Volkswagen Tiguan Service and Repair Manual: Windshield Wiper System

General Information

Caution

Always follow the procedure as described in the Repair Manual when disconnecting and connecting the battery.

Note

Additional information:

• Refer to the Owner's Manual.
• Refer to Self Study Program; No 404; The Tiguan.

The Wiper Motor Control Module -J400- is integrated with the Windshield Wiper Motor -V-. If the Wiper Motor Control Module -J400- is to be exchanged, read the coding beforehand and then code the new Wiper Motor Control Module -J400- with this value.

To remove wiper blades, wiper arms must be put into "service/winter position". The "service/winter position" is activated by pressing the windshield wiper lever in the "one-touch wiping" position within 10 seconds after switching the ignition off Owner's Manual.

Malfunction Recognition and Malfunction Indicator:

The Vehicle Electrical System Control Module -J519- is equipped with On Board Diagnostics (OBD) which assists troubleshooting.

Use the Vehicle Diagnostic Tester in "Guided Fault Finding".

Windshield Wiper Motor, Deactivating Alternating Park Position Function

Windshield wiper system is equipped with APP function (alternating park position).

The APP function causes the wiper, after every second time it is switched off, to move up one level after reaching the lowest position.

To install the wiper arm on the linkage, the motor must be switched off in the lower park position. This is attained by deactivating the APP function (code Wiper Motor Control Module -J400-) using the Vehicle Diagnostic Tester.

Note

• An activation of APP function is not possible.
• APP function is automatically activated after 100 wiping cycles. This applies to wiper motors in which the APP function was deactivated as well as for new wiper motors.

Rain/Light Recognition Sensor -G397-

Rain/Light Recognition Sensor -G397-, Removing and Installing

The rain/light recognition sensor is designed so that it can be used again. The only requirement to use it again is that the connecting pad must not be damaged.

Caution

Store the removed Rain/Light Recognition Sensor -G397- is in a dust-free area and keep the silicone connecting pads from getting dirty.

Note

• If the rain sensor was replaced by another rain sensor having a different part number, it is necessary to code the new rain sensor.
• Rain sensors cannot be interchanged. Refer to the Parts Catalog for the correct rain sensor.

Removing

• Switch off the ignition and all electrical consumers and remove the ignition key.
• Remove the interior rearview mirror.
• Disconnect the connector -A- from the Rain/Light Recognition Sensor -G397--1-.

• Pry the Rain/Light Recognition Sensor -G397--1- by the opening -3- out of the retaining plate -2- carefully using a screwdriver.

Note

During removal, pry off the complete Rain/Light Recognition Sensor -G397- and not just the upper shell of the sensor.

Installing

Install in reverse order of removal. Note the following:

Caution

• Always clean the windshield surface inside the Rain/Light Recognition Sensor -G397- bracket before installing. Remove any traces of the connecting pad still remaining on the windshield.
• Surface (connecting pads) of Rain/Light Recognition Sensor -G397- must not be contaminated or damaged when installing. Always replace a sensor that has a damaged connecting pad.

Note

If the surface (connecting pads) of Rain/Light Recognition Sensor -G397- is soiled, it can be potentially cleaned by "applying" and then "pulling off" one or more adhesive strips.

• Clean the windshield thoroughly around the retaining plate, cleaning solution.
• Remove the cap from the new Rain/Light Recognition Sensor -G397-, if necessary.
• Insert the Rain/Light Recognition Sensor -G397--1- into the retaining plate on the windshield -2- and then press it in securely.

Note

Even if the sensor is installed correctly, small air bubbles can form between the windshield and the connecting pad. The contact surface must be free-of-bubbles after approximately 10 minutes.

• Connect the connector -A- and then install a wire cover to secure the rain sensor.
• Install the interior rearview mirror.
• Code the Rain/Light Recognition Sensor -G397-, if necessary.

Rain/Light Recognition Sensor -G397-, Servicing, Manufacturer TRW

Only TRW can replace the housing and optical unit if the optical unit (coupling cushion) is damaged.

There are different housings for the rain sensors because there are multiple manufacturers.

A replacement rain sensor housing and optical unit are always delivered with mounting clips. Remove these clips if they are not needed.

Perform the Following

• Remove the rain sensor.

Caution

The rain sensor electronics may be damaged.

Be careful not to insert the screwdriver all the way through the housing up to the rain sensor electronics.

Do not touch the rain sensor electronics.

• Press the tab -2- on both sides and separate the upper section -1- with optical unit from the lower section -3-.
• Remove the rain sensor electronics at the connector -4- from the old lower section and install the new electronics the exact same way.

Caution

Do not touch the optical unit.

Remove the protective cover from the rain sensor just before installing it.

• Assemble the new housing upper section with optical unit and protective cover with the housing lower section.
• Install the rain sensor.

Rain/Light Recognition Sensor -G397-, Coding

• Code the Rain/Light Recognition Sensor -G397- using the Vehicle Diagnostic Tester.
