you either have to continue trying to bleed the colling system mate ( not aware of being able to bleed carbs) or look at other areas such as whether the viscous fan is working properly.

With your car up to temperature and running stick a rolled up newspaper into the fan blades, if it shreds the paper all is well, if it stops the fan from turning then your viscous is buggered and needs replacing, not too expensive, but the left hand thread 32mm nut can be a kanoot some times

m10's blead relatively easily.

With the rad cap off, run the engine till warm, watching for bubbles in the expansion/radiator tank and adding coolant when it goes down.

M10's often seam to get pressurised by the exhaust, which leads to overheating. You can cure this by jamming the thermostat so its always open. Try this as its help many m10's in the past...

I personally had a problem with the brand new thermo baught from BMW for 42 Euros!!! It never opened up, so I just went and bought one from the breakers.
