W220 Gear Lever

The Electronic Selector Lever Module (ESM / Module N15/5) on the Mercedes-Benz S-Class (W220) is notorious for a structural flaw that leaves the vehicle completely stranded. It features a critical design point where a tiny, cheap component can disable an otherwise pristine luxury sedan.The entire shifter assembly is not just a mechanical linkage, but an anti-theft control module tied directly to the car’s Drive Authorization System (DAS) via the CAN bus.
