This sounds like a coil fault. You need to have ECU read. Doesn't have to be at renault dealer. Lots of garages do diagnostic testing now. There will be fault codes stored even though the MIL is not on perminantly. This will give the cause of problem. And you can rectify. Or you could just replace all 4 coils on top of each spark plug. And hope my diagnosis without the fault code is correct?
