Below is the photo of the tube going from the engine head to the brake cylinder. The pipe cracked in 3 places, due to bad quality of the plastic material. And no, it's not rubber.
This pipe creates vacuum in the brake cylinder to make car brakes work. If the pipe breaks, the vacuum will not be sufficient enough to stop the car.
Luckily, I caught this before leaving the garage, and replaced it with the $1.50 tube from our local Autozone. 10 minute of work saved lives..
While I may buy a VW in the future, I will never buy a VW from Mexico.
