Code indicates that the mixture in bank 1 is too rich. It can result from faulty: MAS sensor, fuel injectors, oxygen sensors, incorrect fuel pressure. Also, exhaust gas leaks can create this problem. The Mercedes Benz fuel system is complex, be sure that anyone, other than the dealer/properly trained mechanic, knows what he is doing to avoid bigger head aches.
