engine is a ALH 1.9tdi 90hp as per vag use.

after a drive to work, 16 miles or so, I have a few things I noted.

1. no overheating signs, temp gauge set on 90 deg c.
2. top rad hose hot, bottom hose cold.
3. looses a bit of water over 2 weeks or so.
4. cabin heater works fine, then you do a overtaking manover, and heater
goes cold, then warms up again.

mpg is very good, avg on a 16 mil trip is about 58mpg.

any comments welcomed

An odd one!

I would guess at an air lock and/or faulty water pump.

Airlock, Sticky thermostat or your waterpump's on its way out. Finding the
leaks probably a good idea as a 1st step.
