OK, thanks for the advice.

Hillington MOT in Hillington, Glasgow, Scotland. The car was stuttering and went into limp mode. They diagnosed it & said I needed a new injector, new air flow meter & had to reseal another injector. The car is worse than it was when I gave them it. Paid £690 & now they say it's something else and want another £300 to repair the ECU.

If you pay a garage to fix your car & it's still broken, can you get a refund?
