Heater not working, please help!

[Wu11ie]

My car is an 02 1.8t, I've just got the car back from the garage after having the wheel bearings fixed and I've discovered the heater doesn't work!!

The temp gauge goes up to and sits at 90 no bother, but there's no heat inside. The pipes in the bay are warm as is the expansion tank so the water is circulating but I'm just getting no heat.

Has anybody experienced this before?, is there a way I can check to see what the problem is?

Thanks in advance

Probably a stuck heater flap. Common problem.

As above. VCDS can sometimes recalibrate them.

Silly question but what's VCDS?
