Hi, my V70 D5 from 2003 with 310,000km is only 200 km/h for a few weeks, according to Tacho. Before it accelerated quite quickly with three-quarters of gas to where it then controlled. Now it does not accelerate so quickly and creates with ach and krach downhill at full gas I can remember the following relevant events: Do you have an idea what slows the moose so? I have read here already something of the marten-knappered hoses on the intercooler. How can I check whether the L adepressum is sufficiently high? Probably you will hear nothing, because the engine is simply too loud at 3,000 rpm. Would be grateful for a push in the right direction. Greeting, wrecked
