moin moin, my parents have a volvo 850 with the 5 cylinder. He still runs like one. But he has always had a macke. Sometimes he doesn’t start. he tries it, but then he only goes out and behaves as if he doesn’t want to ignite (or just wants to ignite wrongly). Then you turn the key back and then he usually jumps cleanly at the second attempt (just in the third or fourth try) as if nothing was going on. It is possible to mention that he sometimes has a fluctuating, falling speed at the ample. However, he still doesn’t have that long and not all the time. If he is really cold, sometimes a hydrostuttle falls out. However, I don’t know if he is from the inlet or out.
