Quick update on this, I picked car up from dealers today its had a recon head put on with new valve guides and seals new head gasket comes with 6 months warranty parts and labour. New aircon pipe and seal plus regas seems to be working at the moment. Drove it 90 miles from Bradford and all seems good no losing water no pressure in the header tank and temp stays at 90 all the way i get hot air from the vents now also. So i hope this is it and all will be ok. Thanks all for your advice. 1 thing however i plugged the laptop into the car using VCDS lite and code comes up as fuel temp sensor open, i cleared the codes and took it on a drive and checked when i got back and no codes found. Has anyone had any problems with this fuel temp sensor? And is it a big problem if it comes back? Thanks again
