Hi Colin,
Reading through the first few pages of this topic, I did not see much use for a D4 steering wheel in my D3 until I read that it might be possible to fit ACC to a D3. If you have more info on that I would be most interested. ACC is a feature I would love to throw some money at.
Cheers,
Bernd

Hello berndv, fitting the switches is one thing and in fact quite easy as you can just choose the with ACC option in the Microcat as i did, even with the origional D3 wheel.
But for Full working ACC you need the ACC ECU and associated wiring, the 2 K's worth of radar sensor mounted in the lower bumper and it all enabling in the CCF.
The sensor and bracketry is availaibe for the Sport but not it seems for a D3.

Still sounds interesting but might be a bit too complicated for a DIM (Do It Myself ) job.
I tried to source some parts in Microcat (april 2009 version) but the search function puzzles me a bit.
It can't find a single part with the word 'adaptive' in it (with and without partial search on), where clearly there are parts that have the word in it.
Was hoping to find out how the various bits looked like and how much they would set me back. if the bare radar sensor is 2k, the ECU and other bits and pieces needed would probably cost a small fortune as well.

Well it's time i posted another progress update on this project.
It's gonna be long, as we are nearly there and i have a lot of detail to pass along, so if you ain't interested, don't bother reading any further.
A few un forseen factors have really crippled me time wise recently, but non the less i am in so deep with this mini project, that i really need to get it finished and so, by some miricle and a lot of delagation, i have managed to find yet more time to put to this project.
The great news is that it is so very nearly there now, that what i have left to do is more formality rather than further experimentation and development into the unknown.
The logic for inputting the 2 paddle switches and 2 ACC buttons (optional) into the transmitter circuit is working perfectly, and the receiver picks it up and provides a data stream that i will be able to later use to shift gears and hopefully do something with the EAS heights. Initially the transmitter was being powered from the heated wheel supply, as there is no power feed into the wheel. However i wanted to try and find an alternate way to power the transmitter, so it could be implimented on non heated applications too, but did not want to rely on fitting a battery if i could possibly help it.
To achieve this has certainly not been easy by any means, and has required a degree of thought, cunning and innovation that has left me feeling really very smug and frankly, I am still quite stunned and in sheer dis belief in that i have actually got it to work at all. But work it does and blooming nicely too.
So other than a few tweaks and a final prototype build, which should really only take about a week, i am at last finally there and can soon proceed to production and supply to Beta testers.
I can therfore now give more detail into the physicality aspect of exactly what will be availiable in respect of the first 3 parts that will be availiable from the start and what i expect to then be able to make availiable shortly afterwards.
First off will be a base conversion kit for a pair of standard D4 / 2010 on RRS wheel switch packs doing pretty much what you see in the video i linked in an earlier post on this thread, namely all regular Audio and Cruise control functionality. These will be very easy and simple to fit by anyone and will include full how to instructions.
Second will be a seperate add on kit that will simply plug straight into the base conversion and will support heated D4 / 2010 on RRS steering wheels. Of course the switch pack will need to be the type that supports the heated wheel too.
Third will again be a seperate add on kit that plugs into the base conversion and will support the two additional buttons that are only currently used and really required for ACC equipped vehicles such as the RRS supercharged.
For anyone not sure what this means, the ACC version of cruise control is different to the standard one in that it has a radar sensor mounted in the lower front bumper that can lock on and maintain a fixed distance to a preceeding vehicle. Mercedes call this Distronic. the steering wheel buttons for controlling cruise on ACC equipped vehicles has all the regular buttons, but in addition, there are 2 more marked <-> and <---> which are so that the user can adjust the distance to the preceeding vehicle to be greater or smaller.
Although the Dealers IDS lists the system as applicable to Disco 3 ,it was never fitted to my knowledge and the Microcat lists no parts for it on a Disco 3 except, interestingly enough, the steering wheel switches. Go figure
When i added wheel switches to my own D3, i chose the "with ACC" version and so have these buttons, but of course they presently do absolutely nothing at all, as my D3 does not have ACC cruise but the standard one, just like everyone elses does.
