Full details
Tired of pressing the A-OFF button every time you start your BMW? The M-Tech Start-Stop Eliminator plugs in behind the start-stop button and switches auto start-stop off for you, every drive.
Why not just code it? Coding start-stop off usually means paying a specialist or buying a coding tool, and a software or OTA update can reset it so you pay again. It also rewrites settings in your car's software. This module is plug-in hardware: no coding, no software changes, it keeps working after updates, and it unplugs in seconds to return your car to factory before a service.
- Off by default: start-stop is switched off automatically each time you start the car.
- Dual mode with memory: run it off-by-default, or have it remember your last setting.
- Your button still works: press A-OFF any time to turn start-stop back on.
- Plug & play: original-style plugs fit between the button and its connector. No cutting, no splicing, no coding.
- Fully reversible: unplug it and the car is back to factory.
- Install tools included: trim tool and hex key in the box.

Why not just code it?
Every time you start your BMW, auto start-stop switches back on. Coding it off works, but it costs money, it can be undone by the next software update, and it changes your car's software. This module does the same job without any of that.
No coding bill
Coding start-stop off usually means paying a specialist or buying a coding cable and app. This is a one-off plug-in part.
Survives updates
Software updates and dealer visits can reset coding. The module is hardware, so it keeps working after an update.
Software changes
Nothing is written to your car's computers. Unplug it before a service and the car is exactly as it left the factory.
Plug & play
No laptop, no cables, no risk of a failed coding session. Pop the trim, plug it in, done.
Warranty decisions are up to your dealer. Because the module makes no software changes and unplugs in seconds, you can always return the car to factory condition before a service.
Before or after?
Every red light, the engine cuts out. Every green light, it shudders back to life.
- Engine stops at every light
- Restart delay when traffic moves
- Press A-OFF every single drive
Start-stop is off the moment you start the car. The engine idles smoothly, just like you want.
- Start-stop off automatically
- No restart delay at green lights
- Turn it back on with A-OFF any time
Illustration. Your car's own button still works as normal.

Questions, answered
Everything people ask before ordering the Start-Stop Eliminator.
Q1 Which version do I need, F or G series?
Pick G-Series for G-chassis BMWs (wide connector, e.g. G20, G30, G05) or F-Series for F-chassis BMWs (small 4-pin plug, e.g. F30, F10, F15). It suits BMWs with an A-OFF start-stop button: 1 to 8 Series, X1 to X7, Z4 and M2. Not sure? Send us your VIN and we will confirm before you order.
Q2 Why not just code start-stop off?
Coding works, but it usually means paying a specialist or buying a coding tool, and a software or OTA update can reset it so you pay again. It also rewrites settings in your car's software. The M-Tech module is plug-in hardware: no coding, nothing changed in the software, it keeps working after updates, and you can unplug it in seconds to return the car to factory.
Q3 How do I find my model year?
Look at the 10th character of your VIN (on your registration document, the windscreen corner or the door frame). For example J = 2018, K = 2019, L = 2020, M = 2021, N = 2022, P = 2023.
Q4 Do I need to cut wires or code the car?
No. It plugs in between the start-stop button and its original connector. No cutting, splicing or coding.
Q5 Can I still turn start-stop on?
Yes. Your A-OFF button works as normal, so you can switch start-stop back on whenever you like.
Q6 What is dual mode?
You can run it off-by-default (start-stop is off every time you start the car) or memory mode (the car remembers the last setting you chose).
Q7 Will it cause fault codes or affect my warranty?
It is designed to work with the car's original signals and leaves no trace, and you can unplug it at any time to return to factory. If you are worried about your warranty, check with your dealer.
Q8 Does it drain the battery?
No. Standby current is 0 mA.
Q9 Shipping and returns?
