Servus… My heart bleeds when I have to address it, but my darling is sick… and that’s been going on for quite a while… Maybe one of you has an idea what it might be about…?!?! My problem: If it’s absolutely cold, everything is still fine, but as soon as it gets to the 50°C it starts. He doesn’t really take the gas… sometimes even so bad that he pulls less and less, the more gas I give… The whole thing is over then (happily doesn’t last too long) If he has left the 50°C far behind… if he is really warm then 80-90°C he runs again like ́ne one… I can’t really explain it… Thermostat and temperature sensors have already changed… So I am grateful for every advice… many thanks LG Deniz
