Im an idiot.
Had a hired car to go to manchester for a conference/meeting thing in Manchester, a focus sport tdci, very nice. Getting back, it ran out just as I was getting home, so put £10 worth in to get me to work the next day. This morning, wouldnt start properly but managed to get it going, drove bout 1/2 a mile with it sounding bad so pulled over, rang my mate in work, who asked me the obvious. Doh! Im waiting for burnt trees, recovery people now.
Anyone else done this?
