Known Issues for This Vehicle
Oil leaks
In-line engines, like the M260, can sometimes experience oil leaks due to gasket or seal failures, which might be exacerbated by the direct fuel injection system's higher pressures.
Carbon buildup
Direct Fuel Injection (DFI) engines are prone to carbon buildup on intake valves because the fuel does not wash over the valves, leading to performance issues over time.
Turbocharger issues
The M260 engine may suffer from turbocharger problems, such as boost leaks or turbo failure, which can affect engine performance.
Timing chain tensioner problems
Some Mercedes-Benz engines have been known to experience issues with the timing chain tensioner, which can lead to a noisy engine or even engine damage if not addressed.
Faulty camshaft adjuster solenoids
These components can fail, leading to rough idling, poor acceleration, or engine misfires, and are a known concern in some Mercedes-Benz engines.
