Plus, and to reinforce what Tim has just said, I 'lost' the indicators on my 08 +4, all fuses under the dash were fine but I found that one of the fuses in the small plastic holder on the bulkhead under the bonnet had blown, it appeared to supply 'some' of the buzz bar in the main fuse board. I know yours is a later car and I am guessing it has the electrical box under the bonnet above the knees but it might also have a line fuse or fuses elsewhere?
