Corsa Engine Management Light – P0171 lean bank 1

 

This customer came in complaining of the engine management light coming on. It had been into other garages for the same fault, but the fix never lasted.

The fault code that was stored was a fuel trim lean fault P0171. We got to the bottom of this issue using our diagnostic equipment and smoke tester.

After replacing the faulty part, checking the vehicles parameters confirmed the repair. A very happy customer then collected their car and have reported no issues since
