I recently purchased an 08 C300 that was in a minor front end collision. It has several OBD2 codes, all of which are for camshaft position sensor and camshaft actuator and they are all on the side where the damage occurred. What would cause all 3 sensors to show low voltage codes?

 

faulty sensors.

 

There's a sticky in this forum about the Balance Shaft causing issues and causing camshaft codes to be thrown. It was improved on the later M272 engines but was still an issue for the 2008 models
