Temp prob
« on: 27 January 2008, 16:32 »
The temp needle has been dropping from the 90 last few weeks so i did a DTC scan and it came back with:

16500 Engine coolant Temperature Circuit-Range/Performance Problem

So I thought it would be the temp sender and brought a new one. However after fitting it it is still droping and the same code comes up :angry:

Anyone got any thoughts? Maybe the sensor in the tank or thermostat   :undecided:

1.8T BTW  :smiley:

about £30 or so i think mate  :undecided: not sure if the sensor is in the cap or the tank itself.  Mate of mine had a problem on a 150 TDI Bora and VW replaced the whole tank.  fairly certain the sensor for the 1.8T is in the cap though  :huh:

Magic thanks for that rhys. I think i will replace the thermostat first, As you say then do the tank next because if i do both i will never know which one it was  :grin:

This is my first engine problem since i got her 55000 miles ago so ive been quite lucky :evil:
