Volkswagen Touran Service Manual: Threaded Connections, Repairing
Special tools and workshop equipment
required |
Torque Wrench 1331 5-50Nm -VAG1331- |
 Note
Do not use rust remover, contact spray or grease because the
lack of friction will cause the torque to be exceeded when
installing and this will lead to the threaded connection
breaking. |
The gray sanding pads are for slight contamination and
suitable for "soft surfaces". The red sanding pads are for heavy
contamination and suitable for "hard surfaces". |

WARNING
Risk of injury. Follow all Warnings and Safety
Precautions. Refer to
→ Chapter "Warnings and Safety Precautions". |
|
|
|
|
|
Loosen the cap nut and remove the wiring eyelet from the
threaded connection. |
|
Check the threaded connection for corrosion, contamination,
etc.
|
|
Select the corresponding adapter and the corresponding
sanding pad for the threaded connection. |

Caution
Make sure the tin layer is not worn down too much
and the copper is not visible. A galvanic element can
form from this, destroying the metal and causing
incorrect repairs. |
|
 Note
Due to the different thicknesses of the tin layer, the
cleaning process must be performed in several steps and a visual
inspection of the wiring eyelet between steps is necessary. |
|
|
|
|
Place the adapter on the threaded connection and sand off
the corrosion and contaminants with circular movements. |
|
Check the threaded connection and sand it again if
necessary. |
|
Retighten the connection and, if necessary, the
anti-rotation protection to the specified torque. Refer to
→ Wiring diagrams, Troubleshooting & Component locations. |
 Note
Optimal contact is ensured if the bolted components are
tightened to the specified torque after cleaning. |
|
Apply protection material to the threaded connection. Refer
to
→ Chapter "Protecting". |

WARNING
Risk of injury. Follow all Warnings and Safety
Precautions. Refer to
→ Chapter "Warnings and Safety Precautions". |
|
|
Reprogram the window regulators, enter the radio code, set
the clock and, if necessary, code control modules that have
error messages. |
