I took in my Girlfriends car to Drive In shipley which had an engine warning light that came on, although it ran and sounded fine. after a few hours of leaving it with them they said they couldn't find anything wrong with it so they cleared down the error code to remove the light and sent us on our way (£40 down!) it came back on a few days later so we look it back, they said the same thing again, cleared the code but this time didn't charge us (rightfully so). It came on again a few days later so we took it back a third time; they told us this time that the head gasket had blown and that it needed replacing which was in excess of £1000. I asked them specifically if they had pressure tested it and it was definitely the head gasket and they said it 100% was. The car didn't show signs of typical Head gasket failure so I got in touch with a friend of a friend who was a mechanic (who I now use all the time) and he looked over the car for me. He said the head gasket was fine and it was one of the engine sensors that had been faulty! He ordered the replacement part for me which was about £17 and we replaced it together. He showed me how to do it and I fit it myself under his supervision. After we finished he cleared the code on his laptop and boom, i've never seen the engine light since. He didn't ask for any additional money but i handed him another £50 for saving me over £1000 from these cowboys! Be warned of this place, if they suspect they can make money out of you, they probably will!
