是的，先换Camshaft Position Sensor， 不贵

For the M272 V6 engine used in the 2010 GLK350, this code typically stems from the following:

• Faulty Camshaft Position Sensor or Magnet: This is the most common and least expensive fix. These sensors or the "magnets" (solenoids) that control them frequently fail.
• Dirty or Low Engine Oil: The variable valve timing (VVT) system relies on oil pressure to adjust timing. Sludgy or low oil can prevent the solenoids from moving correctly.
