Hey fellow Benz enthusiast and owners. Anyone with hybrid mercedes benz encountered such issue before?

The main warning message displayed on the dashboard is “Malfunction” accompanied by a yellow gear icon.

The problem usually occurs when the car is cold, especially in the morning. During low-speed maneuvering, particularly when shifting between Drive and Reverse, the vehicle may jerk slightly or move unexpectedly while reversing even without pressing the accelerator. Shortly after that, the malfunction warning appears, and in some cases the engine shuts off completely.

I scanned the vehicle and occasionally received fault code: P060600 (CP48)

So far i have changed transmission oil, software update, 12V battery and auxiliary battery change but problem still exist. Should i change TCU? Or is there anythinf else that needs to be checked like wiring, and alternator?

Hi everyone, I’ve been getting a malfunction warning on my dashboard for a while now. The issue usually occurs when the car is cold in the morning. When I shift from Drive (D) to Reverse (R) while maneuvering, the car sometimes jerks or slightly accelerates on its own while reversing—even when I’m not pressing the gas. Shortly after, the malfunction warning appears, and in some cases, the engine even shuts off.

When I scanned it, I got error code P060600 (CP48), but the code doesn’t show up consistently.

So far, I’ve replaced the 12V battery, changed the transmission oil, and had the software updated at the dealership, but the problem persists.

Has anyone experienced something similar or have any idea what might be causing this?
