Using torque wrench -VAG 1331-, this page covers repairing ring terminals — Note: penetrating fluid, contact spray or grease are all prohibited, since they cause torque loss on the thread.

Special tools and workshop equipment required

VAG 1331   Note The use of penetrating fluid, contact spray or grease etc. is prohibited since the missing adhesion in the threads may cause a torque excess and, therefore, the break of the threaded connection. The grey sanding pads are suitable for light dirt and "soft surfaces". The red sanding pads are suitable for heavy dirt and "hard surfaces".   WARNING Danger of injury! Observe warning notices and safety regulations → Chapter! –  Disconnect battery.

This could produce a galvanic cell which destroys metal and causes faulty repair.   Note As the thickness of the tin coating may differ according to the design, the cleaning process must be performed step by step and a visual check of the ring terminal is necessary between the steps.

–  Insert adapter into ring terminal and grind off corrosion and dirt with circular movements. –  Check ring terminal and regrind if necessary.

–  If necessary, remove punching burr on ring terminal using the deburrer. –  Tighten ring terminal to specified torque → Current flow diagrams, Electrical fault finding and Fitting locations.   Note Optimum contact is ensured when the components to be secured are tightened to the specified torque after cleaning. –  Apply suitable anti-corrosion treatment to connection → Chapter. –  Reconnect battery.   WARNING Danger of injury! Observe warning notices and safety regulations → Chapter! –  Teach in electric windows again, enter radio code, set clock and, if necessary, recode control units which emit code signals.
