Volkswagen Tiguan Service and Repair Manual: General Information

Caution

The removal and installation of individual steering column switch components must be done in a specified sequence.

WARNING

Before working on electronic system and removing the steering wheel the following conditions must be met:

The technician must discharge static electricity. This is accomplished by touching grounded metal like, for example, water pipes, heating pipes, metal carriers or a heater pipe.

If this note is ignored it can result in failure of the control modules during later operation.

• Remove the battery ground cable.
• Wheels must be located in straight ahead position.

If this note is ignored, it can result in failure of the airbag system during later operation.

Caution

If the universal joint is separated from the steering gear, or the Steering Angle Sensor -G85- is removed, do not perform the following tasks:

• Connecting the battery
• Turning on the ignition
• Turning the steering gear.
• Turning the steering column.

These points must be followed otherwise, it can lead to irreparable damage.

There are two versions of the steering column combination switch components, the steering column electronics control module and the steering column switch mount depending on the manufacturer (Valeo or Kostal). In order to determine which version is installed, check the mounting for the steering column electronics control module on the steering column combination switch.

• Manufacturer Valeo: 3 bolts
• Kostal: 1 screw at the bottom and 2 clips at the top.

Note

• Code the new Electronic Steering Column Lock Control Module -J764- after installing.
• Code the new Steering Column Electronics Control Module -J527- after installing it.
• Additional information: Refer to Owner's Manual.

Malfunction Recognition and Malfunction Indicator:

The Electronic Steering Column Lock Control Module -J764- is equipped with On Board Diagnostics (OBD) which assists in troubleshooting.
