started ignition drove of turned on fan to get air into cabin and no air being blown out of any of the vents.

plugged VCDS in when I got home and No Fault found on the Module (I have 2 zone air conditioning , no LED display , just the dials)

Ran all the tests on the module which VCDS allows you to do and everything is fine , including the test which blows air out of the vents so I know the fan motor is working , tested opening and closing of all vents - fully working Etc.

Rebooted MMI , turned of ignition left it 30 minutes and .......turned on ignition and still nothing , no air what so ever coming out of the vents despite turning the fan dial up to max (the LEDS light up as you turn the dial)

PLEASE HELP, WRong time of year to have the blowers not working

Probably the resistor. Changed one the other day. This resistor is fitted to many vag models and is notoriously bad. To be honest the blower motors aren't the best either. Take the glovebox out and you will see it. If you end up fitting genuine parts and have to change the blower and the resistor your looking at about £350 iirc. The resistor is about £80 from the dealer's and there are loads on ebay from £30 there's also a company on ebay who will repair your old resistor. ..which is a good indication of how common failure of the resistor is. Good luck with it.

Looks like this and you only need basic tool's to do it. Philips screwdriver and torx screwdrivers. Only other thing is that when you remove the glovebox you have to diconnect the airbag isolator switch so you might have to clear fault code's in 15 airbag afterwards to get rid of airbag light that might have appeared on the dash.

The fella who's I fixed the other week said that Audi had quoted him £1100 Inc vat. (He brought his own parts and I only charged him £50 for checks and fitting.

No worries. Think it will play up again but you know what to do when it does.
