For vehicles with a combined fog light and marker light, check whether the lower edge of the headlight is lower than 350 mm above the ground. If this is the case, additional marker lights must be installed above this dimension. The standard marker lights must then be deactivated by removing the light bulb and loosening the cable connection. Due to the use of gas pressure technology in the B6 / B8 dampers, the level of lowering may vary slightly depending on the vehicle. In vehicles with electronic damping systems, the functionality of the damper adjustment is no longer applicable when B12 chassis is installed. - If available, we recommend using Pro-Tronic to avoid error messages. For vehicles with electronically adjustable dampers (standard equipment). PRO-TRONIC suppresses the error messa.
