Why is my vw Tiguan parking sensors not working?

Your VW Tiguan parking sensors not working are most likely caused by faulty parking sensors. Listen to see if there is a buzzing sound. If there is, then the sensor itself is working. If You cannot hear anything or if You do not want to put Your ear that close to the sensor then You can simply put Your finger up against it. If the sensor is vibrating juSTSlightly, then there's no need to replace it.One of the best things that You can do for Your sensors is keep them clean. Most of the time, whenever there are any issues with the reverse parking sensor, it is because gunk from driving has settled over it. You will find that the best way to do this is to simply take out the sensors and clean them with a soft cloth or rag.
