Essentially what you need is:

ACC radar
ICM High
DSC Mk100 “ACC”
ABS sensors
(Brake lines)
Bumper modification + brackets
Steering wheel buttons
Cabling

Because of your Drivers Assistant Package, you may or may not have some component already, but in principle is ACC independent from the Drivers Assistant Package.

Thank you Jimmert; I also have the Adaptive Suspension to complicate things further.

From what I understand at this point I would need the DSC and ICM to come from a car that had the Adaptive Suspension, is that correct?

Thank you!

HI there, i currently have a F30 without kafas.. can i retrofit the ACC 5DF option without having to get the kafas installed ? thanks

Yes i retrofitted ACC and dont have kafas. You get radar driven FCW with the acc.

Hi,

I would like to start the process of retrofitting ACC to my 2012 F31.
Can anyone please confirm if this is the DSC that I need?
Seems that is coming from an F10 2013.

Thanks in advance,
Alex

Theres two types of DSC's-with different hard line attach configurations. Check your current one to make sure the hard line attach points are in the same configuration.


Also check realoem to verify part number compatability.

Hi man, no absolutely wrong. f10 dsc is NOT same as f30, regardless of acccor not version.

+41784057964 my WhatsApp- send me a message, I can help you get all parts needed for Acc retrofit. We have done 2 f10 Lci and 2 f3x in December (parts takes time to arrive, about 2 weeks)

Total cost of the main Acc kit around 1250€, but complete kit with wires pins buttons bumper cover comes around 1600€

If you want remote coding or general remote retrofit support we also can guide you through (I already have all aspects for retrofit memorized haha, ever since my own f36 Acc retrofit)

Hi guys, I’m planning to retrofit ACC on my car. My car is F30 330i come with adaptive suspension and ICM is v7.3 pn 6867170. Do I still need to change my ICM in this retrofit? Thanks!

[TheNine90]

You need icm high. Check https://www.realoem.com/bmw/enUS/select for correct part no.

That part number is not used for the ACC Option SFD5A so it will not work

For my pre 7/2013 car, can anyone tell me if I spent way too much on a new control unit and swapped it onto my existing pump/valve block, would it work? I do see that the pump/valve block are different part #s between ACC and non-ACC but how might the mechanism vary between the two? Could it be as simple as the silly sticker being applied that says "BASIS" vs "ACC"?

The sticker is not Silly.

Basis is NOT for ACC cars. It’s literally telling you what it’s for.

Pre- 7/2013 are also different configurations as has been noted above.

Not trying to be a pest here, but it seems to me that, at the very least, the motor is likely the same between the two. I’ve seen units from older bmws (e90, e60) with the same black motor housing dismantled on YouTube. I’m having a difficult time imagining how this would vary from basis to ACC if it looks the same across multiple models and model years.

Then there’s the valve block. This seems more likely to be different somehow, but the question is how exactly? How might the valve block’s job differ between a basis and ACC unit? Are the passageways machined differently? Are the springs and valves different sizes? Solenoids of some different variety?

Given the difficulty in finding these units, I’m just trying to think outside treating them as black boxes with #s printed on them. A part numbering scheme was utilized to label and identify all the pieces of this assembly. My idle speculation is that in the process of denoting an ACC vs Basis unit, a different sticker might result in a different assembly part # because it’s paired with a different control board, as opposed to different control board AND valve block/motor. If you or anyone else knows detail about the mechanical/electrical/hydraulic differences between these units, I’m very curious to find out.

[YASBBYM3]

It’s a different control board, the wheel sensors are different (and they supply different info to DSC) and the actual brake piping is different.

I believe this is the correct part. I think whoever is telling you this came off an F10 is mistaken.

Just popping in here as I found some interesting differences between the F15 & F30 coding. (trying to work out if I can retrofit a radar for F48)

Does someone happen to know what the difference between cruise control in F15 and F30 is. I mean in practical terms.

It looks like one can just 'upgrade' the F30 to ACC_premium by coding, but unsure what the heck the difference is between them.

I mean the value from FRR (radar) is KAFAS available is set to 00 on F30 while it should be available as the car I am taking the values from have SLI. So why the heck is KafasAvailableBit not set too 01 on F30? Does that mean not all functionality in the F30 is utilized. If so, what does this mean in practical terms?

