Get in touch with Blackbox Solutions (if you didn't do that already) and figure out :
1. if a cruise control should work with ACC steering wheel
2. if 1 is possitive then most probably there is something wrong with steering wheel buttons or PCB Boards.
Hello, good afternoon PPETKOV, I have already contacted Blackbox solutions and they are holding me back. They tell me that it cannot be a fault of the PLB and that I should send them to them at my cost so that they can check them. But I am from Valencia, Spain and I have to pay customs and so on. So I am still looking for a way to solve it because sending them back costs me a lot. .
Hello, good afternoon PPETKOV, this is the other steering wheel that a colleague left me to try and I installed the PLB and it does the same thing as the one with ACC. What is the SET+ button, it does nothing and in diagnosis it shows me a fault with cruiser control not powered.

I’ve tried searching but can’t find an answer to my question. Is it possible to retrofit ACC to a vehicle with manual gearbox? 2010 2.7 D4 if it makes a difference. I’m assuming it’s an auto only option, but can’t actually see it confirmed anywhere.
Thanks.

@Dondiddy, many thanks for your 2020 post and link to the very useful article.
For anyone else looking for it, discovery-parts.de seems to have been rebranded as expedition-parts.de
It can also / still be found under their "Landrover things" page (home page, top menu) with the title:

Hi guys, this is my first reply here in this nice forum, which helped me a lot, since I own my RRS 2008.
I actually have all the needed parts together to retrofit ACC by my own 💪🏻
It would save me a lot of time, if @Ollie795 can share his 3D-print drawings with me ❤️
Thanks in advance.
Will reply here, if everything is installed.

Well I can confirm it works! and with an added bonus no need to cut the bumper on a D3
Heres what I did....
Ordered the following parts:
Radar sensor: Delphi 4R83-9G768-AA for a 06-09 age car
ACC ECU: NNW501922 again 06-09 age car
Centre console switch: YUL500320WUX
and the steering wheel switch: XPD500850
All the wiring is 0.5mm I decided to follow land rovers colour scheme to keep it easy to follow
I made a wiring diagram although there are some on here further back in the thread
I decided to mount the ECU in the auxiliary battery tray using a 3D printed bracket:
I tapped into the high speed can bus on the ABS loom, bit of a fiddle but it was the shortest run
Then ran the cable for the forward alert facia switch, there is a grommet to the right of the brake servo, I made a hole through the firewall insulation from the engine bay then pulled the wire through with a bit of copper wire
Then I replaced the facia panel with the one with the forward already switch, had to swap the face place from another discovery that had the extra button space
Next was fitting the steering wheel switch pack, easy job if you have the airbag removal tool, I managed to make one my self
Then it was on to the loom, I wanted to make it removable incase any work was required and it was in the way so the fuses can easily be removed in the engine fuse box, and the ecu end of the loom has a separate 9 pin plug that detaches from the ecu/hs can bus/FA switch
It’s just one big loop around the front of the engine bay
Then the final piece to fit was the radar, having seen where it was originally fitted on the Range Rover sport I wasn’t overly keen on cutting the bumper, but then I found this picture:
On the jaguar it’s mounted behind the bumper which got me thinking that maybe it can sit behind the grill…
So I made another 3D bracket for the radar and utilised the 2 holes in the crash bar:
Took a bit of measuring but it fit first time!
Once it was all plugged in I connected the IID tool initially I had a radar CAN bus fault, after rechecking everything I realised I had the wires the wrong way round!
Once that was fixed I enabled some options in the extended CCF file, you’ll need to ask Patrick at GAP for the full access…
I went to calibrate the cruise control but initially the option wasn’t there, an update of the IID tool fixed that, then I kept getting an error when trying to activate the calibration, again Patrick & team to the rescue with a beta version of software and the calibration started with the adaptive cruise control light flashing, after a 7 mile drive on the twisty Somerset roads the light went out, ignition off for 15 seconds, started back up and just like that I have adaptive cruise control!

Thanks to this board and all diy-enthusiats here.
A was able to finally fit all the needed parts in my L320 Range Rover Sport.

I was also able to edit my CCF with JLR SDD + Mongoose Clone Scanner.

Works like a charm now ❤️
Special Thanks to loanrangie for sending the stl-file to 3D-print the bracket.
I overworked it a little bit, to fit better.
