WARNING: This page is about a different car, the 2025 Volkswagen Jetta. However, it is still accessible from the selected car via links, so may be relevant.
Connect electric welder ground (GND) connector directly to the piece to be welded. When doing so, be careful that there are no electrically insulated parts located between the ground connection and the welding location.
Do not touch electronic control modules and electrical wires with the ground connection or welding electrode.
Replacing electronic control modules after a collision is only required if at least one of the following conditions is met:
- The housing is distinguishably deformed or damaged.
- The contact surface or bracket is deformed; the device shows no damage on the outside.
- The connector is damaged or corroded by moisture.
- The function test or OBD of the device shows the fault: "Control module faulty".
If electronic components, for example the ABS control modules, are removed for repair work and then reinstalled, then they must be checked for function according to available information after assembly, using OBD, for example.
