I came back to my 2002 C8 yesterday it wouldn't start. Engine turns but won't start Central locking does not work. Dash displays don't work. No hazard lights. Radio does work (although that's not original) We had it converted to LPG (6 years ago) as you turn key the LPG fuel level indicator goes on but then off. ADAC (the german version of the AA) found a fuse that was dead. Replaced it. Now side lights work permanently when key turned (don't know what or how long that fuse was dead). Other than that he couldn't understand it. My usual garage ... trustworthy .. worked on it yesterday. They are somewhat at a loss. All I can think is when I got in to start it my mind was all over the place (thinking about other problems) and I may have done everything all at once. (turn key, close doors, lights, clutch, gears) I did think I'd caused an immobiliser fault ... went through a reset routine that didn't work, but as AA pointed out the hazard lights would still work Any ideas would be appreciated (other than it knows the last credit payment goes out next month so has died!)
