Good job rockl! Are you sure that additional wiring is not necessary when changing to >>P button? Not sure yet. It appears that the >>P button is operating normally as I get this message when I press it:  The problem is I can't activate the parking space search because the soft button is grayed out:  So I need to figure out why that is happening first. I believe others here are able to activate the parking search, but dont' have the button installed yet... |

In my case it’s the other way around indeed.
Soft button is working properly, but it asks to push the hard button.
It’s in a box at home, but i’m on vacation now 😬😬
But i know the braking doesn’t work on my maneuver assist, so pretty sure it will be the same at the parking assist 😔

Agreed. Breaking is still a missing link. I wish we had a full scan of an A6 with park pilot from the factory...

Been looking at the Audi A6 C8 wiring scheme. Seems like there might be some additional wiring for the “new AI park” button compared to the original button, depending on the factory build equipment. All cars has 3 wirers to the button panel original from the factory, but with the new AI Parking function, an extra wire (Pin 5) to the Zfas (Central driver assistance controller)module is required. My own A6 is factory equipped with area view (PR No.: KA6) as well as park distance control (PR No.: 9X0) And do miss the wire on pin5 to the Zfas module. Might be one of the reasons for the parking function being greyed out, after the button is installed. Have attached the wirer plan with the missing wire on. EX23 is the center console switch  |

But I think that the wire to Zfas (it’s on pin 4 by scheme) is required to run the assistant profile selection. And there are 2 buttons indicated at Ex23. Could you please check if there is variation with >>P button at wiring diagrams? I just received today switch module with >>P button. Will try to check if I could get inside it and check the inside wiring. |

EX23 is the center console switch That may be the case indeed. It would be a fairly easy route for a new wire under the carpet. The most difficult part would be pulling up the footwell carpeting... I found a good source for details on the 2019 J1121/A5 module and Driver Assist functions: procarmanuals.com/vag-ssp-990693-the-2019-audi-a6-introduction/and a slightly earlier source for the 2019 A8 Driver Assist systems including Park Assist here: procarmanuals.com/vag-ssp-668-audi-a8-type-4n-driver-assistance-systems/The give a great overview of each module's function, and bus interconnects. Based on this info, it looks like those without the surround view cameras have 5th gen Ultrasonic sensors need to use the J519 control module (09 - Cent Elect) as the Park assist Master, while those with the surround view cameras have 6th gen Ultrasonic sensors need to configure J1121 'C' (A5 - Driver Assist) as the Parking system plus master. The key indicator seems to be the version of the A5/J1121 module. Versions A, B, or AO don't connect to the Ultrasonic sensors. Version C of the J1121 module accepts the 6th gen Ultrasonic sensors directly.     I have Version C |

Well, the switch module has only 4 male pins at harness. These are 1, 2, 3, and 4. It has multilayered board so pins couldn’t be easily tracked. But for sure all 4 are connected.
So if we only have 3 wires then 1 have to be installed. Could anyone check for pins part numbers and needed module position? If it’s pin 4 then it looks like it should consist of 3 parts between two modules and two coupling points.

For Q8 only 1 interconnection point between buttons and zFas. Connection point on the center of control panel.
Actually LIN bus connected to the button assembly is enough for send and receive any commands.
Pin4 named SIG looks like some logic signal.
Checking pin 4 state on button assembly connected to the car with multimeter and push buttons can put the light on pin function.

hello guys,
do you have the front crossing sensor?
without having it installed, it will not work.
if so, can you share your original coding with me/us please?

