If the edc in red is a big problem ..which problem is it? In my Mercedes benz vito 108.

Question edited for a lot more clarity, and add maker.

These are all function of the Body Control Module. You need an auto electrician with a pro grade scan tool computer and access to factory technical bulletins.

I'm assuming you are refering to the EDC light? Do you have any other lights on the dashboard? EDC stands for 'Engine Diesel Control'. This is the electronics for the fuel supply system. First check the silly stuff. Is there plenty of Fuel in the vehicle? (Yes, I've done that!).
When was the Vito given last given a Major Service? Sometimes an old, clogged Fuel filter can cause the light as the electronics is reading a poor fuel supply or water contamination in the filter housing.
Get the filters and fluids changed and see if that helps.

Try the Benz Forums. Sounds like overcharge spike.
