I have a 1997 Renault Grand Espace 2.2TD which has behaved itself fairly well for two years until....one day I accidently left it ticking over for a long time. It overheated, boiling the contents of the cooling system on the floor. I switched the engine off and let it cool down for several hours. After refilling with coolant, I hopefully turned the engine over which it did quite happily with no horrid clanks or squeaks. However, the dash injector fault (squiggly zig zag ) light was on and I don't know how to get it off or reset. Loathe to bin the Espace cos its good elsewhere. Any Espace expert got a solution for me? Thanks
