Trunk latch won’t open with the remote

Hi, I recently had my 2006 Audi A4 inspected because the OBD system won’t communicate and scanners keep showing a link error. The shop diagnosed it as a K-line communication issue, likely wiring damage or a module pulling the signal down, but they weren’t able to fix it. I’m looking for someone experienced with Audi/electrical diagnostics who can trace and repair the issue. If this is something you think you can help with, please let me know. Thanks! Official diagnosis below: Findings: • OBD scanner shows “link error” (no communication) • Verified power and ground at OBD port • Tested Pin 7 (K-line communication wire): reading ~0.1V (should be ~10–12V) → Indicates communication line is being pulled low or shorted Actions performed: • Checked and isolated common causes of K-line interference: • Radio circuit • ABS system • Related fuses • No change after isolating these components Conclusion: There is a fault in the K-line communication circuit, likely due to wiring damage or a module pulling the signal down. This prevents communication with the vehicle’s control modules and blocks proper diagnostics. Recommendation: The K-line issue must be resolved first. This requires electrical/wiring diagnosis, which is a specialized process involving tracing the communication line through the vehicle. I recommend consulting a technician or shop that specializes in automotive electrical diagnostics and wiring repair. Once communication is restored, I can proceed with full diagnostics, identify the cause of the warning lights, and complete any necessary repairs.

The battery is charged but power is not getting to the wheels. For awhile, cables would work and offer full power, but apparently shake loose. Now I cannot reconnect the cables to maintain power.

My Nissan Murano hss an electric issue. If the vehicle is not started every other day, it will not start, unless given a jump start. The battery is not the issue.

My Audi a4 needs electrical work done so that it can run. I had another mechanic lol at it and he did some work so I just need it diagnosed and fixed so that I can be able to crank and start.

So basically my car was running fine yesterday but when I want to start it today the headlights were flicking off an on while car was off. When I started the car the engine ran for approximately 2 seconds before dying out and leaving everything else on and running still. I tried multiple times, tried to get it jumped, and theres a weird clicking noise in my fuse terminal by the steering wheel. I also tried swapping some relays, It just got the battery replaced and a new bcm a month ago maybe. Could not be adapting well or maybe a fault wire, but still something I cant handle

Car has 133,000+ miles. Related parts need to be included. Mounts, buffers, bump stops, nuts and bolts. I am open to reliable non OEM parts to bring the cost down. Only interested in mechanic that has the required Audi tools to complete the job reliably. Let me know if you have done similar in the past.
