Servus zamm, I mainly drive low speed road (1500-2000 ) Since a few days my V70 has been accelerating worse and worse. Today the computer has reported “engine maintenance necessary”. The diesel filter is new. Running power about 380 000 km. The turbocharger whistles slightly but according to Volvomeister not yet alarming. Does anyone have an idea before I drive to Volvo? Can the TL fail? I can’t hear it anymore. Can the particulate filter be tight by driving too low? And could a fast highway tour blow the free? Thanks for every hint. Need to run the car as a fresh family father cheaply again. Greeting Benjamin
