There are no frost plugs in the TDI engine block. That means no block heater.
The TDI heater is a great way to heat up the coolant on those cold nights. I chose the cheaper route and bought a ZeroStart heater from Canadian Tire and installed it myself with nothing but $6 worth of coolant hose.

Everytime you post a picture with PhotoBucket, a TDI gets below 30MPG.
