Halli-Hello, my 280 TE 1983, 3rd series with M110 starts hot/hot after a “cooling phase” of 5-60 minutes only after the fourth start attempt again. First it starts on a cylinder, for 3-5 seconds, then suddenly on all cylinders as if nothing had been done. No ignition oscillators while driving, runs as it should. Another hint; -if I warm up the car and start immediately again, it starts immediately again. So between one to four minutes of service life the engine immediately starts again. Only then from a service life of about 5 minutes until (…) it no longer wants, or – as described above – it starts very reluctantly. And if it is quite cold, (in the early morning e.g.) it starts immediately!? Greetings Tombi
