If its the symbol of the engine....then it is the emissions light.....perfectly fine to drive with it on.....only a prob if it starts flashing iirc
Think you might find vx dealer closed Monday......its a bank holiday
Mine comes on and off as well....but like Martin....mine runs on lpg too.
Be worth getting the codes read......but prob just a faulty sensor.....theres 2 off them (lambda sensors)
One you can see from the engine bay.....on the exhaust pipe off the manifold (well you can on a 2.2, not sure on V6's) Other one is after the cat and 1st exhaust box ( 1st time i saw the second one today....as my meega had it wheels up in air dangling.....having an oil change)

I gave it a run today alls normal, it does sound like the sensors on the exhaust, looking briefly i found 2 one each side approx under the front seats most of the exhaust is covered with a plate so i'm not sure if there are more, maybe one is faulty.
Does anyone know where i can purchase a diagnostic kit.. it would save alot of time and worry.
Thanks all for your input.

Dave.
