If you log into 08 Auto HVAC then selct the measuring blocks, scroll through the channel numbers using the up and down arrows until you find the flap angles.

Depending upon what version you are running vagcom will either state what the measuring block is or not !

What you are looking for are the measuring blocks that have a range between 0 and 255. To find the block that relates to the temp flap it will be a process of elimination.

cheers for that... im going to head out in a min to do this....

However i noticed after a further look the collent seems to have dropped....

Does the coolent run through the matrix on these??

The car has been stood for a week in snow etc... however i topped the coolent up and heat seems to be coming back through........

Im going to out and have a proper look now in the light!

Cheers.. any other thoughts keep them coming!!

If it's like the VW Climatronic if you press fan 'down', heat down (blue) and econ together you'll get a display of the settings. Scroll using hot/cold buttons.
Mine has just had a fan motor control ECU failure which has cost a fortune to put right. Symptoms just like yours, feeble heat on Hi, no heat anywhere else.
First indicater (1) showed cabin temp at 97degreesC.
