michael4819 Hello. I really doubt but here is silly chance still. I found out while coding that 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. Probably it could be an indicator for you instead of clearing faults for half an hour.

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 ) The 48V starter/alternator has a voltage converter so that the alternator can charge the 12V battery. The 48V battery does not feed the 12V system if you disconnect the 12V battery. When the car is off, disconnecting the 12V negative cable (and monitoring harness) is all that's needed to disconnect power to the various ECUs in the car. Other users who have used this method said that leaving the battery off for 5 mins was all that was necessary to clear the "sticky" faults.

Thank for this information this would be great. Here comes why I am not sure if this process would work on the A8. In the AUDI documentation is clearly said that the 48V is supporting the 12V system. And it's impossible to get the 12V voltage free without disabling the 48V->12V converter. There is another thing to know on the A8 battery system - you habe to unplug the PLUS-Cable, because desing-related it's not possible to unplug the MINUS-Cable.
Due to the documentation I think just disconntecting the 12V PLUS-Cable wouldn't be enough. Also I would feel much better if the 48V subsystem is disabled - befor working on the 12V system...

The A6 and A8 (and others) are based on the MLBEvo platform, so I suspect the MHEV setup is the same. (What year is yours?) If you're still gun-shy about working on it, I'm sure a call to your local service center can get you a definitive answer.
I don't know about the battery connection setup in the A8, but if it's anything like the A7, the negative battery terminal isn't easily accessible, so you follow the large black wire from the battery to where it connects to the chassis and disconnect it there.
I just got my P>> button, but I'm not even able to get to the point where I can choose a parking space. I appreciate your efforts to get it working!

I just realized yesterday that my assistants physical button (to the right from installed >>P) doesn’t work. I’ve tried to clear all the faults but nothing changed. However I believe it was working after I installed new buttons block. Does anyone have the same issue?

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 😔 How did you manage to get the soft button working? I have coded mine following the advice given here and its greyed out like others have it?? I have ordered the new P>> button so will install that when it arrives.

Hi guys,
lots of respect to the volume of you work. Is there any update on this?
Is it working? Provided, the >> P button is installed and coding was made according to the latest post here. There is transmission malfunction... Guess, there must made some adaption to the 02.
Can anybody provide the coding of 02 with IPA installed? Mine is "000001". I found some modules coded to "100000". Might that be the missing coding??

Finally pulled the trigger on the button last week and installed today. Was definitely not the easiest nor most pleasant experience. Regardless got it installed, cleared all error codes - drove down to a parking lot, and it worked! No need to code any gearshift, etc - shifted forward reverse and park without issue. Unsure of the exact scenarios it works, but was difficult to find a “spot” It would recognize. It seems to require a well-lit lot with other cars around. Unsure if there is any additional settings or tuning to help it discover spots.

Congratulations, matt! But couldn't you try to answer the question I raised a while ago? It could really help a lot of guys here with greyed out soft parking button.
Aug 26, 2020 at 12:33pm " 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? "

The coding used I had posted back on page 1. I do intend to run through my modules again to ensure I haven’t missed anything though.

Congrats Matt
It would be much appreciated, if you could find the time to share a copy of your long coding for module 09 – 13 -17 – 44 – A5
Think we are quite a few, that would like to see a white steering wheel on the screen instead of the gray one :-)

Hi Matt,
congrats to getting it run!! Could you please provide your revused codings?

I can confirm that the codings I have posted back on page 1 were the only codings needed to activate this on my Q8. I was able to initiate the parking search before installing the button but not actually park. Once installing the button all is well.

Matt, this is not possible. More than 5 people (A6, A7, SQ8) of mine did not get IPA run according to your codings. Kindly asking again for a full dump of your modules.

Well I got one quite strange thing yesterday. When I stopped at the traffic light in the middle of the day and checked the lower display to adjust the climate, I realised that soft parking button is displayed white. I pushed it right that moment and for a second or two I saw parking spot search screen appeared, which was posted here previously. After few seconds the screen got back with the message that the system is not available now and parking button turned grey. Needless to say I didn't code nothing during last month.

Exactly this happened also to me on Saturday. For 3-4 seconds softbutton turned into white and then turned to grey again.
I checked some other codings before. Now I have no faults in the modules anymore, though IPA still returns "not available" when I push the softbutton.
Some guys have reported that, according to VCP data, there are paramter values which need to be applied on more than 8 modules. If this is true, IPA cannot enables just by coding.
I have ordered kufatec kit in Germany now as I do not suppose that anybody is able to share the relevant information completely.

It's really bad thing if we have to parametrise the modules. However I believe not only matt but few more guys were able to activate search with soft button before installation of the physical button. Now I'm really lost especially with the case happened to both of us lately.

I have used some other coding than Matt which subsequently cleared all of the faults. For this I compared hexcoding of a friend who had already the pluged the switch and coded IPA with the kufatec dongle. Again: Matt's coding resulted in faults in 44 and A5. My friend advised me to reverse all coding and re-code again. I am usure if I want to spend more time on this or just wait for the kufatec dongle.

I checked kufatec solution and it's quite expensive and they don't ship to Russia. So if you bought one didn't you decide to sell it further after using to split the cost. Maybe I'd like to buy it from you. However after all the coding applied there are 3-5 errors in the modules mostly regarding busses. And even if I ran full backup as my first action after buying OBD11 I didn't check it right away but now I couldn't find any backup in the system. So I couldn't restore initial parameters and not sure if dongle will help me. BTW what are the chances for OBD11 to perform the app for the IPA? I think there should be demand even for not 10 nor 100 but 1000 credits.

I asked Kufatec about just buying the dongle since I already bought the button and they said they don't yet have a solution for the 2019 A6, so perhaps those of us with that "vintage" are stuck. I certainly hope we can continue experimenting and find a way forward, but for now it seems like we're out of luck.

Post by tempos84 on Nov 9, 2020 18:44:46 GMT
So they only have it for the 2020 A6? I don't really think there should be any critical difference.

Post by davedavez on Nov 10, 2020 0:05:17 GMT
I agree. I can only tell you what they told me, which is that the 2019 has no current solution. Perhaps there is a newer HW version of the zFAS that supports the park assist?

Post by mossox on Nov 11, 2020 8:47:34 GMT
It won't help selling the dongle as it is applicable on only one VIN. The have some clever code to enable block bits on the flash write commands.

I think there should be demand even for not 10 nor 100 but 1000 credits. Kufatec has done considerable work in order to offer ready solution for enabling IPA. Nevertheless there is some cleaning job to do after applying their variant of codings/adaptations by modifying/disabling some of them (after using the car more then 2 weeks and studying errors it generates).

Post by mossox on Nov 12, 2020 9:47:39 GMT
Yes, you should definitely clear all faults after 1-2 days. Afterwards no faults relating to IPA coding should occur anymore.
Although of course there could be new faults esepcially in the A5 sensors relating to bad sight now in November...

Post by yousha on Nov 12, 2020 11:56:46 GMT
I have expressed myself not correctly. What I meant is that Kufatec’s product did some “overcoding” and after analyzing modifications that were done in related control units codings/adaptations you need to proceed with some adjustments, otherwise new faults reappear every time.
|
|

Post by mossox on Nov 12, 2020 14:14:06 GMT
That's possible. But before plugging the kufatec dongle you should have reversed your prior experimental IPA codings. I think it's more possible that this is the reason of any persistent faults now.

Post by yousha on Nov 12, 2020 15:50:04 GMT
Sincerely, I was not experimenting with IPA codings (considered that it is too complex and risky). There were another options to get required codings&adaptations related to IPA. (PM if you would need add.support and info).
