    You have a very rich running car, most likely you have a check engine light on too, yes? Have your car inspected by a good German car shop ASAP.

    Thank you for your response to the comment I wrote in Oct. Coincidentally, I put my Mercedes SL500 in a German shop as you suggested because the " check engine light " recently came on . Have spent over 5 grand in less than a year. Love the car but seriously considering whether to buy an ESA or trade it in .
