Mercedes Benz W222 W217 W205 TAILGATE CONTROL MODULE UNIT A2229006008 – Original Used Part

Diagnosis and Common Symptoms

The Tailgate Control Module (A2229006008) is a critical component in the Mercedes-Benz electronic architecture, managing the motorized actuation and soft-close synchronization of the trunk. Failure often stems from voltage spikes or moisture ingress within the rear cavity. On a STAR or Xentry diagnostic scanner, you will typically find fault codes such as B142F (Internal fault in control unit) or communication errors on the CAN-B bus. Common symptoms include the tailgate failing to respond to the remote key fob, the trunk lid stopping mid-travel, or the latch failing to pull the lid into the final locked position. If your tailgate button is illuminated but the motor remains silent, this module is the primary suspect.
