Fitment guarantee and VIN verification

Each control unit undergoes verification of the electrical connector condition, checking for mechanical housing damage, and inspection of the signal pins.

Fitment tip: Airbag control units in the VAG group are selected strictly by the part number and letter index (suffix K). After installation, the module may require coding / programming into the vehicle system (component protection). Before purchase, we recommend comparing the OE number with your old module or verifying fitment using the vehicle's VIN.