But there is some other schemes. is seems like Cars with Parking aid (PDC) , (7X5),(KA0),(KA2) is only equiped with 3 wires. Cars with 7X2 = Park distance control front and rear is only equiped with 3 wires. Cars with KA6 = With front and rear view camera system and two side cameras, is equipped with 4 wires. Reason is properly that the camera and sensors I connected to the Zfas module . |

hello guys, do you have the front crossing sensor? without having it installed, it will not work. if so, can you share your original coding with me/us please? For what reason do you think the front and rear radars is used for AI parking? Quite sure that the ultrasound sensors and the area view cameras is sufficient to handle the AI parking. To my knowledge, radars is used for dynamic objects and is useless within a few meters. The radars is not used in conjunction with paring anywhere. I might be wrong…. AtT kufatech’s webpage they write: only suitable for vehicles with area view (PR No.: KA6) as well as park distance control (PR No.: 9X0). They might be wrong to… Finding coding dump from a car with the option available, will make life easier |

ustolle : on Erwin, when I look at the diagram of the modules on the autonomous car park, the 4 corner sensors are indicated. After actually on the kufatech site he does not talk about it, but they say there is some extra wiring which is not shown on erwin. so i will try my codings again now that i have the SWA working.

Well I also think that radars should be installed to enable parking pilot. Couldn’t remember where I read it first but I talked with those guys who installed it on Q8 (I’ve posted links for video and photo earlier) also mentioned that car should be equipped with blind spot monitoring and cross assistant. Btw, they asking 1 k$ to run parking pilot. Well, I finally got my car and it’s really fully equipped with assistants and options. Based on that it looks like I even should have 4 wires going to switch. So just need free time and tools to install but there should be some problems. Just realized that radars are probably not directly needed for the parking process itself but It could be good to check that the car will not hit someone during that autonomous process.
It was close but missed still. Yesterday I got under console (it wasn't easy walk for the first time for me) and found out that I have 4 wires going to needed switch. I've changed the switch and coded as mat did.
Well soft parking keys popped up in lower and parking displays but they are greyed out and when I'm trying to push it I got the message that "needed system is not available at the moment". When I push the new physical >>P button I got the message "please activate parking assistant to search for appropriate spot". Lately I got dipper in to activate manoeuvre assistant and curb assistant along with some other tries and left out with 3 errors - U112400 "Data bus. Additional installation detected" in 19 and double U112100 "Databus missing message" in 44.
Here is what was initially coded for the parking pilot:
The full coding I have used to this point looks like:
A5 > Long Coding
- Byte 13, Bit 3 (10111000)
- Byte 18 > Bit 0 (01010111)
- Byte 33, Bits 0, 3, 4, 5 (10111011)
- Byte 34, Bits 3, 4 (10011000)
09 > Long Coding
- Byte 8 > Bit 4 (00010111)
- Byte 13 > Bit 6 (11111110)
- Byte 28 > Bit 6 (10011011)
- Byte 39 > Bits 0, 1, 2 (00000111)
44 > Long Coding - Byte 1 > Bits 0, 2, 4 (00010111)
17 > Long Coding - Byte 14 > Bit 4 (01111000)
STG 09 > Adaptation > Show parking space > Activated
STG A5 > Adaptation > Visual display for park assist OPS display > With OPS 360
19 Adaptation Installed specified list -> Park Assistance Not installed Installed
Most of the bytes however were not fitting to mat's initially.
And I found one thing - when I changed in long coding IPA automatic activation selection (I think its A5 module) between manual and automatic, soft parking key blinked into white for half a second.

Thanks for letting me know. At least now I know I'm not alone with this limitation! I believe my car also has 4 wires to the new >> P switch based on a photo I made when I was replacing the cup holder last year. The wiring diagram indicates the white wire carries the signal to the Zfas module, and I can see I have that wire in the photo from last year. So based on this and the fact that we get an error message indicating to first select a parking space leads to to believe that we don't need another wire from the EX23 switch to the Zfas. Now we just need to figure out how to get the parking space search and break functions to work. Sure would be nice to get a full backup from a car with this enabled from the factory. Attachments:

