Hi Guys,I'm currently driving an E90 318i (2006) model. Just came back from Auto Bavaria. Sent my car in to check on white smoke expelled from car exhaust. Prior to that, there's a minor leak at from the gasket. According to the technician, they need to do a top overhaul to fix my car and they quoted me RM15k to fix it. How much does it cost to do a top overhaul from a regular workshop? Can anyone recommend me a workshop located in KL/Selangor?
