I reversed my car on a hard lock two days ago and suddenly multiple warning lights came on - low tyre pressure, Electronic Stability, ABS, Park Pilot not working.

This persisted for 10 miles or so on and off until home.

Went to a garage in the afternoon and paid for a diagnostic check, and the result was a repair:

NSF and NSR ABS Sensor

NSR WBearing

£440 inc Vat.

Yesterday no warnings, drove car as normal. Twice reversed on a hard lock and no warning lights came on.

I don't know/think that the garage physically examined the WBearing - how can they be certain it needs replacing?

Could it be a glitch in the system , should I wait and see if the same error reappears?

Thanks for any insight