I believe latter cause we know that technically it's possible. We have to think about next steps now ) It looks like previously matt and few more guys were able to got active soft parking key working with the same coding we did. But they didn't install hard key that time. So I wonder will soft key become active if we change the switch module back to F version (without >>P) and don't change anything in code. BTW it looks like my manoeuvre assistant works, at least braking (and that was hard part for some of guys), got that today during parking  . But curb assistant doesn't work, just got wheels strikes out. I believe my car also has 4 wires to the new >> P switch based on a photo I made when I was replacing the cup holder last year. The wiring diagram indicates the white wire carries the signal to the Zfas module, and I can see I have that wire in the photo from last year. Yup I think you have 4 wires cause none white wires there except for the 4th pin (check my photo bellow). And the fact that car could see when you push >>P button.  |

Well I seem to have made a revelation tonight, finally got a variation of Park Pilot enabled, however it can't be used because it instructs me to press and hold the "Audi AI" button in order to complete the park, and I don't seem to have that. Also seem to have figured out Garage Pilot, and Mobile App Parking, also useless without the right mobile app. Potentially a lesser version of "Park Assist" could be enabled that doesn't require the Audi AI button? Thinking there are 3 versions per say of parking assistance, the 360 sensor parking, parallel parking assistance where you shift, and park pilot, which does it all but you need to hold down the button. Somehow I need to figure out how to achieve the second option rather than the latter....  Hey matt! I appreciate the volume of work you did to make parking assistant working on our cars. Could you remember please what coding you did right prior to this post to make soft parking key working as per your previous post it was greyed out? |

For the 21 model you can order 360 and autonomous parking together with the P-button! At least in Sweden. Try to build it at the site, it stands clear.

No luck I think you're on the right track ustolle. After reading the Audi training guides posted above, I see that Audi has at least three different variations of park assist with different levels of assist. The first two variants seem to be Park Distance Control (PDC) and Park Lane Assist (PLA). The one we're trying to activate is Intelligent Parking Assist (IPA) or Park Pilot (PP). The first two variants seem to operate using the 09-Central Electronics to drive the ultrasonic sensors and controlling other modules like 44-Steering Assist, and 13-Distance Reg/ ACC Cruise control. With the introduction of the zFas variant 'C' module, the ultrasonic sensors and all the drivers assist functions moved to the zFas-A5 module. So by enabling all the PDC and PLA options in the 09, 13, and 44 modules, we're creating "missing_message" and "error_message_received" DTC errors. The best approach to solve the puzzle seems to be turning off all the PDC and PLA bits in 09, 13, and 44, and begin by turning on IPA in the A5 module. A5 zFas Module Byte 13, bit 3 Interface Parking Button Byte 18, bit 0 FW_PLA_BCM, installed (Confirmed, this needs to be on else the Parking search icon is grey) Byte 33, bit IPA 0, 4, 5 (bit 3, (IPA_limited_operations, 0 not available) If bit '3' is on, IPA operations are limited. This was causing my P soft button to grey out. Byte 34, bit IPA 3, 4, 5 Byte 44, MA bit 5, 6, Then enable downstream modules to accept control and interact with the zFas and for IPA.44 - Steering Assist Byte 1 Bit 4, Activated variant of park steering assistant, Gen 2 Byte 2, Bit 1 Maneuvering assistant 13- Auto Dist Reg. Byte 3 bit 0-2 Maneuver Assistant Byte 14 bit 4 operation mode 2 (?) 17-Instruments Byte 14, but 4 Intelligent park assistant 03-ABS Breaks Byte 10 - Bit 0 Byte 24 - Bit 7 09-Cent Byte 13, bit 6 Intelligent Park Assist 19-Can Gateway Adaptation: Parking assist > coded The above gets close, but it fails with this error when trying to park with the >> P button: 98341 - Cancellation of Park/Steering Assist B187A 00 [009] - - Confirmed - Tested Since Memory Clear Freeze Frame: Fault Status: 00000001 Fault Priority: 6 Fault Frequency: 1 Reset counter: 52 Mileage: 19340 km Date: 2020.08.29 Time: 12:32:35 Parking assist: discharge reasons (ring memory)-Year: 2000 Parking assist: discharge reasons (ring memory)-Month: 0 Parking assist: discharge reasons (ring memory)-Day: 0 Parking assist: discharge reasons (ring memory)-Hours: 0 Parking assist: discharge reasons (ring memory)-Minutes: 0 Parking assist: discharge reasons (ring memory)-Seconds: 0 Parking assist: discharge reasons (ring memory)-Last reason: Transmission malfunctionSo still some work left to determine which module needs to shift the transmission. I'm assuming it's module 01-Engine or 02-Transmission, but the VCDS doesn't have any definitions for those bits, so need to research. Note that this error also latches in ring memory, so the only way to clear it is to disconnect power from the car. On the C8 A6 it's simple. Just remove the black cable connecting the battery to the chassis for 15 seconds... Parking assist: discharge reasons (ring memory)-Last reason: Transmission malfunction The P button on the MMI will remain grayed out until you do the reset. I also noticed the P button will grey-out when the hood or driver's door is open! |

