Intermittent ACC, Start/Stop, Front accident warning failure

[Chrisp]

Hi,
(possibly co-incidence, since some rear body work two weeks ago) I'm getting intermittent error warnings on the dash (and failure of the systems): ACC, Start/Stop, Front accident warning. First time it failed for the duration of two short journeys, then worked for the third. Next day fail then not within the same journey. Also hearing a faint high pitch whistle sometimes I've not heard before.

Any ideas appreciated

Chris

Possible ABS sensor, commonly rear wheel but not always.
You need a Carista OBD reader to identify which sensor.

ABS sensor connections also a possibility especially if the bodyworks were in the rear corner areas. Access to connection is behind the light clusters i believe.
