2019 Audi A8

david33316 if you already have the device/app why don't you just try it

it works just fine on my 2019 A8. Turned on wireless carplay and a few other tweeks.

I test it on Audi A8 2019 and it did read all the information and clean Faults , but i couldn't change anything , neither the Apps nor coding or adaptation , also no Service Access Codes worked , even the once that are presets from the App. I also tried to clean the cache and data from the OBDeleven APP from my Samsung s10+ , but nothing helped . Before 1 week i also used the OBD eleven on 2017 a7 and it worked without problems , also i have already used it on Tiguans , Passats and Golfs and it worked for everything .
Anyway back to the Audi A8 D5 , everytime i try to unlock Apps i get "Fail" error on the bottom of the screen and also it takes my credits points away... Everytime i try to Long code or adaptation or to enter Service Access Code i get "Something went wrong" error . If anyone of you have any ideas please share . Or should i go straight to the support ?

I wrote yesterday with the support, they told me to Turn ON the Handbreak and open the Hood. It's a new Security system for the VAG Group. I will test it out later when i can and see if that works.

Yeah, I am with Android, but I don't remember any notification or pop up to show that I need to open the bonnet. But it doesn't matter now, today I test it and everything worked as it should. And Yes the Handbreak should be ON with the hood opened to work properly. Now I need to figure out how to lower the suspension. From what I have found in the other forums, there is some other guides, but they all show that you need to enter Control Module 34, but on this car the Module is 74 for the Suspension. I already found the right place to thinker, but neither Security Access Code 31564 nor 20103 works there. I haven't test to change the values of how high the Suspension needs to sit or to do calibration, but I will do it tomorrow or in 2 days, because the car needs to go to Audi for some service. I searched everywhere, but there is no exact info for the same car with the same module.

Well at the moment this Audi needs specific kit or software that can be bought to lower the car. So no cheap option . From what i got as information until 2017-2018 can be modified with OBDeleven and for the newest models you will need to pay. Probably later they will start to release stuff publicly, but not at the moment.

Works fine on my A8 D5, I have changed quite a few things, do read the instructions, hood up for most of the programmimg and don't worry about the faults, most are communication errors, the D5 is Sillion Valley with 4 wheels. Just clear the codes.
