The windshield camera that is responsible for the imaging used for many of the system on the 2016 Touareg is a high failure item and has been constituently backordered from VW. When this camera fails, the advanced systems that were part of this option fail to operate. This includes adaptive cruise control, forward collision warning and automatic emergency braking and lane departure warning. The system does provide warning notifications, but they may occur at any time and there is no confidence the system is working. These notifications overtake other system displays making it difficult or even hazardous to navigate vehicle system menus at times. In addition, this vehicle does not offer standard cruise control, which can accelerate driver fatigue due to the loss of this basic and common feature. The original part on this vehicle is not available used in the USA, or from VW USA. There is a company in Aus that repairs them, but in this particular instance, it appears the repaired unit has failed as well now. This system is very expensive to recalibrate, adding to the expense of the repair, especially without new parts available there is little route to be able to remedy this situation permanently for a safety device that is expected and was an added cost option on this model. Much of the diagnostic work has been performed by myself as I am a Master Automotive Technician.
