Hello, need a confirmation for my fault diagnosis or a hint where it might still be (but don’t laugh if I’m too close to it). Problem 1: If it’s a bit colder, it starts normally in the morning or just after a longer service life, but after a few meters have been driven and the clutch is kicked, the speed drops and it goes out (can be handled by “playing” with the accelerator pedal). After a restart, the problem is gone until the next day. the idle control causes the problem? Problem 2: It never gets really warm in the interior. First it takes an eternity until some warm air comes. And if a highway ride last year I noticed that after about 200 km distance, an average speed of approx. 160-180 km/h and about 5 degrees outside temperature the blower has switched off again and again at regular intervals and for a short time only cold air came. Would tap on the thermostat. Right? Problem 3: Exhaust gas values do not fit either. The mixture should be too “greasy”. Co is too high in idle and increased idle. Besides, the Nox value does not fit – I think too high – exactly. Does the thermostat actually have an influence on the air/sprite mixture? Would go to a workshop, but after my last visit there I became more than 1000 Euro poorer and would like to limit the error before I have to pay for the search there or would like to fix the error(s) as much as possible. I am happy to answer, even if you can “only” help me with a problem. Mfg
