear that could be be a disturbed connector? It only appeared after the garage removed the battery box and disconnected various wires when trying to figure out the ABS/ESC light issue. I've suggested that the disturbed connectors are all double checked but I'm not totally convinced.
Anything obvious that I've missed or other advice/suggestions I should be giving the owner before going back to the garage?