Might be that coding of the Transmisssion(02) is the only coding missing, according to the error.
Sems like the coding of the Transmission is very limited only 3 bytes available.
00 & 01 dont offer much opportunity for coding.
in 02 there is the option for chosing in a menu for "Variant 1", "Variant 2", "Variant 3" & "Variant 4"
Might be one of the above that can solve the problem.
Mine is "Variant1"
If some of the other variants can be coded without error, it mights be the one

Hello together, I am new to this Forum. I try to enable the IPA on an AUDI A8 D5. After Coding some of the ECUs ( mostly A5 and 17 ) I was able to start the parking search space. But due to missing AUDI AI Button it wasn't possible to go any further. Yesterday I was able to install the AI Button. It was really tricky and took some time. But the Button is installed. My Car has the 4 Pin Connector and I got the Button with the AUDI AI Printed on ( G - Version ). After installing the Button I was able to Start the Process like befor - but the Button had no effect so I decided to code the devices like mentioned in this thread. The Button is now "clickable" but the (P)- Button, to search for parking spaces, is now greyed out. I think that like robl sayed on of the pla codings is "too much". My problem is after every fault I have to wait around 30 Minutes befor I can do the next test, because the Trouble Code is not deleteable. Robl was writing that this is a ring memory fault - which is persistent, in some cases until the 12V system is disconnected. At this point my problem beginns. My car is a MHEV. So my 12V system is just a subnet from the 48V system. To disconnect the 12V system I have to disable the 48V->12V bridge. So here two questions: - does anyone know how to disable the 48V->12V bridge The documentation says that the 48V could be set voltage-free but I don't know where to find this feature - Where do I get the details robl showed in his last post. ( Transmission malfunction ) I am using VCP at this point - but if needed I would also buy the OBDeleven Tool. Hope we get this feature working together :-) Greeting and thanks Michael Here some pictures from the installation, maybe this is usefull for someone...   |

( Transmission malfunction ) Nice post, Michael. Unfortunately I don't know how to answer your questions. As I can understand you didn't mention the moment when you lost the ability to push soft "P" button, right? I mean we don't know for sure what bit kills it so far. As far as I remember everyone who installed the AI or >>P button got soft "P" button greyed out. Don't you think it could be activated again if we disconnect our AI or >>P button without any coding? |

Hi tempos84,
After installing the button the (P) - Softbutton was still working. I was able to start the park space search. But when I pressed the AI-Button nothing happend. So I coded different Systems ( 44/a5/74/17/19/09 ) after that. The AI Button come to life but the (P) was greyed out.
I will revert coding by coding these days to get the old (P) not greyed out behavior back. The Problem is that I always have to wait about 30 Minutes until the memory ring error is cleared ( after that the (P) Button is for a short time after start ( 1 Minute ) clickable ).
So one of the most important questions is at this time. How to disable the 48V System to get the 12V System voltage free.

. But curb assistant doesn't work, just got wheels strikes out.
