Find experienced local auto electricians in Los Angeles

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.

Need help repairing electrical wiring issues on my Ford Bronco. The main issue is that the headlights do not work at all, even after replacing bulbs and checking basic fixes. However, all other lights work fine including parking lights, brake lights, turn signals, rear lights, and interior electrical components. The issue appears to be related to the headlight wiring, switch, relay, ground, connector, or harness, and I need someone experienced with older Ford electrical systems to properly trace and repair the problem. I also need help fixing the rear tailgate window switch wiring. The rear window motor itself works, but the switch/wiring connection is not functioning correctly and may need rewiring or troubleshooting. Looking for someone comfortable with automotive electrical work who has their own tools/wiring/multimeter and can properly fix wiring 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.
