I've noticed the same issue with all TDIs vs. IDIs. My volkswagen diesels (86,91) always had great heaters until the first TDI (99), now they are absymal. Land-Cruiser would cook your out of the cab (3B 4 cyl IDI diesel) and the newer 1HZs have no heat. Cummins 6BT - I can plow snow for an hour and the thermostat does not open. I get away with a truck cab, winter front and a Kodiak in my 109, but I have a webasto that's going in over the winter.
