High I've got a coolant leak form around the middle of the engine (underneath) dripping down by the exhaust manifold it's quite a big any ideas where this could be coming from

 

Could check around the turbo area as that has a coolant pipe fitted to it.
are the heatshields removed?

 

From memory, turbo has a rubber hose attached to it with some metal tubing around it as heatshields and also a metal pipe that has a copper washer and banjo bolt.
mine leaked at the copper washer when I changed the turbo.
was quite bad and steam came from the area when I drove it.

 

Could be anywhere , could be the Alloy crossover pipe O Rings , could be as said turbo pipes , could be water pipes coming from header tank , they all go underneath lol

 

Thanks for the advice guys it's dripping from the nsf corner of the engine I'll try and get it up on a ramp all heatshields are still fitted

 

Check the turbo water line (under the turbo). Mine bursted wide open a couple of days ago...

 

problem solved it was leaking out the waterpump then running round thabks for the help guys
