Vehicle Returned With Engine Warning Light

I am extremely disappointed with the service I have received regarding my vehicle repairs.

My vehicle was handed over without any engine warning light or related issues. After the repairs were completed, the vehicle was returned to me with an engine warning light that was not present before.

The repairer acknowledged that the vehicle did not previously have this fault and advised that the issue would be fixed. Despite this, the vehicle was returned with the engine warning light still present.
