The guy who replaced my coolant sensor yesterday persuaded to go for re-map. He took the car in at lunch time and said it would be ready in a couple of hours. At 16:15 I rang him to find out the progress. Here is the bombshell. He said that half way through loading software and ECU stopped talking to his laptop. He said it would take him a lot longer to sort thing out now. Did anyone experience similar problem and how was it resolved? Any advice?
