Used Car Buyer Checklist: Code 889
Keyless-Go enables unlocking by grabbing the door handles and starting the engine with a push-button. Check for chrome trim inserts on the door handle faces. Make sure all four handles lock/unlock correctly, as moisture intrusion often breaks individual handle sensors.
🚨 Avoid Retrofit Frauds:Always decode the VIN configuration rather than relying on visual trims. Sellers frequently install visual replicas (such as speaker covers or AMG body panels) on standard vehicles to charge a premium. A genuine datacard decode matches the vehicle's manufacturing specifications on the day it rolled off the assembly line.
