I frequently repair Mercedes-Benz engines, especially the 272 model. The error code for right exhaust camshaft retardation is quite common, which means the component controlling the opening and closing of the right exhaust valves is running slower and can't keep up with the rhythm. There could be several possible causes: the engine timing chain or belt is loose or worn out, or the adjustment module in the variable valve timing system is stuck or leaking oil; sometimes, poor contact in the sensor wiring can also trigger false alarms. Symptoms usually include the engine warning light on the dashboard, feeling a lack of power while driving, sluggish acceleration, and increased noise. It must be addressed promptly; otherwise, a skipped tooth in the chain could damage the entire engine's internal components, leading to costly major repairs. The general approach is to visit a professional shop to confirm the issue with a diagnostic tool first, then replace the worn parts or clean the system accordingly. It's recommended to check the chain tension every two years.
