Clive, don't you trust in the forum ?
Sure, there is a solution, but only for the VAG garages themselves.
The program is called ELSA Win, but it's forbidden to show to costumers and also to use it as a private worker.
But anyway 50% of interested Audidrivers have it
Here are some pics.
It's located right there under the cover (couldn't find a matching pic, so I had to take an internet pic)
If you remove the air intake tube you can see the sensor.
You will have to remove a plastic clip which is shoved in. (not on the pic)
This is the part seperated.
The sensor is only plugged in, so you can pull it apart.
You will find there a small amount of cooling water, which needs to be cold, so you can work properly. So let your engine cool down some hours.
Greetz and good luck,
Chris.
