Also forgot to say that over the last week the car had developed a very very annoying rattle/squeak from the passenger footwell area. This evening I whipped out the passenger seat and both glove boxes to try and work out what it was and there were a load of wires for the radio dangling down behind the glove box along with a load of other (redundant!) cabling?!
I didn't get any pics
So I tied all the cables up and secured them as well, hopefully that will have solved the problem
