Look for three-stage red LED push-button switches on the door cards or lower dash. A common issue is broken heating wires within the leather seat bolstering, which can be detected if the heating shuts off after a few seconds.
🚨 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.
