Booked a MOT and full service for my car. Took it in but only the MOT guy turned up so had to re-book service for the following week. Within 1 mile of leaving the garage engine light came on and stayed on. Booked it in again for a diagnostic and they said they had fixed it. I also asked for the rear brake pad warning light to be dealt with - it wasn't. Now engine light came on again within 3 miles. Took car to a PROPER garage and they found: Engine light was due to a hose not connected to the air system, brake sensor needed changing, sump plug washer not installed so oil leak and the cover covering the sump plug had gone.
