Took the car in this morning. Explained the situation and showed him the hole behind the number plate (he said this this did not neccessarily suggest a previous boot problem as this is where they would sometimes run the lighting cables when attaching a tow bar). Anyway cut both vacuum hoses (although i could only see the one he told me there had to be two, one to lock and one to unlock, which there were) and not knowing which was which pumped air into line 1 and no luck.
Pumped air into line 2 and...
and...
STUPID S.O.B STILL DOESNT OPEN
Left car with him.
Am over it...
