Mine also went to -40 recently but it is definitely plugged in. Do they also read -40 when they go bad or is it possible I have a bad connection elsewhere?

mine is very strange the -40 has now disappered from the display does it disappear if the sensor is unplugged?

Mine has dissappeared too, was there until I noticed the wire to the sensor was broken(it didnt work properly, obviously, but I had some reading) and soldered it up, I guess its just a faulty sensor :?

Mine seems to have like the wrong level of resistance or some thing, even tho it's new cos the temperature's way out. Does anyone know if there was any difference in the sensor from model to model? I've got a 1990 1.8 16v and vag just gave me this one and said it was the right one.

there's 2 or 3 different ones... get the wrong one and you'll get some weird and wacky readings on it...

 

If the sensor is missing, the MFA will normally skip the setting. If it's faulty then you'll either get no reading (it'll skip it) or a mad one like -40

 

As bix says, the wiring's somewhat prone to getting damaged down there too, so check that out before spending your hard earned... 8)

-40 means it's disconnected. Had the same problem with mine.

 

Jack up, head under bumper parallel to indicator, top of break duct there should be a cable to plug in :)

Of all the faults I can imagine spending money on, this would have to be the least likely :)

Has anyone noticed their reading wandering? I rapidly gave up trusting the reading after about 5 minutes of driving, as there is clearly some soakback from the engine. I was a bit surprised about this, because previous VWs, SEATs have always had a pretty reliable reading here. Any ideas? :scratch:
