Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.

Cam magnets replaced twice under warranty. Check engine light came on last month (out of warranty) Took it in. They said cam magnets bad again, want $600 to repair. I said hell no. Now a month later, car not starting; like it is starving for fuel. But when it finally starts, no check engine light.
The check engine light has been on so much on this car, that it is probably burned out. This is my first and last MB. Have had 6 BMWs with no issues like this car. - Visitor
