Thanks Plasticmac, wee update, just to be safe, I have changed the thermostat and I still have no heat inside the car even after doing a 30 mile round trip to my local MOT centre as well .If the thermostat was not opening at all, you'd have no heat. You should get a VCDS scan ASAP, as the FSI has an electronically controlled thermostat, and a scan will show what's going on. If the stat is not opening at all, the engine will overheat, and suffer serious damage. Better safe than sorry.
Anyone know where I can get a copy/purchase VCDS for myself, I already have Delphi and an older Snap-On diagnostic tools but VCDS would be better.
On another note, I also need a recirculation flap motor or at the very least the small white lever that connects the motor to the flap as i snapped mine. Thanks very much for any help guys, it will be greatly appreciated.
