Disabling Stop-Start 2021 Ateca

[Mr Pig]

My daughter has a 2021 Ateca FR and I'd like to disable the stop-start. I've done this on three Leons using OBDII. Will this work on the Ateca or have they locked you out?

Thank you.

no, it doesn't work anymore. you need a module from AliExpress or a good engine tuner. it may be possible to set the deactivation of the start-stop function to active via control unit 08 adjustment

Not plugging anything from Ali Express into my car!

Turning down the battery requirements in the control unit is how I disabled stop-start on my wife's 2017 Leon. The app does not work. So the same adjustment should work on the Ateca?

I suppose there is only one way to find out!

Give it a bash and let us know!

I know it works on the pre facelift models not so sure after that

It's a facelift car. If it works I'll post the results.

I have used the voltage method on many cars from MY 2013 to 2019, Passat, Golf, Fabia, Leon....... so far so good. A 2020 Golf 1.5 tsi didn't respond at all regarding change of voltage limit.

In your case - The 2021 Ateca is to new!

19 CAN Gateway 10 Adaptation
Start_stop_voltage_limit 7,6 to 7.8 standard value changed to 12

 

[Mr Pig]

1	Module 19. Diagnosis in for data bus code 20103
2	Adaptation
3	Select limit initial V Stop/start
4	Change value to 12v (Default value: 7.6v)

It's how I do it on my pre facelift launch Ateca with Obdeleven Pro. Vag were slamming the door shut with the Formentor / Leon 4 MQB Evo platform where such a coding solution doesn't exist. That's where the confusion is in the replies between the old and new platforms. Ateca is still "old" platform.

I got my coding on the pinned thread

with 3Q Gateway Index AC it doesn't even work on my Leon BJ17

Yep all the ones marked up as MQB Evo where the stop / start has been knocked on the head using the voltage method

Volkswagen Group MQB platform - Wikipedia

MQB Evo (2019)​

• Audi A3 Mk4 (2020–present)[51]
• Audi Q6 (2022–present)
• Cupra Formentor (2021–present)[52]
• Cupra Terramar (2024–present)
• SEAT León Mk4 (2020–present)[53]
• Škoda Superb Mk4 (2023–present)
• Škoda Octavia Mk4 (2020–present)[54]
• Škoda Kodiaq Mk2 (2023–present)
• Volkswagen Caddy Mk4 (2020–present)[55]
  • Ford Tourneo Connect Mk3 (2022–present)[56]
• Volkswagen Golf Mk8 (2019–present)[57]
• Volkswagen Lamando L (2022–present)[58]
• Volkswagen Multivan (T7) (2022–present)
• Volkswagen Passat/Magotan (B9) (2023–present)[59]

• Volkswagen Tavendor (2022–present)[61]
• Volkswagen Tiguan Mk3 (2023–present)[62]
• Volkswagen Tayron Mk2 (2024–present)

So the coding of those cars follows along similar lines. But this is the Ateca thread but those are the ones where things changed. Where on the Formentor and Leon 4 side you eyeball the other models for ideas if it not been published yet and the system in question is the same. There is a related MQB Evo where it's also knocked on the head.

Then you have SFD2 in 2024. SFD1 from 2019 the companies bought the rights to use it. Flag waving thing. So Vag picked up a fee on those MQB Evo models.

SFD 2 unlocked for 2024 models | OBDeleven

Has anyone been successful in modding a 2024 year model? I learned from an expert coder that SFD 2 has not been unlocked yet. Therefore we are not able to code some of the things in OBDeleven in our

forum.obdeleven.com

The real expert is @East Yorkshire Retrofits ... see what they have to say on SFD2 for reference.

This has nothing to do with mqb EVO. mqb Classic was also affected.

Vag slammed the door shut on everything other than the voltage method prior to 2019 platforms then extended it into the new platforms from 2019 knocking the voltage method on the head, that one you quote isn't the voltage method I don't think which should have been deleted in anycase. Only the voltage method went forwards until the MQB Evo platform and an associate arrived. Old platforms are fine including the Ateca.

My next car will be an EV so I'm not bothered .

Hi,
i did it on my car (seat atéca 2018)
it has worked perfectly for over 1 year!
assembly in less than 15 minutes!
the cable is plugged behind the original on/off start/stop button
and it reverses the function (more logical)
as soon as you turn on the ignition, the start/stop service is off and the button is illuminated, if you want to put it back in action, press the button and the start/stop button light goes off and the system is in service!

The voltage method works on the preface lifted Ateca but then ofcourse you got to have a coding device or the wired method which you mention. That's a cost benefit analysis of the two and if you are going to do more coding. The wired method is the Australian DV52s method, think people started selling the kits from it. Seem to recall a circuit diagram.

Golf mk7: Auto Start/Stop disable switch - who wants to help? [Archive] - VWWatercooled Australia

A while ago now, I hosted a short discussion of whether it would be possible to automatically disable the S/S facility on a mk7 when the ignition is turned-on. As those that have this annoying facility will already know, the car doesn't remember the position of the S/S button after the ignition...
