Stop vehicle, shift to P, leave engine running.

[Bernieg]

I had the above message on my C220 bluetec a while back and despite following that exact advice the message never went away. Followed all of the recommended remedies. No faults on the alternator, battery connections all fine and I recharged battery with finally replacing the voltage convertor. The car is running fine and always has and all electrics , heaters etc working fine also . However the message on the dash will not go away and comes up as soon as I start the car and remains there for the duration of every journey. I have tried getting reset by a couple of different mechanics using the plug in diagnostic tool but to no avail. How do I reset this warning message? It is driving me to distraction.
Any help would be greatly appreciated. Thanks

These are some possible causes for that error message. The page I got it from (YOUCANIC) even includes troubleshooting tips, but those are far too long to paste here.

• Keeping ignition on with the engine turned off.
• Keeping the radio on but the engine off.
• Leaving the lights on
• Parasitic draw draining the battery when the vehicle is parked
• The battery is no longer holding a charge; test and replace the battery.
• Too many electronic consumers connected to the auxiliary outlets

Wishing you good car health.
