Operating temp 1.9 TDI

[KINGPRAWN]

just got my scan gauge working thank to SYNCROANDY's ECU .... Now I have so much info to worry me !!!
What should the running temp be ... Needle gauge sits bang on the LED ... Scan gauge says 92/94 degC .. Is that a bit hot ???

just about perfect
mines at 89c, others report 90 odd. Hotter the better for fuel economy

WAHOO.... Another tick is all this information good

The operating temp is determined by the thermostat, the standard ones are 89 degrees iirc ? As to the temp seen by the ECU, there's a bit of variance between different temperature senders, even nominally identical ones, and I think VW would have allowed for this in the ECU software, so I think a few degrees either way isn't anything to be concerned about. If it really concerns you try buying a fresh new one from VW and see if it makes a difference to the reading.

Thanks Andy .... in that case I guess I'm within margins !!
