ABS Control Module -J104-, ATTACHING TO ABS Hydraulic Unit -N55- (MARK 70 ABS/ASR): Installing

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.

Assembly is performed in reverse order. Note the following:

WARNING: Excessive shaking (for example, dropping, impact) can damage the ABS Control Module -J104-. Do not use the ABS Control Module -J104- again if this happens.
NOTE:

A new ABS Control Module -J104- can be installed on an old ABS Hydraulic Unit -N55- maximum twice. This assures the elastic seal will not leak.

A used ABS Control Module -J104- may not be installed a second time.

-- Slide all sealing rings -A- slightly over the valve dome.
