Audi A4 B5 AFN Voltage Problem

Hello everyone,

I have a problem with my A B5 Avant 110PS TDI AFN. Maybe someone here has a tip for me, even though it's not a specific diagnostic problem right now.
The vehicle no longer starts, there are no warning lights illuminated on the dashboard, and nothing electrical seems to be working. However, the battery is not completely discharged, and neither does attaching a jump starter box make any difference. Also, even systems that don't rely on the ignition switch, etc., such as the hazard warning light system, do not function.

Does anyone have a possible solution?

Best regards,

Didi

Hi Didi!

Solution Approach: Use a measuring device to measure voltages!
Start with the battery and, if necessary, locate and fix any interruptions (especially the ground wire!).

Interior locking, ignition switch, or (+) terminal of the power distribution box should be tightened.
To remove the cover under the steering wheel.
