Hello everybody, I was just in my Bosch workshop of trust for the checkbook appointment. After I moved the car about 500m much had told me that the ventilation did not work and gave the car off again. Result: inexplicable, then gave a mass signal on the fan then it ran again. But according to the workshop they were not there yet near the component and only changed the interior filter. The next day I picked it up, saw on the display: Oil level just before Max (1 bar was empty) and drove about, 1 km there came the info in the display: oil level too low 0.5 L refill. So again to the workshop. Result: inexplicable, have 0.5 L refilled. I drove away again and after a few meters came the message again: oil level too low 0.5 L refill. So again to the workshop. I looked at the car from below, no leak everything dry. The next day picked up, the workshop drained the oil and measured everything. in order is, the display shows times 0.5 l refill or 1 bar oil level ok. Result: none, a call to VOLVO but there was no information, Master doesn’t know any more. Here are the errors that have occurred or occurred since the date: -Interior ventilation no function -watch in the display stood up –:– although it was set correctly, Master says he didn’t touch the battery (would there be no reason to) – Oil level display shows incorrect values -Display : no belt in the font though I am strapped – Plug connection for trailers must have a problem, after a few meters the trailer gets no more signals and there are error messages in the display. After I have removed the connections and plugged in again, however, it does not last long. Can someone help me here?
