Gear Shift Micro Switch This is a documented issue recalled for VW and Audi vehicles between 2015-2019. VW recalled all and still is fixing the issue in cars from those years, yet AUDI decided to just offer an extended warranty to those cars for that specific issue. Who is responsible VW or AUDI.

This is dangerous. There has been a recall issued in june 2018 on 140k Audi cars with similar problem, my model has yet to be included, and there are likely more cars with similar malfunction.
1. What component or system failed or malfunctioned, and is it available for inspection upon request? The component that malfunctioned was with the electrical system. It was the Shift Lever Microswitch. It is not available for inspection because the car has been repaired. 2. How was the safety or safety of others put at risk? There was a build-up of silicate on…
