Hi. I'm considering buying OBD11 to make some changes on my car, mainly the ability of wireless Apple CarPlay. My infotainment system has a hardware H56, software 1940, ABT hardware H37 and ABT software 3074 (the car is from 2021).
I want to aske if it is possible to activate this option on my car (just to have my expectations set when I do buy the OBD11).
Many thanks in advance.

Anyone know the correct coding for PACC variable offset speed?
Now when traffic sign reads 60, it sets 60.
I want to adjust 60 to 66, next time 60 sign is read, it should set speed to 66.

There are very different ways found for different vag cars, maybe someone knows working way

You first have to tell the ACC that it should learn to have an offset. This can be byte 21, bit 4. Then you have to tell the system that it can do this, too. Set byte 08, bits 0 and 1 to active. Then, in the ACC assistant menu, set the tolerance to low. All information is provided without guarantee.

Hi Everyone,

I have been having a play with OBDeleven with my car (FR First Edition) and have managed to code some things and thought Id share what I have found and create a thread where people can share there findings for us all.

I have managed to code:
Cupra Display
Lane Assist Point Of Intervention (Have yet to test, but should keep the car more central rather then let it almost drift out of lane before kicking in)
Lane Assist Set To Last Setting
Lane Assist Warnings Turned Off


I know a lot of people find lane assist is already to sensitive (its already set to lowest from factory), so I might have found a solution to this too. So you can turn it off and it will remember this setting each time the car is turned on etc, so now you can make it sensitive for the motorway and only turn it on when you want it.


Cupra Display:
Module 17 (Dashboard) -> Long Coding -> View Activation -> Set All 16 Views to active -> Write To Car

View attachment 21580

Lane Assist Point Of Intervention:
Module A5 (Driver Assistance) -> Long Coding -> Point Of Intervention -> Set To Early -> Write To Car

Lane Assist Warnings:
Module A5 (Driver Assistance) -> Long Coding -> Lane Assist Off Text -> Set To Disabled -> Write To Car

View attachment 21581

Lane Assist Settings:
Module A5 (Driver Assistance) -> Long Coding -> Configuration For Lane Departure Warning K15 -> Set To Last Setting -> Write To Car


Let me know what you guys find :D
I really want to add the "Cupra" view to our Leon FR. But, I cannot find the option "view Activation" after choosing "long adaption".

Tips anyone? Am I overlooking it?

Oh and another (dumb) question, we have cc, to active to adaptive. Do I need to have something extra installed like a module or something?

Thanks will try tomorrow.

Yes, we have the normal cc now. Is it possible to code it to acc? Or do we need to have additional details hardware / module?

FeC / Swap the same. Ah Leon 4 you are locked out from changing them unless a dealer or authorised Vag specialist. Gone are the days so it seems of the mib collective of hobbyists changing them. You can inspect them on a mib3 by holding on to the menu button till a screen pops up. The normal way then a Google will tell you what they stand for.

I always say it's like buying an HD TV but only showing SD. It's built fully capable but they want you to pay a license fee to get the full benefits of the hardware. Now it would be a Dolby Vision / HDR10 TV that only showed you 720p unless you cough up to unlock it 😉.

They are marketing levels that you pay to enter to get the full capability of the hardware / different functionality. Like the much sort after sports screens of Leon 3. People payed good money so they could see Cupra type of screens. You could also unlock offroad although you'd be more unlikely to go offroad in a Leon3. Mib2 enthusiasts unlocked them all for free.

Sorry for another question.

Thougt I saw someone mentioning it is possible to add 10km 30km 50km and so on to the speedometer? Sadly I can't find the coding for it, someone has it for me?


Found it!

Much much appreciated!
