temp gauge

[siilver]

rite i got a problem wit the temp gauge on my 2001 polo

the problem with it is it all down to its lowest point for now reson at random times and then comes back up slowly

but its sits normal at 90, as it always did, but then falls

any help y this could b??

I've got the same problem and could only put it down to the sensor being faulty or sticking, this is a complete pain especially in this weather.

I dont really want to take it to my dealer as I think they'll just replace the thing and cant really justify the cost for fixing something that ok at the moment

Does any have any ideas?

Someone with VAG-COM locally, who could scan your car for issues?

then maybe you could replace the temp sensor yourself? cheaper?

i have no problem workin on the car r gettin a local person 2 wrk on it it

thhe thing is it wrks fine, sits at normal temp

would they pic that sort of thing up on a service
as im gettin serviced next week

as i have never got the car serviced b4 as only got it
and dont no how vw work

If you are getting it serviced next week, then id be tempted to wait - you could mention it to them when you go in to have a check and then if anything needs doing or replacing, you won't have to pay labour costs twice

thats wat i was thinkin
think il just let it go for now
the engine stiil sits at normal temps, so thats cool

think i can live with it for a week

thanks for the help ppl

Let us know how you get on

ah dont worry i will

if your fuel gauge is messing about too then it may be the voltage reugulator
if not the coolant sensors are fairly cheep and easy to do (leave the expansion cap on so the air lock holds back the coolant) try vag parts

when yopuve got the engine cover off look for a place where a few coolany pipes congregate. (usually either on the front or somewhere above the clutch). When you find this look for a pipe with a wire going into it. this is the sensor. Replacement ones are available at www.Vagparts.com.
To replace it slide out the black plastic clip that secures the sensor then pull form the pipe. quickly fit the new on with a new clip and O ring. It helps if you leave the coolant cap on as this seals the coolant system, this means you loose less.
while your in there chenc the engine earths as they dometimes do dodgy things like that.
