Hi. Trouble with my Ficht. It runs fine, but after a while around 4000 rpm it goes into limp mode. Alarm goes of and symbol for overheating lights up. Have tried new t-stats, the water pump is new. Tried to measure resistance in temp sensor port side, but don’t know what the readings should be at cold/warm etc. Also the threads broke of when i tried to take it out so this has to be changed anyways, but would like to know if the resistance is ok. Anyone here had the same problem or could help out?
