Hi and welcome to just answer.
As the performance has not been affected then I would carry on using the vehicle and get a diagnostics done at you convenience.
You will probably find it is something menial has triggered this light and just needs the fault code read and then deleted to eliminate the warning light.
hi but what does "eng ctrl faulty " mean
engine control can be triggered by any sensor on the engine that is reading either exhaust gases or function that is outside its parameters .
I find that 9 out of 10 times I reset the fault with a scanner for it not to come back again.
thank you for your quick and reasuring reply and i will take your advice
your very welcome.
