Oks i ve fitted the New o-ring, by the looks of it it had had the wrong o-ring in it. Also the connection doesn't seam right you can pull the pipes apart i ve got to replace the clip still but i don't think it well make much of a difference any ideas?

Also went to my mates garage and stuck the car on the mobile fault scanner, came up with some faults which was:-
Airbag Faulted - intermittent power faulty or something like that
Radio Faulted - Ariel somthing
Engine electronics Faulted - Thermostat i belive
Clocks Faulted - Something to do with the Thermostat
was something about door module and something else related with the Thermostat i think
Thanks
