Help and advice needed please - my Megane went into limp mode and the warning light said Fuel injection error in November. I called recovery and a new cam shaft sensor was fitted. This did not fix the problem, the fuel injection was checked and bypassed but this didn't solve the problem either. I rang a Renault garage and had it recovered to them in November. They have put on a new battery, fitted a crank sensor and a new timing belt. Again the problem has not been fixed and the garage has been appalling in dealing with my car and have just left it to one side. I have only just been able to pick up my car (after lengthy discussions relating to paying for work carried out that I hadn't authorised - long story) and the error message has now changed to Engine failure hazard. I have driven the car home and it now drives over 60 mph but seems to lose power before each gear change. The initial problem wouldn't allow the car to go above 43 mph and continually lost power. My issue.... do I try and get my car fixed elsewhere or sell with problems as detailed. The car is a 2010 plate and has 122000 on the clock. Sailed through MOT last May but was involved in an accident 2 weeks after. Car was damaged at the back but the insurance company paid out £1800 to repair. Had the car back 3 months before the fuel injection error. I have owned the car over 3 years since 70,000 miles on the clock and the miles I have added are motorway miles back and forth to work. I like my car but as I don't know anything about cars I am not sure what my next steps should be. Any help appreciated, thanks, Kirsty.
