Hello, I have lighted up the message ‘Motor system maintenance required’ in my XC70 D5 Geartronic 185 HP MJ2007 198,000km for a week in the on-board computer. The message did not come every time after the engine start but certainly 90%. Until yesterday I was able to drive normally. I thought after the first show I was driving a few days further what happened and look at a specialist workshop only then. Yesterday I got the Tem on the highway of about 135km/h. and then the message immediately appeared and I couldn’t accelerate any more than the ~95km/h said. Today I was able to drive a higher speed again but to safety only moderated and no more motorway speed. Tomorrow I drive into a Volvo workshop and see if they have time for a reading. My first suspicion since the first message appearance was the flap, but after checking the lever arm I have seen that it is the turn and the small actuator is still working. I had the vertebral valve completely changed at ~100,000km at that time. I searched Motortalk for all possible threads but could nowhere find further problems to the warning message. Since I would like to prepare for tomorrow already, I would be very happy about your feedback. My driving profile consists of ~80% highway and only very little city traffic, so I close once Problems with the DPF regeneration. I have already thought about the AGR valve, but what do you think? Thanks in advance and nice greetings.
