Citroen Saxo Desire, 1.1L. Engine began to run rough. Engine management light came on. Went for easiest option and checked spark plugs. One had failed (oiled up). Stuck a replacement plug in - problem solved, running well again.
Warning light remains on though. I know it has to be re-set using a diagnostic unit, but I keep reading that disconnecting the battery for an hour or so and then re-connecting it will re-set the light.
Anybody tried this - did it work?
