Help have problem and warning light came one saying low water level. I stoped at garage about 100 yards away then it spat all it's water all over the floor the top rad hose was like a balloon let it cool down. The temp gauge never went above half way so it did not over heat put water in got home and warning came on again. Let it cool down filled it up with water bled the system took it for a run got back and the top rad hose was pumping like a hart about 3pm across I think it could be water pump or thermostat what do you think. It's only done 80000 with full service history can you help please thanks wayne

Forgot to say 2003 x5 4.4

Is the bottom hose a lot cooler? If it is then it could be the thermostat sticking/failing...

I take it that there are no suspicious coloured smoking at the tail-pipe...

No no smoke will take it round the block see if bottom hose is cold let you know in 10 min thanks wayne

hi mate i had this with mine when i first got it only the once think it was an air lock never done it since

Hi top hose very hot and the bottom hose was warm any ideas where the temp sensor is and the thermostat I have bled the system so do not think it is an air lock

But for it to have an air-lock at this stage would me a faulty pipe?

Looked on Internet I could be loads of things f**k going to be expensive I thinks

If it is telling you "Head issues" then lets do other tests first...

Do not thinks it's the heads looks like it could be thermostat water pump or electric valve for the heater and air con all look exsencive giving BMW a call in morning
