Why does My 2000 mod BMW 328i heat up so quickly? on 2000 BMW 328i

After starting the heat gauge climbs fast to max. The red light comes on! I stop Immediately, and then re-start, and the gauge stays at normal but does fluctuate slightly in the upper zone. I do hear steam escaping from within the engine bay. When the ignition is first switched on there is a 'clicking' sound like a short circuit from the radio area of the dashboard.The car has done 280,000 Km, and has never given any problems till now! Please help

It is hard to say without being able to do some basic diagnostic tests. You could have a stuck thermostat that is not allowing engine coolant to circulate to the radiator where it would be cooled down or I have heard (but not aware if your engine would have this problem) that some BMW water pump (some Ford models, V8 Jaguar models and some VW and Audi products) use a plastic water pump impeller that can either slip on its shaft or fail all together causing overheating problems especially noticeable in town driving.
