Hi all, just had my 330 recovered to a local garage. Was on the motorway only 5 or 6 miles after leaving home, having just stopped a couple of miles back for fuel.

Idrive flashes up amber temperature warning, which turned to red in about 30 secs. As luck would have it just passing services so pull in.

So all the coolant has emptied out of the tank, AA chap tells me bottom hose from rad is cold, while top is hot. Thinking water pump but doesn't seem to be similar symptoms to other failures. Anyone got any other theories?

No, but AA chap filled it up and it all flowed straight back out the tank again.

We'll it was the water pump, sports fans. What's the consensus on replacing thermostat at the same time?

Think both are electrically operated on the E90.

I was advised to change my thermostat when the water pump died on my N52, so I had it done!

OEM parts + labour at an independent the whole disaster only cost a little over £800! banghead

So I sold the car (or is that money pit)! rolleyes

It didn't last too long though, I (stupidly?) bought another and love it (well until it rapes my wallet)! laugh
That's the ball park I've been advised for this - the pump itself from BM is over £400 plus vat! Hopefully once this is done I've only got to worry about coil packs and idrive units laugh
