Hello everyone,

i have an Audi A6 2006 3.0 TDI Quattro Automatic (DPF) and the car is in good condition. I am having an problem with this car, when i turn on the engine and i put the transmission on D to drive, everything works very good and the car is very powerful if i want to accelerate but after 2-3 km the car doesn't accelerate anymore. When i want to accelerate, the rpm goes high to 3.5/4 but the car doesn't react, when i drive without accelerate it the car works very good but can't accekerate again. The car doesn't have turn on any icon like Motor Check or DPF icon in instrument cluster. What do you think? I have checked with multiple computers and software and computers show me not any data error. I have changed Turbo, Flowmeter, Unit Motor Package and again is the same.

Do you have any idea? Sorry for my bad english.

Hope that someone can help me with the answer.

Kind Regards
