water temp sensors

[gavin.starr]

Can anyone supply me witht the part numbers for the black and blu water temp sensors, it think mine are a bit buggered, as the temp doesnt seem to read what it used to, I have changed the thermostat also to no avail.

Its hovering just above 70 but before it was allways around the 90 mark.

Any help would be great.

pretty sure these black sensors are fairly inaccurate, if you want the part number try vag cat or your local dealer ?

Im getting a really rough start up at idle, i remember reading a post on here some where that it was to do with the water temp sensors, and when they were changed it sorted out the issue.

Is the black sensor just for the read out on the dash and the blue on for the ecu.

Would it be more beneficial to get an external water temp sensor with a new thermostat installed into the pipework some where to give me a more accurate readout.

Yeah black is for gauge and blue for ecu. Dont forget its bloody cold at the moment. Mine was chugging a bit on start up until I gave it a few revs yesterday morning. Was fine after that.

I know what you mean it is worse when its cold. But it started it before we were down to minus figures, there only a few quid each so i aint got much to loose if that does'nt sort it out.
