It stores the last stop-start setting you chose, so if you turned start-stop system off on one drive, it stays off the next time you start the engine. It plugs in line with the factory connector named in the instructions, using factory-style plugs on both ends, so nothing is cut or spliced.\u003c\/p\u003e\u003cp\u003eIt does not delete the feature. Turning stop-start back on is the same button press as before, and the module will remember that too.

The switch on the dash can disable it, but only until the key is cycled. This module records the switch position and repeats it after the restart, which is the entire job it does.\u003c\/p\u003e\u003ch2\u003eBattery notes for stop-start vehicles\u003c\/h2\u003e\u003cp\u003eVehicles with stop-start normally use an AGM or EFB battery sized for repeated restarts. If you replace it, use the same type and size, and follow the manufacturer's battery reset or registration step where one exists. A wrong or unregistered battery can leave the stop-start system disabled, and that has nothing to do with this module.\u003c\/p\u003e\u003ch2\u003eConnecting it\u003c\/h2\u003e\u003cp\u003eIt plugs in line with the factory connector named in the instructions, using factory-style plugs on both ends, so nothing is cut or spliced. Because it is plug-in only, removal is the reverse: unplug the module and reconnect the factory connectors directly. Keep the original clips and trim fasteners if you remove a panel to reach the connector.\u003c\/p\u003e\u003ch2\u003eWhere owners notice the difference\u003c\/h2\u003e\u003cp\u003eDrivers usually switch stop-start off for comfort or habit. A restart at every stop is noticeable in a daily driver, the climate system may run at reduced output while the engine is off, and quick moves into traffic feel slower when the engine has to fire first. If those are your reasons, you probably press the button on every drive now. With the module, you press it once.\u003c\/p\u003e\u003ch2\u003eConditions the factory system checks\u003c\/h2\u003e\u003cp\u003eAuto stop needs several conditions at once: a warm engine, enough battery charge, moderate cabin heating or cooling demand, and the vehicle fully stopped with the brake held. If any is missing, the engine keeps running. The module only remembers the button state; the factory controller still decides whether a stop is allowed.\u003c\/p\u003e\u003ch2\u003eTroubleshooting notes\u003c\/h2\u003e\u003cp\u003eIf the setting is not remembered, check that the module was installed with the ignition off and that the connector clicked into place. Then press the factory button once, switch the vehicle off, close the doors, give the electronics time to shut down, and start again. If it still resets, contact support with the year, trim and a photo of the connector.\u003c\/p\u003e\u003ch2\u003eWhat to expect\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eIt does not write anything to the vehicle's modules, and removing it restores the stock default.\u003c\/li\u003e\n\u003cli\u003eIt does not change engine power, transmission shifts, emissions calibration or fuel trims.\u003c\/li\u003e\n\u003cli\u003eIt remembers the last stop-start setting through a key cycle.\u003c\/li\u003e\n\u003cli\u003eIt leaves the factory button working, so you can turn stop-start back on whenever you want.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eConfirm these points\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eModel year and model match a row in the table above (2018–2024 Audi A5).\u003c\/li\u003e\n\u003cli\u003eYour Audi A5 has the factory stop-start button.

Press the button once to switch it off; the module remembers that choice from the next start.\u003c\/p\u003e\u003ch2\u003eWhat sits behind the system\u003c\/h2\u003e\u003cp\u003eVehicles with stop-start are built for many more engine starts than a conventional car. They typically use an AGM (absorbent glass mat) or EFB (enhanced flooded) battery that tolerates frequent cycling, along with a strengthened starter. The memory module does not change any of that hardware. When the battery reaches the end of its life, replace it with the same type and size listed for your vehicle, because a standard flooded battery is not designed for this duty.\u003c\/p\u003e\u003ch2\u003eWhy the factory default is always on\u003c\/h2\u003e\u003cp\u003eUS fuel-economy testing explains the reset. If a stop-start system is non-latching, meaning it switches back on whenever the vehicle is restarted, the EPA measures fuel economy with the system working. If the driver can switch it off permanently, the EPA tests with it both on and off and averages the two, which gives a lower number. Manufacturers therefore make the system come back on at every start, and drivers who prefer it off end up pressing the button each trip.\u003c\/p\u003e\u003ch2\u003eGlossary\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003estart-stop system:\u003c\/strong\u003e Audi's name for the automatic engine stop-start feature on the Audi A5.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey cycle:\u003c\/strong\u003e One switch-off and restart of the vehicle.

The module repeats your last selection at the next start. If you leave it on, it stays on.\u003c\/p\u003e\u003ch3\u003eWhy does my Audi A5 sometimes not auto-stop even when the system is on?\u003c\/h3\u003e\u003cp\u003eThe factory logic checks battery charge, engine temperature, climate load and other inputs. If any are outside range it keeps the engine running. The module does not affect those checks.\u003c\/p\u003e\u003ch3\u003eIs this the same part for every Audi?\u003c\/h3\u003e\u003cp\u003eNo. Connectors and the module that holds the stop-start state differ by platform, so this SKU is matched to the fitment rows on this page. Send the VIN to support if you are unsure.\u003c\/p\u003e\u003ch3\u003eDoes the stop-start button still work after installation on the Audi A5?\u003c\/h3\u003e\u003cp\u003eYes. The factory button works normally. The module simply stores whatever you chose last.\u003c\/p\u003e\u003ch3\u003eDoes my Audi A5 need the factory stop-start button for this to work?\u003c\/h3\u003e\u003cp\u003eYes. The module works with the factory stop-start system and its button. A vehicle built without stop-start has no setting for it to remember.\u003c\/p\u003e\u003ch3\u003eHow does it connect?\u003c\/h3\u003e\u003cp\u003eIt plugs in line with the factory connector named in the instructions, using factory-style plugs on both ends, so nothing is cut or spliced.\u003c\/p\u003e\u003ch3\u003eDoes it change how the battery is charged?\u003c\/h3\u003e\u003cp\u003eNo. Charging is still managed by the vehicle. Stop-start vehicles normally use an AGM or EFB battery built for frequent restarts; replace it with the same type when it wears out.\u003c\/p\u003e\u003ch3\u003eWill it fix a \"stop-start unavailable\" message?\u003c\/h3\u003e\u003cp\u003eNo. That message usually points to the battery or a sensor. Diagnose and repair that first.\u003c\/p\u003e\u003ch3\u003eDoes it change engine power or fuel trims?\u003c\/h3\u003e\u003cp\u003eNo. It does not reprogram the engine or transmission computers. It only stores the stop-start button state.\u003c\/p\u003e\u003ch3\u003eWhat happens if I unplug it?\u003c\/h3\u003e\u003cp\u003eThe vehicle returns to the factory default, with start-stop system switched on at every start.\u003c\/p\u003e\u003ch3\u003eWhy does start-stop system turn itself back on every time?\u003c\/h3\u003e\u003cp\u003eAutomakers set stop-start to default to on at each start. Under EPA test rules, a system that stays off after shutdown is tested both on and off and the results are averaged, which lowers the rated fuel economy, so most systems reset at every key cycle. The module carries your last choice across that reset.\u003c\/p\u003e\u003ch2\u003eOrdering details\u003c\/h2\u003e\u003cp\u003eFree standard shipping covers the contiguous US, with dispatch in 1–2 business days and 3–4 days on the road after that.
