Hi,
I swapped m42b18 from e36 into my e30. Temperature gauge on instrument cluster doesnt move at all, I replaced several working clusters and result is same, so I am sure that temperature gauge working.
I tried also with 1-pol sensor from e30, and temperature gauge start to work, but it is bouncing and it is in 5 minutes in red line, when I turned engine off, and give contact, then is sensor right in the midle, but when I start engine, temperature gauge is again in 2 minutes in red line and bouncing.
I have original coolant temperature sensor of e36 replaced in my engine with new one, I was sure, that sensor is broken. But also new one it doesn't work on my e30 cluster. Why? This is a 2-pol sensor from VDO (12621747281). Original my e36 engine wiring harness has 2-pole sensor, but it is not moving at all, 1 pole sensor does not show correct temperature.
I have no ideas what to do and check...Please help, any suggestion or Idea will be helpfull...
Thx and regards,
Dejan
