Got in the car tonight after work and started the journey homeward bound. After about 5 or 10 miles I looked down at the dash and noticed that my Temp Gauge was reading 60, it was fine the last night I looked which could only have been 2 or 3 minutes earlier.

After checking the usual items and found nothing out of the ordinary so I continued my journey home, keeping an eye on the oil gauge just in case. Once home I left the car for about 15 / 20 minutes and went to check it once again, this time the gauge was reading close to 90 and stayed there while I drove the car into the garage.

Any ideas?

Thermostadt?

Thermostat, engine pull? Other stuff to get done while the engine is out?

The thermostat was changed a few months back when the cambelt was done @ MRC. So I'm not expecting that to be an issue. The car run's normally, when I turn the heating up I get hot air. The coolant level is fine also. I'm thinking it's either the sender unit or the dashboard gauge that's got the problem.

Coolant Temp Sensor - common as muck......

Any ideas on where it's located and is it easy enough to replace from the top or is it alot easier from under the car?

Its down the back of the engine, you can change from the top, if you order one from Audi order the plastic C clip also, as mine broke and I think it was about 20p.

Part Number anyone?

Thanks

If its the same one that causes the fans to continually run if it fails, try this ebay number. 180549837530.

I had to change mine recently, its not too hard to do and is located at the N/S rear of the engine bay.

Take the air box off to get in there.

It may be worth checking all the thin Vaccum hoses under the airbox too as a lot of mine was badly perished.

Plenty of other threads regarding the replacement procedure on here, use the search facility.

Spot on, Thanks. I've ordered one of those. Already ordered vaccum hoses as I've been told that they don't last very long and can cause problems. I've checked out the Spark plug sticky so have an idea on what's needed.

Cheers
