Its either a fault with your gauges sender unit or a problem with your thermostat. Is your heater still hot when the gauge drops?

It will be a gauge issue then, either a dodgy electrical connection or more likely a faulty sender unit.

Post in the mk4 section. I'd replace your temp sender and thermostat with genuine VW items.
