I am a Volvo newcomer and have been driving a second-hand V70 engine with 140 hp Bj.02/2002 with luxury and combination package for 3 months. Especially during the hot summer I noticed repeatedly that an activated automatic climate control system, very often (sometimes up to 3 times per minute) resulted in power cuts in the form of jerks or restless driving; … and that especially when the vehicle was cold! I was driving a passat with automatic climate control, where this effect could only be felt when the vehicle was very fast. My Volvo dealer said that the behaviour of the vehicle was completely normal. Is this really standard, in a vehicle that is in competition with the A6 and the E-Class? In addition, I wonder if it is normal that when the doors are closed centrally, it is not checked whether windows are still open. I know it from other vehicles where the windows may be raised.
