Research showed this is common factory defect with these engines since mercedes used soft metal for the sprockets causing premature wear. I contacted mercedes and they told me there is no open recall or class action suit for this year/model and recommended the car be towed to a mercedes dealership for evaluation. …”

“1.8l 4 cylinder supercharged. Teeth on cam gears broken off and worn down to the point of the vehicle jumping timing. And damaging valves and other major components.

Reason for this happening is due to mercedes using a thin bicycle like chain for timing. Stretches beyond safe limits in 50k of miles. Loose chain eventually breaks and/or damages cam gear teeth and other components. …”
