I could say that it works too fine, you can't almost hear the diesel sound, it works almost like a petrol engine. The only thing is that you can't feel the power, and it doesn't matter if it is cold or warm. The car smokes only in hard accelarations, the exhaust smells ok. The only thing i don't like is that the automatic gearbox changes to fast in higher gears. I checked the car on a computer and everything is alright (injectors, supercharger), the only thing the computer said is that the car lacks 10% of air, and the guess is that it is the MAF sensor. What is CEL?
