2018-2024 Audi A5 Auto Start Stop Eliminator | Plug & Play
Description
2018-2024 Audi A5 Auto Start Stop Eliminator
Audi’s factory Start/Stop system is intended to reduce engine idling by shutting the engine off automatically during certain stops and restarting it when needed. Audi owner information explains that the Start/Stop system is automatically activated when the ignition is switched on. Drivers who routinely choose the off setting can therefore end up repeating the same A/OFF-button input on future trips.
Automatic Off Preference for the 2018-2024 Audi A5
The Recontrol-X Auto Start Stop Eliminator is built for the 2018-2024 Audi A5 applications shown in the supplied fitment sheet. Once installed, it automatically places the factory Start/Stop function in the off state after startup, removing the need to make that same manual selection each time you begin driving.
The module is not an engine-performance device. It does not tune the ECU, change drive modes, increase power, or serve as a repair for an existing Start/Stop malfunction.
Uses the Existing A/OFF Button Connection
Instead of relying on a software-coding change, this product installs at the physical factory Start/Stop switch. The supplied installation guide shows two panel-release tools being used beneath the center control panel. After the panel is pulled forward, the original A/OFF cable is disconnected and the Recontrol-X harness is connected inline between the button and the vehicle wiring.
The module is shown at approximately 5.70 inches in total length. After the connectors are seated, the compact harness can be positioned behind the panel so the factory appearance is restored when the trim is reinstalled.
Simple Connector-Based Installation
The supplied procedure does not show wire cutting, splicing, soldering, drilling, or ECU programming. It also does not require an OBD-II coding tool as an installation step. The key tasks are accessing the button connector, inserting the harness, making sure the locking tabs click fully into place, and routing the cable where it will not be pinched by the trim.
Take care when releasing the original connector: pull from the connector housing and locking mechanism rather than tugging on the wires themselves.
Factory Start/Stop Control Is Retained
The eliminator changes the default preference after startup but does not remove the factory button. If you want the Start/Stop function active during a specific drive, the original A/OFF switch remains available to change the setting. Reports from owners using this Audi module family also describe continued factory-button operation after installation.
Reversible Without Cutting the Vehicle Harness
Because the module is inserted between existing connectors, it can be removed later. Disconnect the module and reconnect the original factory plug directly to the A/OFF button to return the wiring to its original arrangement. This makes the product suitable for buyers who prefer a removable solution over permanent wire modification.
Check the Vehicle Before Ordering
The supplied fitment data lists 2018 through 2024 Audi A5. It does not separately identify trim, body style, or engine combinations, so those details should not be expanded from outside sources. Verify that your vehicle has the matching factory A/OFF control and compare the button-panel and connector configuration with the product images before purchase.
What to Check Before Checkout
Before purchase, compare the A/OFF control and plug shown in the product images with your A5. Because the fitment sheet does not divide coverage by trim, body style, or engine, the connector check is especially important. Existing Start/Stop fault messages should be diagnosed separately.
For the correctly matched Audi A5, the main value is clear: Start/Stop defaults to the preferred off state after startup, the original button remains usable, installation stays hidden behind the factory panel, and the connector-based harness can be removed without cutting the original wiring.

S&Q
Does this fit every 2018-2024 Audi A5 configuration?
The fitment sheet lists 2018-2024 Audi A5, but it does not separate coverage by trim, body style, or engine. Compare your A/OFF switch and connector with the product images before ordering.
What is the main purpose of the module?
It automatically places the factory Start/Stop system in the off state after startup, reducing the need to press the A/OFF button manually every time you begin a drive.
Where is the module installed?
It installs inline behind the factory A/OFF control panel. The original connector is unplugged from the button and the module is connected between the button and vehicle wiring.
Does installation permanently modify the vehicle wiring?
No wire cutting or splicing is shown in the supplied installation procedure. The module uses plug-in connectors and can be removed later by reconnecting the original factory plug.
Will this repair a Start/Stop warning or malfunction?
No. It is designed to manage the normal Start/Stop preference, not diagnose or repair an existing warning, damaged connector, electrical problem, or Start/Stop system fault.
