e90 323 overheat

Hi All,

I have overheat problem for my 06 e90 323. The issue happen intermittent. When i driving with red overheat light on, i stopped my car immediately and open the engine cover. I found that there is some collant running out from top of the expansion tanks (see attachment).

My garage replaced thermostat for me, and i have purchased a expansion tank cap. Hope it helps.

Just would like to get advise from BMW brothers. If the water pump failed, will the collant leak out from the expansion tank cap ???

Thanks a lot.
