was parked up in a carpark with engine running ive now ive come home my mate rung and say ive left a puddle which to him looks like coolant mixed with oil any ideas 

Well, if you are running g12 coolant and it has dripped onto the floor it looks slightly like oil is mixed. How big was the puddle and do you have your splash guard under the engine still?

Was the aircon running?  Could it have been the run-off from that?

 

I would start by checking your coolant level and see if it appears to have dropped (it will be pressurised, so when you undo the cap expect the level to rise a bit)

update noticed a split in brake hose gonna get it sorted monday
