Hi

I recently services my MB S 500, the engine diagnostic lamp was lit for a long time, but never had any trouble. in the service they said its due to emission control air injection is failed and need to be replace, they charged 663£ for the part (total bill was 1700£ including A service and front bumpers).

Now just within a month again the same engine diagnostic lamp is lit, i have booked a appointment with the same MB service heathrow.

Sorry to say I have no knowledge on the car technical stuff, Could some one pls throw some lite what is the exact problem?

And there is no error codes shown.
