couple of week, when i took the car for a test drive (this slipped my mind recently) i noticed the engine warning light was on, and on my previous car it was also. i asked why it was on and he told me the mass air flow had been replaced and when the sensors are taken off the car doesn't know its back to normal which is true and said he'd sort it (he did...).
however the state that i found the bulb in had obviously been tampered with, the only other place the car went to was the mot garage and i doubt they are that corrupt

so it has to be that garage. going to ring tomorrow and enquire as to why the bulb has been damaged.
and i suspect he will be in a lot of trouble (legally) so i won't be too threatening, however i will want the problem correcting. and some mats.
