7840414 BMW M3 E90 E92 M5 E60 EDC-K Damper Control Module – OEM Used & Tested

Opis

This BMW EDC-K damper control module is a genuine OEM electronic component for BMW M3 E90 E92 and M5 E60 models. Primary OEM number 7840414. It is designed to control the Electronic Damper Control system with continuous adjustment, known as EDC-K, by regulating the damping force of the electronically adjustable shock absorbers according to the driving situation and the selected mode. It is a key part of the dynamic chassis concept of these performance models.

Its job is to collect signals such as vehicle speed and body movement, calculate the required damping level for each wheel and drive the damper actuators accordingly. It also monitors the system and stores a fault when a sensor or actuator fails. A properly working EDC-K damper control module supports stable handling, good ride comfort and correct operation of the adaptive suspension system.

Common signs of a faulty unit include an EDC or suspension warning in the instrument cluster, a ride that feels unusually harsh or floaty, dampers that stay in one fixed setting, no change in damping when the mode is switched, or the system dropping into a fail-safe mode. When the module fails, the suspension may lose its adaptive behavior and the vehicle may feel less stable and less comfortable than normal.

This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 7840414 before ordering. Professional installation is recommended, and coding or programming of the module to the vehicle may be required where applicable.
