BODENLA Auto Start Stop Eliminator for Audi A4/S4/A5/Q5 (2017–2024) — Plug‑in A‑OFF Memory, No ECU Reflash

The BODENLA Auto Start Stop Eliminator permanently sets your Audi's A-OFF to stay active after each restart, removing the need to manually disable start/stop every time.

If you own a 2017–2024 Audi A4 or S4, or a 2018–2024 A5, Q5 or SQ5, this compact cable plug-in replaces the repeated hassle of pressing the A-OFF button after engine start. Designed as a simple inline harness with no internal modules or energy storage, it preserves factory electronics and avoids fault codes. The kit includes the eliminator cable and basic trim tools so you can install it yourself with minimal effort.

How does this eliminator change daily driving?

Once fitted the cable tells the car to remember the A-OFF setting so the auto start/stop remains disabled after every ignition cycle. You still retain full manual control: pressing the A-OFF button will re-enable the car’s default start/stop behaviour when desired. The change is seamless and reversible without software reprogramming.

• Automatically keeps A-OFF active after each restart
• Manual A-OFF button continues to function normally
• No ECU reflashing or dealer tools required
• Reversible by removing the cable or pressing A-OFF to reactivate

Is installation difficult and what tools are included?

Installation is straightforward for anyone comfortable removing the center control panel. The package supplies disassembly tools and a clear wiring orientation to plug the harness into the factory socket. Expect to start the car during the process so the unit can set the default state — the A-OFF light turns red within seconds after installation.

• Includes the eliminator cable and basic trim removal tools
• Requires removal of the center console panel to access the socket
• Plug-in connection — no soldering or splicing
• A-OFF indicator will confirm correct installation (light change in 3–5 seconds)

Will this cause errors or affect my vehicle electronics?

The BODENLA cable contains no active modules or stored-energy components and is engineered to preserve factory signalling logic. That means no diagnostic trouble codes (DTCs) are introduced by installation, and the vehicle’s electrical system remains unaffected. It operates as a passive override that only changes the remembered A-OFF state.

• No internal module or energy storage inside the harness
• Designed to avoid fault codes and maintain factory wiring integrity
• Non-invasive — reverses by unplugging the cable
• Works through the existing OEM socket and connectors