One thing I managed to find out is the abstandsinfo_funktion, this looks like related to this. https://www.bimmerfest.com/threads/n...mation.674526/

Does anybody know what Ibrake 5 & iBrake 6 is?

Anyway this is just a snapshot of my WIP sheet, but if there's interest I can share more about this.

[Jimmert]

KAFAS is the camera system under the interior mirror right? The F30 doesn’t use (any) camera for its ACC, only the radar in the front bumper. So regarding ACC, KAFAS does not need to be enabled/present.

But why not use it? Apparently X5 F15 uses it, so it must enhance the experience or?

Same with stau_erkennung(Traffic Jam recognition), why is that disabled on F30. I mean KAFAS hardware for the F30 is same as F15.


BTW, My X1 F48 has KAFAS only ACC

Its an interesting question; F01,F06,F10,F30 (and possibly more) all require radars for "Stop&Go" ACC enablement. You have to think, if it was possible to enable this feature without extra hardware, why wouldn't BMW have done so?

I think you'd have to look at the "system" has a whole, so, KAFAS, DSC, and ICM to glean why one can work without radar, and one can't. I would infer its some limitation of the DSC/ICM shipped in these cars vs others, if its true what you say about the same KAFAS being used.

Maybe wiring diagrams of the ACC system on the respective vehicles would offer some insight.

I did heavy comparison between, F15, F30 and F48. Planning to blend F10 or F01 LCI also in the mix to get full overview. (5 series F10 shares technology stack as with F01 LCI 7 series) even glanced sometimes at G30 to get an idea which way the code is moving. Also in terms of release years of a specific vehicle.

My conclusion is that I see no reason why I wouldn't work. Especially if you have ICM high & DSC ACC on F30. Coding parameters are mostly in all of them. Interesting to see is also if you look at G30 parameter and the introduction of SAS2 that you see how BMW is moving parameters around.

Some interesting observations:
- 7 series has both seen the old radar & the new radar but other components are the same and interchangable.
- FEM or BDC doesn't really matter as BDC is just same as FEM+REM, all the paramters are the same.
- Kafas is the same
- SAS in F48 replaces ICM and interestingly enough, is that DSC parameters on F48 are set on inactive while these are enabled on SAS. This means the same parameters exists in 2 different places but only 1 is active.
- From a mechinical point I see no problems, I mean as you have the MK100 the vehicle should be able to brake to standstill (which is I think the most important factor). supported by this brief description of Conti: https://conti-engineering.com/components/mk-100-esc/.



Another thing I find interesting is that:
If you look at the timeline when BMW was releasing cars & developing this feature it's within 2012. See page 27 in attached PDF about F01. That is right after F30 was released but with I step updates I think those parameters trickled down to F30 but never were enabled. Besides BMW is not afraid of not enabling things on lower series for keeping it exclusive for higher series. Why would BMW improve the ACC of F30, how do they earn money on that?


I also attached FRR_01 functional description. Which has some interesting remarks about ICM, that it is not used on X6...

The big question here is still, what is exactly the difference between ACC_premium & ACC_sng? I mean I cannot really see a practical difference otherwise that I think the premium should be a little bit more smooth or something. Especially the KafasAvailableBit got me thinking. The ibrake thingy, not sure what iBrake5 and 6 is but it should be something to do with emergency braking. Which I think has something to do with standing objects.
See this press release about iBrake6 on the RollsRoyce:

The iBrake 6 function uses information from the radar sensor and front camera to help the driver stop quickly and with maximum efficiency should an emergency situation arise. Working with the early or late crash warning system, the pedal reacts to the force applied to it, pre-filling the brake pedal and reducing the amount of pressure required to brake suddenly.
The system also alerts the driver with a series of warnings, urging action via the head-up display and on-screen. If no action is taken a further audible and visual warning is given. The active third brake light also flashes under emergency braking.

It's also mentioned in this pricelist/optionlist for 5 series 2016 as 5AT (use google translate, I don't speak italian either)



Anyway feel free to look at my working sheet: where I am trying to determine which FDL parameters are affected on the various models trying to make sense of it all. I started this all for enabling Radar on F48 as the kafas only ACC is really sensitive for the sun which makes it sometimes useless if the sun is not behind...
Note this is work in progress and have to do the F10 / F01 LCI codes aswell to really understand what is going on.
