Start/Stop Voltage Stabiliser – Mercedes-Benz EQV, EQC & More
This 12 V voltage stabiliser is a black plastic unit with three connections.
The stabiliser keeps the 12 V supply steady for the electronics. A faulty unit can cause flickering lights, warning lights and electrical faults. Check the 12 V battery condition, as a weak battery can cause similar faults. Some faults may need a diagnostic check to confirm. Electric vehicles still rely on a 12 V system for lights, locks and control units. Keep the connectors clean and dry when fitting. The specifications below show the size and type, so you can compare them with your old part before ordering. The fitment table lists every electric version the bilstein group parts finder shows for this part, with its power output.
