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.

When repairing wires with a cross-section up to 0.35 mm2 , new contacts must always be crimped on using the Crimping Pliers - JPT VAS 1978/9A or the Wiring Harness Repair - Crimping Plier - Base Tool VAS 1978/1-2 with the Wiring Harness Repair Set - Crimping Head - JPT VAS 1978/9-1 installed. Due to the low current strengths of these wires in the micro- to milli- range, contacts crimped on incorrectly lead to continuity resistances and cause malfunctions or failure of the respective system. The most frequent applications of these contacts are:

By using the Crimping Pliers - JPT VAS 1978/9A or the Wiring Harness Repair - Crimping Plier - Base Tool VAS 1978/1-2 with the Wiring Harness Repair Set - Crimping Head - JPT VAS 1978/9-1 installed, the correct connection between crimp contact, wire and single wire seal is guaranteed. The tool is to be used only for the purpose described.

NOTE:

Contacts in a normal and a gold-plated version are crimped onto repair wires. The same version of the contact that was installed at the factory must always be used for repairs.

-- Crimp the contact, wire and single wire seal by completely closing the Wiring Harness Repair - Crimping Plier - Base Tool VAS 1978/1-2.

-- Reopen the Wiring Harness Repair - Crimping Plier - Base Tool VAS 1978/1-2 and remove the finished crimped-on contact.

A correctly performed crimp is distinguished by a clean compression of wire and single wire seal in the contact and has an impression on the rear side which identifies that the crimp was performed by a professional using the correct tool.
