The transmission fluid leak could cause a foul smell, IF , somehow, the leak was causing fluid to be burned in the engine compartment somewhere and the smell of burning tranny fluid is getting sucked into your heater vents, behind the firewall. I would use this as a last resort for diagnosis, I dont feel like thats the case here. VW's commonly have problems with the A/C - Heater unit, Vents, Condenser, the whole system. Does it smell anything like engine coolant? If you faintly smell a coolant type smell, or like a burning engine fluid type smell, then you have another heater core problem. Do your windows fog up really easily with the heater on? That is a definate sign of faulty heater core. Remember, VW's Coolant system are under vacuum pressure, so if your technician replaced any coolant, added, or flushed your coolant system after repairing the heater core, and he did not repressurize the cooling system properly, a number of things could malfunction.. including your brand new heater core. You might also want to make sure that if he did replace / flush coolant after the job, that he used VW's specific coolant. Its not the same coolant that standard vehicles use. Hope this helps!
