WARNING: This page is about a different car, the 2016 Volkswagen Beetle, 2015 Volkswagen Beetle, 2014 Volkswagen Beetle, and 2013 Volkswagen Beetle. However, it is still accessible from the selected car via links, so may be relevant.

Install in reverse order of removal. Note the following:

CAUTION: Do not confuse the brake lines when connecting them to the ABS Hydraulic Unit -N55-. Mark the lines in their installed position before removing them.

NOTE:

Remove the plugs on the new ABS Hydraulic Unit -N55- only when installing the corresponding brake line.

Brake fluid will leak out if the plugs are removed too early from the ABS Hydraulic Unit -N55-. The system will then not have sufficient brake fluid and will not adequately bled.

WARNING: When installing the mount, make sure the rubber insulation does not push out of the bracket. Make sure the ABS Hydraulic Unit -N55- is secure after installing it otherwise malfunctions can occur.

-- Make sure the rubber buffers fit correctly in the mounts when installing the engine cover.
