Fitment guarantee and VIN verification

Each panel undergoes data bus communication diagnostics, touch field testing, LED backlight verification, and haptic motor check before being prepared for shipping.

Fitment / installation tip: The initial designation 4K0 (group of indicators and controls 919) with index B defines the digital touch module dedicated to the extended 4-zone climate control system of the C8 / 4K platform. This panel is sometimes mechanically damaged by rear passengers (cracking of the glass surface from a strike with a shoe or bag) or flooded with drinks left on the rear seat. This results in no response to touch, flashing LCD segments, failure of the rear seat heating, or LIN bus errors in the climate control unit. The original OEM module connects to the factory multi-pin connector, ensuring full software compatibility and trouble-free communication. Before purchase, we recommend comparing the OE number stamped on the rear housing of the module or verifying it using the vehicle's VIN for the PR-9AQ equipment code.
