I've a 110 TDI - P Reg which I use daily for work. Parked it up on Friday no problem gone to use it today and no power. Have checked battery and starter motor etc all ok. Have located to blown red fuse 10 amp. Changed fuse but blew again straight away twice. Any body have any ideas as to what could be causing this. Is bottom right hand corner fuse. Help as need vehicle for work

Says on rear of fuse cover what its for,there is a short on that line.

Is this in the under seat fuse box?
