OVERVIEW
Restore the battery ground connection
Genuine VW/Audi 5C0-971-235-B connects the negative battery terminal to the assigned vehicle ground point. A sound connection provides the return path needed by the starting, charging and electrical systems.
The cable assembly includes the battery terminal clamp, insulated conductor and ground attachment terminal shown in the archive photo. Match the original routing and connections, especially where battery monitoring equipment or Start/Stop changes the cable arrangement.
Technical details
- Complete factory number: 5C0-971-235-B.
- Factory specification: conventional negative battery cable, factory number 5C0-971-235-B.
- Design: insulated cable assembly with a battery post clamp and mounting-eye ground terminal.
- Quantity supplied: one individual negative battery cable assembly; battery, ground fastener and other cables are separate.
This cable is assigned to the conventional battery installation without Start/Stop. It is separate from the positive cable and from any additional engine-to-body ground strap. Do not substitute it for a different cable arrangement solely because the terminals appear similar.
Common reasons to replace
- Corrosion has damaged the terminal, conductor or ground connection.
- The cable insulation, crimp or mounting terminal is physically damaged.
- Voltage-drop testing identifies excessive resistance in the cable assembly.
Check the battery condition, terminal contact and body ground surface before replacing the cable. Slow cranking or charging faults can have several causes; a measured circuit test helps distinguish a cable problem from a battery, starter or alternator fault.
