A constructive peculiarity of the pillow of all types of checkpoints on Tiguana leads to the appearance of knocking at the roughness. It is released by the pillow itself in contact with the metal. To make sure that she was knocking, it was necessary to open the hood and shake the car from side to side, holding hands behind the front wheels. If it's a CAT pillow case, you have to take it off and put it on a seal in the gap between the moving parts. Replacing the pillow with the new problem will not solve the problem.
