As others have said, the first step is to repeat the bleed process to eliminate any chance of air pockets.  Monitor the coolant level to make sure it does not go down..

If it wasn't broke why did you try to fix it?

when you filled the cooling system did you:
open the bleed screw?
fill till coolant/water came out of the bleed screw?

when bleeding, did you keep:
keep the expansion tank open?
turn the heater on full blast using the AC button?

Sounds like there is still an air pocket. There are 2 air bleeder screws on that car, one obvious in front, another on the left, drivers side, in the us, or the far side in England, except it's a left hand drive car which would actually make it the near side?! of the block toward the rear. To the googler! for a view of them.
