Took my skoda superb 2016 to a garage as the engine management light came on and after reading a post on here this possibly being caused by glow plug which was true and was repaired by my local service centre not skoda and the light disappeared, but in return they have left me with 3 faults one is an error:cornering light(AFS), a Front assist unavailable, and they managed to disable completely my cruise control. And they informed me that they are not liable because fault was there before which it wasnt and then they informed me that they do not know what may of caused it but it was there when they took it in the workshop and before they done the diagnostics, plus they would not be able to fix the mentioned faults. I will take it further, imagine the frustration it caused me being told i had the faults on when there was only one which was the engine management ligh.
Could someone tell me how much would this all pleasure cost me there abouts to fix, as well what may of caused this while they done diagnostics and changed the glow plug to build a case, and could the faults relate why the cruise control is not functioning? Any advice would be apriciated.
