We sometimes have to perform a vehicle diagnostic check to read fault codes that have been stored inside of the vehicles E.C.U ( electronic control unit).

When a fault has occurred it normally indicates a yellow engine light which is displayed on the dashboard. Once this has happened Grays Service Station will enter into your vehicles E.C.U to extract the information that has been stored.


We will then evaluate the results and provide a report of the best way to resolve the issue.

Initial checks take around half an hour to carry out and can be arranged on a while you wait basis.
