My pride and joy - 2010 Roadster - has developed an intermittent fault which causes the engine warning light to come on. Currently I am told this is triggered to register out of range readings from the lamda sensors - but there are no other symptoms and the car appears to run fine. If reset, the fault occurs again fairly soon (like within 50 miles). This is a new car with still under 1,000 miles on the clock. I am told there is a known problem for which the factory are seeking a solution - and in the meanwhile not to be too concerned !!! Any experience of this out there?
