A4 B7 Avant air con inc evaporator

[pharmer]

Hi
My new (to me) A4 B7 Avant was diagnosed by Audi (after £60 diagnosis and regas) as needing a new compressor - clutch was working, gas was good, econ button was off, pressure sensor was good, but compressor was u/s. Managed to get local Halfords to replace at half Audi price. Compressor now good (including regas), pipe in engine bay to bulkhead is cold and icy. However no cold air inside cabin. All servo motors seem to be moving. OBD11 check shows no error codes but probably needs VAG diagnostic? Is the evaporator a possible failure - something seems to be stopping air flowing over a cold evaporator, unless the evaporator is blocked - anyone come across this - replacement not realistic! Comments anyone?

ive fixed the flap by getting new/used sensor from ebay...i went to tyre spot they gassed it and the the air con still never worked they didnt charge me...and it fixed 00819 fault...they think it might be the pump...i get no errors to solve my problem so im not sure what exactly the problem is and how to identify it
ive checked the fuses and connection and get a reading from the plug so it is live....