However as i shall explain, i have a cunning plan to eventually use these additional 2 switches for something quite different, and as such, for anyone buying a D4 wheel to convert and put in a D3, there is a good reason you might want to opt for the "with ACC" switch pack.
Fourth, i expect to release an add on kit before too long that will support the 2 paddle shift switches, so if you will want that, you best get a wheel wihich supports them to start with.
As stated, this is no hope or wish that may or may not materialise and i have spent as much, if not more time in the development of this particular option to make absolutely sure that the base kit will support it from the start.
As such i have already fully finalised the design for the transmitter part of this kit and built a receiver that at least gets the data, but is not yet finished and is the only bit i need to complete to make this fourth option availiable.
So i can tell you a little bit more about the physicalities of it, especially the transmitter part, even at this stage.
The transmitter part of this fourth option will plug into the base kit where the ACC kit would. When fitted with an ACC Kit, this then plugs into the transmitter instead.
The transmitter has some user selectable jumpers on it, that can be used to configure it in one of two ways.
The first is to set it so that the ACC buttons are pass through and can be used to control the ACC distance for anyone who has ACC fitted to their vehicle.
The second, default configuration is to feed the input of the 2 ACC switches into the transmitter such that they can be picked up by the receiver when pressed.
As stated i have built a prototype of the receiver part of this option, and have the data stream telling me which buttons or combination of them are being pressed, however in order to concentrate on getting the first 3 parts finalised and into production i have elected to leave the final stages of development of the reciever till afterwards.
The plan is to add a microcontroller, space for which is already provided on the current prototype. This will read and interpret the incoming data stream and will, when receiving data telling it the paddle swithes ae being pressed, control the Auto Box control lines just as if you were in command shift mode and manually shifting up and down respectively, thus giving paddle shift tiptronic type control, exactly as per the 2010 RRS equipped with this option.
The receiver is physically very small, about th size of a box of matches and currently has a stubby helical coil whip antenne on its end. It will need to be tapped into 12 V power and ground and 3 Auto Box control lines, and so is likely will go somewhere near the Autobox ECU under the bonnet, which we will work out and document.
Finally, and as promised, i should explain about the ACC and why i suggest fitting the switches even if you do not have ACC on your vehicle.
Also already provided for on the Prototype receiver board, is the fitment of a CAN tranceiver circuit hooked up to the microcontroller.
It is my hope and intent to add code to the microcotroller such that it takes the input of the 2 ACC buttons marked <-> and <---> but in the case of the D4 / 2010 on RRS implimentation is printed 90 degrees out and so looks more like raise and lower buttons, to do just that diagnostically over the CAN bus. I plan to impliment the plus and minus 25mm offset being applied by each button respectively, and a return to standard simply by noting when both buttons are pressed at the same time.
It is early days for this yet, although i am quite sure it is ultimately do able and having got the first 3 stages completed and in production should be able to spend the time required to make it happen.

Hi Colin,
Is there a way to encourage you to fiddle out how ACC could be made to work on a D3. i.e. what parts are needed and what needs to be done to connect it.
Off cource the need to activate the ACC in the system would be a fine excuse to buy one of your beatifull devices.
Cheers,
Bernd

You simply need to fit an ACC ECU and its associated Radar sensor into the lower bumper and wire it up to your D3 as it is in the RRS, Have the with ACC buttons and then enable it in the CCF.
Like i said all the parts would have to be sourced via an RRS.

I hoped to find the answers in MicroCat (Apr 09 version). Spent over an hour browsing through the RRS section searching for the ACC ECU, radar unit and wiring harnass, but the only ACC related thing I found, is the button assembly for the steering wheel. The search funtions seems useless as all buzz words like 'ACC', 'Adaptive', 'Cruise' etc returned nothing usefull.

I spent 2 minutes of which 1 minute 40 was spent waiting for windows and microcat to load, and came up with these
YBD500560 = sensor
YWU500171 = sensor mounting bracket
NNW501922 = ACC ECU
SCU500010 = ACC ECU mounting bracket
In fairness the search is not very good, i always browse through the pictures at high speed.
If you search any of these with it set to part number you will find it all on the same page.
