Washed the car this evening after LOS, drove a couple of miles and the engine management light came on.
The manual says.
"The check engine tell tale light will illuminate amber if the engine management system detects a fault with the engine system that may result in damage to the engine or environment"
Lovely, but it doesn't tell me what to do next. So can I assume I'm okay to complete the LOS in a counter clockwise direction at the weekend. Or should I call the factory.
