First of all, I’m looking forward to: I’m from Dortmund and I’m a proud owner of a Volvo S80 2.4 petrol engine with 170hp and approx.160tkm from 1999. (All maintenance intervals were maintained and the car is a checkbook maintained) I’ve already read some threads that I’ve sometimes found very helpful here. Especially this one: http://www.motor-talk.de/…/…overtake-repair-t2835658.html and this one:http://www.motor-talk.de/…/…s-steuergeraet-repariert-t192 3830.html What moves me to open my own thread, which can be read in many of these threads of different symptoms, such as speed drop or expose the cruise control etc.. However, these symptoms do not show my moose. The moose drives quietly, has no start problems, does not go out and also the speed in idle is constant at about 900. Nevertheless, the error messages worry me of course. In the appendix I have the list of the evaluation of the error codes. My experiences In the area of “screwing” are rather small to classify. Alternator off and install, as well as changing bulbs etc. I got gloriously. (Not on this car) Based on the error list, what can you tell me? Should I remove and send in both the ABS control unit and the throttle flap? Please help my sick moose (and me) 😉 Addition: By the way, the whole thing started with the following error: Photo in the appendix
