I had the same problems.. add a5 back to the gateway list then remove the negative clamp on the battery.

Any idea if this is due to something coded incorrectly or from not having the AI button? It is not related to the AI function. In order to active the maneuvering assist, you must have 12 radar sensors + 360. |

Ahh thanks for clarifying, that will be why it doesn’t work on mine then, I have no extra sensors around the wheel arches and no 360 cameras. |

In order to active the maneuvering assist, you must have 12 radar sensors + 360. I’ve got the radar sensors (12 I think, will have to count. EDIT: 12 confirmed) and 360 cameras, but yet not able to activate MA WITH automatic breaking. It activates when ACC stalk is pushed away and steers but when it should brake I just get the “MA not available, contact workshop” message. I cross checked my coding for the brakes and all other coding as well. I even rolled it back and cleared all faults and did it again. Anyone has an idea, or managed to get around it? I’ve got a 2019 Q8, with full assistance systems (as it seems?) except parking and trailer assist. Edit: my stock assistance systems - pre sense front, rear and side, crossing assistance, ACC, ALA, cross traffic alert etc. it even says (direct translation from Swedish) parking assistance front and rear with active side safety assistance, whatever that is in English. |

I had the same problems.. add a5 back to the gateway list then remove the negative clamp on the battery. This also works in the A7 4K/C8. Remove the battery negative cable (thick black cable) for 5 minutes, and re-connect. Then clear faults. On the A7, it's really difficult to get to the negative post of the battery, so I just followed the battery cable where it meets the chassis (only about 10 cm away), and undid it there - make sure you've got at least 1 door open. Also, you might find there is a monitoring/sensor cable on the battery negative post - once you've removed the main cable, I also removed this (it's a 2 wire connector), the re-plugged this back in before re-connecting the main cable on the chassis. (I think this is the battery condition/charge sensor). Once everything was re-connected, there were lots of faults from lots of different modules, I went in one by one and cleared them. The only one that needed some work was the front driver's door module, as it lost the basic settings for the window. Just fully lower and raise the window a couple of times, and it goes away. |

Good news regarding the remaining coding for Maneuvering assist So far I have used the coding from this post, which has been working fine, just without the brake function. (Thanks to Karlis for the initial finding) Seems like I found the missing bytes in the Address 03: ABS Brakes module So far I have teste the Brake function with a cardboard box for the front and rear brake function, Both working. Below is my complete coding including the 03 module. STG 09 > Adaptation: MAS12843-Maneuvering brake function,activated ,1 STG 44 > coding > Byte 02 > Bit 1 auf "Maneuvering assistant,0=not active / 1=active" STG A5 > Coding > Byte 44 > Bit 5 auf "MA_sterring,active" STG A5 > Coding > Byte 44 > Bit 6 auf "MA_breaking,active" STG A5 > Coding > Byte 44 > Bit 7 auf "MA_maneuver_assist,installed" STG 19 > Parking assist > coded STG 03 > Coding > Byte 10 - Bit 0 - Activate STG 03 > Coding > Byte 24 - Bit 7 - Activate NOTE! Address 03: ABS Brakes (J104) has to be coded as a pair. Meaning you have to code/set byet10 & Byte24 at the same time, Or the coding will be rejected. Since they are a mirror of each. Module 03 - Before coding Byte 10: 01001000 Byte 24: 00010010 Module 03 - After coding Byte 10: 01001001 Byte 24: 10010010 I did the coding with VCDS but should be no problem with OBD11… Thank you I saw this and followed. What am i missing? A6 c8 model |

I see, you are not able to activate MA. Have you tried pushing your ACC stalk away (to off). Not sure it is necessary on all markets but try it. |

But it turns off and on again and again Is it steering but not breaking? Tested with a box in front? Did your coding get accepted, or was some codes not working? And did you code the bytes for the brakes (control unit 03) simultaneously? You can try removing the negative clamp from battery to force a reset of the modules and see if it works. But You probably need to cross check your coding again. |

Hi,
As I said before, the MA was not properly working on my A6 C8, even if the coding was ok.
So I changed back all the settings (one by one, not with the backup tool), and then unplugged the battery clamp ( very easy on A6 avant), and no more error messages on Dashboard,
I still have an error on module 19-Gateway : U112400 - Data bus - Additional installations detected, but without viseable impact out off Obdeleven.

That one, plus the *much* thicker black wire. It connects to the chassis just forward of the battery. You'll likely find it easier to disconnect it at the chassis rather than the battery. Leave it off for 5 mins. Seems to reset any lingering faults. This won't fix incomplete or bad coding though. You still haven't really answered what you did in the first place. The coding changes listed earlier in the thread worked flawlessly for me, so posting what you did is essential for troubleshooting help. Also, what car and option packages do you have? |

I have q8 2018. Everything works except braking. I am coding obdeleven latest version. Any ideas? Maybe there were too many encodings before, how to reset the settings to the stock (I made a backup earlier)

Well, braking does not work here.
You vcan see the MA starts steering at the garage, but then comes at the wall and goes in alarm ("see workshop" it says). It recognises an obstacle, so i think it wants to brake.
But because it doesn't brake, it goes in alarm i guess ?
Also the steering is not that smart, it goes straight at the wall xD |

Looks like MA breaking function depend on firmware or hardware version. 2 ECUs ESP(03) and Drv Assist zFas (A5) should be envolved in process.
To find dependency, after testing MA function please also write this ECUs HW and SW versions.
We can make standard report to compare components of cars.
Car model:
Breaking: y/n
ESP(03)
HW:
SW:
zFas(A5)

SW:
Errors in ECUs:

Russian guys madе Intelligenter Park assistent for Q8. Steering and braking as well as switching the front and rear gears are fully automatic.
Button installed.

So far I have teste the Brake function with a cardboard box for the front and rear brake function, Both working. Looks like MA functions depend on some modules hardware or software versions. Could you please share more info about your car, like VCDS auto scan?

Well, since i didn’t get the braking to work, and the MA braking function starts freaking out everytime i’m parking...
I reversed the whole coding yesterdag.
Now got some errors that won’t clear.
01- Engine:
U107A00 - Camera control module
No communication
17- Dashboard:
U101400 - Control module incorrectly coded
19- Gateway:
U112400 - Databus
Additional installations detected
A5- Driver assistance:
U112300- Databus error value received
Inside the car everything seems to work, except i’m getting a message “emergency assist not available”
Anyone some ideas ?
EDIT:
Just disconnected the battery for 10 seconds, started everything back up and cleared all faults.
The emergency assist fault in the car is gone so thats’s nice.
01- Engine: is okay now
17- Dashboard: keeps the same fault
19- Gateway: keeps the same fault
A5- Driver assistance: no faults anymore, but keeps “yellow”

For 17 Dashboard, change "intelligent park assist" from "No" to "Yes" will solve your issue, all green.

17 - Original it was “no”
19 - “coded” or “not coded” both keeps the fault

I've an A8 and at the end (similar fault codes) I had to go to the dealer. They had to remove the luggage compartment trimming for to reach the battery. Then they made some reset and had to adjust something with the 48V Battery. Now every thing is fine :-)

Hello. Anyone found the solution with breaking? Everything seems fine, no errors, but breaking doesn't work.

Braking function is working only on zfas with software version 4KE907107AR, modules with 4KE907107AC can be flashed but it is tricky. We already done full retrofit of MA on Q8, A8 and A7 by flashing units to AR software and MA working fine after that. All codings mentioned here are correct.
