Its the glow plug relay temp sensor circuit playing up. A fairly common fault. Not sure if they are adjustable It is probably a case of override or replace. It could be a rogue temp sender I suppose. Not sure of the resistance of good one :? A lot cheaper to change than a relay though
Does anyone happen to know if the black temp guage sender and the black glow plug sender are the same? Looks like it from these details off ETKA:
8 049 919 501 temperature sender for coolant, oil temperature indicator and glow plug relay
0-125C M10X1 1 pin black X diesel
However it says single pin. Mines got two prongs sticking out of it so i assume thats 2 pin. Is that right? If so does anyone know the part number for it.
thanks
Sorry about the mis-info, I guess my car was just messed up
no worries, any tips are useful tips. PLus the start bolts are loosened up a bit now. Should save some siezing up in future.
