Hello and wish you all a great day!
Firstly, big thanks to
@VLud &
@bagou91 for making this amazing tool, u`re the goats!
Here to share my achievements, the car is a 508 II SW 2020, EAT8, Diesel, Night Vision, Wave 4.
1. Big thanks to
@Albatros24 for helping me with the activation of the
park assist, since he already posted his progress on this thread, I`ll briefly follow up his steps with my modifications:
Code:
DAE_BVH2: Modify Zone A0: Replace DD by CC
========

21A0 -> 61 A0 05C0DD0002000000

34A00000000605CCFD000000F8A7
21A0 -> 61 A0 05C0CC0002000001
82
This is what I was more afraid of, but, conveniently enough, his 2020 C5 Aircross has the same power steering ECU as mine, coding was identical, not even needed to change the checksum.
Code:
BSI: Modify Zone 2300: Replace 13 by 33

Straight forward enough.
Code:
AAS_UDS: Modify Zone 2101: Replace A5 by BD

Here, apparently, there are some differences regarding zone 2101 for me, hence, upon reading, hex values were completely different, therefore couldn`t write to it without getting 7F2E13, invalid zone data error so I decided to leave it alone.
Also, I had to change the unlock key to B6F0:03:03 since my car has the UDS_G6 version.
Code:
NAC: Modify Zone 210C: Replace 0010 by C010

Simple enough, although this can also be done much easier through the PSA diag app.
After all the coding is done, for me, at first, I couldn`t access the parking assist menu in the NAC, although the menu was present. I eventually turned off the car for a minute and allowed all ECUs to restart and then it worked, maybe someone might want to know this if they try it before they jump to other conclusions and waste an hour on useless troubleshooting like me

.
Before I go to the next point, The parking assistance works as it should in terms of space measurements, auto power steering, but, since I have an EAT8, it asks me to put in in neutral and release the brake for the maneuver to start , but when I take my foot off the brake, nothing happens, but if I put it myself in Drive or Reverse, it works.
As far as I can tell, correct me if I`m mistaken, it seems that something is missing regarding either the ESP for the brake pedal, or something related to the gearbox. Now, I remember that this subject was already touched sometime, pages ago on the forum, but I don`t remember if a solution was found by someone, if there is and I missed it, I would kindly appreciate the person that could help
me out on this one or a simple reminder if the problem was already addressed before, thank you in advance!.
2. Big thanks and shoutout to
@ezeyhomero for helping me activate the "Driver Welcome" function
Thanks to him and the user that he says provided this zone, I managed to telecode this zone.
Needless to say that for this function to work, you need electric seats with memory function, which I have
234C is a BSI zone and the telecoding is very easy, all I did is write the
00 with
01 and that was it, the code looks something like this:
Code:
>752:652
1003
22234C
62234C00
:B4E0:03:03
2E234C01
1001
Also, while this is all I did, the "Driver Welcome" function appeared in the vehicle settings under the Parking/Vehicle access tab, which allows for the function to be turned no/off. You might need to check with the PSA diag. app. if it`s shown as a visible tab, if not, just choose it in either of the available tabs and you should be able to see it.
In conclusion, I did test this zone on my car that has electric memory seats and it works 100%, as far as I can tell,
@VLud, in my opinion, this could be safely implemented into the app and/or
github on the all zones thread, because at the moment is not present. (old me

).
I also managed to activate several other functions like: activation of all ambiance themes, display of the iCockpit Amplify function (wich my car had it in the beginning, but oddly enough, at some point, it disappeared...), activation of the trip computer in NAC, ECO coach. Although these subjects were covered on this forum before, but I`m glad to help to the best of my abilities if someone requires it from me

.
I will link my log file alongside my original backup calibration for my car because if it helps this concept even a little bit, I`m more than happy to contribute, because this is a gem for DIY passionates that just wanna` make as many things as possible to work!
For the end, I want to address a few questions of my own and I will be more than grateful to whom will be able to help me
- The previous presented matter of the brake pedal/gearbox not working properly with park assist.
- When I activate iCockpit Amplify, for some reason, if I select either Boost or Relax, engine mode won`t change to sport or eco/comfort, is this a bug, has anyone encountered it and is there a solution?, because in the meantime , I disabled the option to change engine modes in iCockpit Amplify.
Thanks in advance and cheers!
