A lot of guys install a coolant heater. Apparently there aren't freeze plugs so
thats not an option. I suppose the advantage of the coolant heater is quick
heat in the morning.
Its interesting to see guys on TDI club saying "now that its cold out", then
you check and they're in Virginia or Georgia. You ask and they say "Well its in
the 40s." In the 40s I don't even wear a coat...

One of my neighbors accross the lane drives a Golf TDI. His solution was
to have seat heaters installed. He is a retired physics prof and he says
that it is understandable that the TDI does not heat well. He says we
are essentially converting one form of energy to another and that is why
the big old V8's created good heat - they were burning lots of fuel and
converting a lot of that energy to heat. The TDI is using very little
fuel and the result is poor heating capabilities.
