Not a major fault??...Could be in over time...The way the injectors work with the double squirt to quieten the diesel engine knock of old if the engine is misfiring on some cylinders could cause problems with the DPF or place excessive strain on pistons, con rods etc..I'm not a diesel mechanic but modern high torque diesel engines are pushing the max so you don't need much to go wrong to cause expensive damage..Well that's the way I think...Regardless, in the 21st centuary hi-tech new vehicles shouldn't have this sort of problem and you shouldn't have to put up with it and Fiat Chrysle has to come up with a fix....Got me wondering whether the problem isn't the double injection..eg one or the other but not both missing in the cycle

Had the new fuel pump fitted yesterday made no difference to the problem, the dealer booked the car in for three days next month to go over it, will give me a loaner.
Also the button that operates the tailgate window failed, needs to be ordered from the US 4-6 weeks wait.
I'm glad it's a company lease car, I hate to think what this would cost if it was out of warranty.
