    The check engine light illuminated. An OBD reader confirmed a problem with the Secondary Air Injection System. I also noticed a loud roaring type noise for the first two minutes after vehicle starting. The problem was traced to a failed Secondary Air Injection Air Pump. Dealer wanted $1,300 to replace. I sourced a Bosch pump for the application and replaced it myself for around $450.

    My yellow engine monitoring light came on, the car was going back to Uk ( from Italy ) for it's annual service. Called mercedes they said it should be ok for trip, car ran beautifully smooth like a new car. But when I arrived at service garage after driving 1000 miles I was told it's the secondary fuel injection pump, part cost £999 :( can these be reconditioned :)

    My "visit workshop" light came on. Drove it to dealer and(of course) light would not come on. As I drove away it came back on. Dealer said it was probably the shocks or something with the "sports model". After driving it several more miles the RED: DO NOT DRIVE VEHICLE TOO LOW" came on. I pressed the button that says "Vehicle rising" light went off and just as I made it home, came on again. The car won't rise up, and the air suspension noise it makes doesn't make the noise anymore. What is this? Is there a shop in Santa Barbara that won't charge for diagnosing the problem?
