Disable Auto Start/Stop- $60 and 15 minutes

[C-12]

For all those looking for a permanent method of disabling auto start/stop:


I purchased a memory module which remembers the last input of the auto start/stop function. Ebay seller aa.cars2012. Item shipped from Australia. Shipping took approximately 3 weeks and with today’s conversion rates, this will cost approximately $60 U.S. Dollars.


Installation:

1. The seller ships the module along with 2 metal keys. These slide into hidden slots on the control panel enabling the panel to pull straight out.





2. Disconnect harness from rear of control panel.


3. You will notice the female end of the supplied harness does not match up perfectly with the male end on the car.



4. I used a razor blade and cut two of the top corners out of the supplied harness (female end). This allowed the supplied harness to connect to the car harness.




5. Push and slide the control panel back into place and you are done.


I have had this installed for about 1 month and has worked flawlessly. I no longer need to push the auto start/stop button every time I start the car or have the A/C running if using VCDS mods.

Or buy a carista ($15), open the app and select disable start stop.

Much easier and cheaper.

Also, you don't need AC running using the Carista method.

I thought Carista still doesn't have a method for the B9 platform?
At least that's what it states on the website.

"Audi MLBevo cars (incl. A4 B9, A6 C8 and derivatives)
Here things get a tad more interesting. VAG doesn’t give us a method to easily achieve total start/stop system deactivation, as with MLB-platform cars. This creates the need for us to get a bit more creative as to how we achieve that — we need to “trick” the car into thinking that the appropriate conditions for normal start/stop operation are not met. We do that via a well-documented coding in the car’s HVAC (Heater, Ventilation & Air Conditioning) ECU. This does introduce a slight inconvenience, though: if you were to completely turn off your car’s air conditioning, the start/stop system will start working again. It’s an unfortunate circumstance resulting from the method we use. That being said, we’re still looking at improving this, though due to the nature of the car manufacturers themselves, we’re unable to give out any promises as to whether this will ever change or not. The setting itself is located in setting category Other and is called Auto start/stop system (if equipped) on these cars."

Wait, so with Carista you dont need the AC running? Are you sure?

I’m sure, did it in my car the day I got it.

Confirmed with Carista that the A/C system must be running for the auto start/stop system to function. I will update my original post to include this info.

[Kondax]

That's bizarre then. I don't run the AC but mine stays off. Then again, I've fiddled with it using VCDS before.

Looks like I’ll be purchasing the module. Thanks for sharing!

Why doesn’t the harness fit without modification?

[icon5585]

Also, another question, if you turn it off the light goes on. I assume when you restart the car the light is still on and auto start stop is disabled?

The harness is just a very slightly different shape. I believe the module was modeled for the A4 but of course works for S4/S5. Maybe the A4 has a different female connection.

Correct, when start/stop is disabled, the light is illuminated. The light will stay illuminated even after restarting the car next day. I haven’t touched My start/stop button since I installed the module.

My S4 auto start/stop has never engaged. Probably because I have never driven the car in "D" lol. Pretty interesting though.

Thanks for the info, i asked the seller to pre-cut the harness and ordered one :)

Or just get an APR tune and its all taken care off thank god they did that

Yea, this is just a simple, cost effective solution to anyone looking to have control over auto start/stop. Unfortunately, the $60 spent did not include a tune.

[bigbas101]

I just received the unit but it didn’t come with the keys to pop the panel out. Anyone know what else I could use instead of the keys in the above pictures?

[killahb36]

I have an OBDeleven any way to disable the start stop on my 2020 b9 A4. Thanks all.

Order some they're cheap as chips. Install takes about 30 seconds.

[will13k7]

with the software tweak, you don't need AC on, just the HVAC on. If you have AC off, fan at it's lowest speed, and temp set to 'LO', it's not noticeable and silent.

[Daaavid]

I purchased the module from another seller for half the cost and made a video on how to install. I've had it installed for ~3 weeks now and haven't had any issues; start/stop still works when I go to turn it on but the module turns it off for me every time I start the car. No funny gimmicks; works every time and I still retain start/stop functionality.

For those saying to use the HVAC coding, sure, you can do that, too. I didn't want that method because at times I enjoyed having start/stop working when I was idling in the parking lot with the A/C running. Essentially, the engine would only run if the interior temperature sensor determined that the desired temp was not met and would turn the engine back on to reactivate A/C. Those who live in Texas or hot climates know this is essential and I assume vice-versa for those in colder climates. I've also read that there isn't a way to actually reverse that method once you code it.

The module is as close to an OEM solution as you're going to get.

I just installed one of those dongles in my car as well. Works perfectly and all the buttons do as they are supposed to. Even the auto stop red light turns on. It was a bit tricky getting the panel out with the included tools but other than that, installation was a breeze. Probably a good idea to wrap the dongle's housing with fabric so it won't rattle around in there.

I have this S/S cheat modul from AliExpress. 40$... works...

[Bobby Kinstle]

Mine came from Ebay:

[Tony@EPL]

I have this S/S cheat modul from AliExpress. 40$... works...

It should be defaulted to OFF in the tune... if its not I can take care of it.

[steel234]

I'll check it, but I installed this cheat modul before it was default off, mb it messes up with EPL tune.

I have the kit installed too and it doesn't cause any issues with the tune.

[icon5585]

This is one of the best things I've installed thusfar!

[toxicxk23]

Just installed the one I received from Aliexpress. Holy cow was that an easy install! Slid the keys in until I felt resistance and then a slight push and they clicked into place. Took me a total of maybe 2 minutes. Considering how easy it was to remove the unit, I didn't even bother wrapping the dongle thing. If it starts rattling then I'll just pull it back out and wrap it.

Any issues with this long term?

[RoverJoe]

No, all it does is simulate the button press when you start the car. How those switch panels work, on a LIN network, is it supplies a different resistance for each button, so there is only 1 signal wire going back to the body control computer, rather than 1 for every switch on the panel. So the aftermarket module is simply putting out the right resistance value the first time it sees power, so as far as the car is concerned, you just pressed the button, nothing more. I put one on my car off Amazon, best $30 I've spent on a mod ever. The auto S/S is so harsh on the V6.

Or get a tune and that will take care of it as well, haha.

Our tunes have the Start/Stop default to off.

Our tunes have the Start/Stop default to off.

ah ok. by the way im doing this for an A4 B9. Would you know if this is the same for the A4 Integrated Engineering tune?

[Chris@EPL]

Not sure on A4 tunes.

That explains why it kept turning it on with the EPL tune. Bought this and had to take it out once I flashed because EPL turns it off by default. Essentially I created one of those useless boxes where you flip the switch then the arm comes out and flips the switch.

Yes that's correct. All it does is push the button It does not check the state that it's currently in. If the tune turns it off then the dongle will turn it back on. The dongle doesn't even control the LED above the button that indicates if the system is on or not. That's actually still driven by the computer.
