Hi All i have an fabia vrs... which is trying to kill me!! i was driving it a few weeks ago when the brake light ,abs light and ASM light came on this bllep about 3 rimes then went off ... so i ignored it!!! a week later it did it again so i booked it in @ skoda while waiting for the car to go in the same prob happened but this time the sterring light came on and i lost steering!!! this since has happened twice more!! the last time it happened in knocked the radio off and the engine ticked over really rough and the headlights were dim!! and the whole dashboard flashed!!

i booked it in at kings heath all electric garage who have had it all week... they have now give me the car back saying they car find a fault... or its not recording the fault! any ideas help would be great its an 06 plate fabia!!!
