Check Engine Light Due to Faulty Camshaft Adjuster Solenoid on Mercedes-Benz CLK550

The camshaft adjuster solenoid (which is related to the variable valve timing system) may fail or timing chain/balance shaft components may wear, resulting in illumination of the Check Engine Light and various drivability issues. Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.

problem details
Check engine light comes on and off. I had it checked while getting oil changed. They said problem with camshaaft left/right. They thought it was a recall. Does any know if this is a recall. How much does it cost to fix?

same situation, took car in for AC repair and they want $600 to replace all four sensors because two are faulty.

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.
