Hello municipality, since the bad 318i BJ 87 of my wife no longer comes through the TÜV, I have with a customer a Volvo 850 BJ 96 170PS and full equipment are offered to the customer. The car is from 1. Hd. and the marriage couple unfortunately did not survive the car. Both dead. So now to my question, but I do not need any purchase advice, so hey mut you buy and blow with 300 over highway. OK. The car is from first hand. Can it be that it gave the Volvo with heater (BENZINER!!!) he has TRACS, this I also had with my first 850er, but I was the opinion Tracs out=light out, but with this copy light the lamp TRACS OFF, at least for the duration of the test ride which took only 5 minutes. I know what has to look at least most of the time. But I need help. 2. Problem sliding roof elektr. does not close a left, but can still be taken to the right, but it’s not as if my 850.
