My car has been off road for past 3 weeks after cutting out intermittently and towed it into garage on Sat morning. When i towed it in it would not start at all - turnover but not fire and no go from injectors They have called me just now and told me i need a new ECU as the trim wasn't put back on properley and water has got into it and damaged the board. How could this have happened ? Would anyone have need to access the ECU when i had my car remapped ? I had my car remapped maybe 2 years ago They have told me it will cost around 450quid.....but now I will lose the remap i had done on it. I feel ****. Any Advice ?
