I have just had the clutch replaced in a 2013 A4 Avant with 178K on clock. Since then low oil pressure warning light has come on the garage replaced the sensor and said oil pressure was great. Since clutch repair coolant has been replaced twice and oil pressure light has come on again. Taken car in to another garage, lost confidence on original garage, who reported a long list of things that need to be replaced including oil pump, water pump, cam belt and a few other things that will cost around £1500 with the warning that the engine may not be any good after repair, i.e. no guarantees. We have a couple of cars and it only does about 4000 miles per year and only has social use, i.e. shopping ..... Prior to the oil light coming on it was driving very well, it is in very good condition for the year. It has literally been driven for 3 to 4 miles with oil pressure light on. Not sure what to do, seems to good to scrap - any advice gratefully received.
