The biggest cost driver is definitely the DSC and ICM units, since they're so rare. Even the radar sensor can be bought comparatively cheaply.

To echo what roxxor wrote, here's what the correct DSC should look like

Can you tell what Company's logo is on the bottom left hand side of the label as this Company makes the unit for BMW?

Sadly no, and that BMW is long gone from the dealer lot. Best chance of finding the company is to keep looking on eBay for an ACC-enabled unit, but then you run into the issue with DSC units of the mismatch between visible parts numbers and the corresponding one in the system.

Currently one unit is available on ebay: http://www.ebay.at/itm/ACC-DSC-Hydro...UAAOSwcUBYQDcD

[roxxor]

I saw that one, but I am still waiting for an answer to my above question about the differences between the designs. Would hate to make that kind of investment and then have it not be compatible.

Hi,

I am looking for a DSC before 07/13 in order to retrofit ACC: my car is 07/12

I did the replacement of the ICM, by a high version (retrofited adaptative suspension 2VL with KW DCC), now it is really difficult to find DSC with ACC feature

Price is 1600€ wo VAT from BMW dealer..

I may be off here, but doesn't ACC use an FSC?

[anom3]

BTW, a great way to find out what parts are "different" according to options is to use the following.

This is for my 11.2012 build F30 335i:

http://bmwfans.info/parts-catalog/F3...option?s=S5DFA

Notice the S5DFA... Replace 5DF with whatever option you like... 5DF is the ACC.

EDIT : So judging by that... The DSC is different as we all knew, but the brake lines are as well... Good luck swapping those Not a retrofit I would venture into.

[roxxor]

After almost a year and a half of searching... success!!!!! Now the real fun can begin!

[Abi]

Nice! Keep us informed.

[GCinFLA]

Just an update here....difference in DSC design of the 2 asked about earlier - most likely one is the pre 5/1/2013 DSC layout and the other the post 5/1/2013 layout.

And yes, Brake pipes would most likely need to be replaced as the bends would not be in the correct place. Running the brake pipes from engine compartment to rear wheels is a major task.

Finally, for the non-ACC post 5/1/2013 DSC to Master Cylinder, there IS NOT 1 in the USA...even though it's used on F2x,M2,F3x,F4x,M3,M4,F8x etc.

Other ways to tell them apart are that on the drum part, the base version says "DSC LK BASIS", whereas the ACC version will say "DSC ACC".

The above numbers are incorrect. Correct listed below. roxxor might have had fat fingers or wrote something down incorrectly.

ACC Control Box 34526869732
ACC DSC 34516869731

Non-ACC Control Box 34526869730
Non-ACC DSC 34516869729

These are for pre 5/1/2013 (or pre 7/1/2013) Contradictory info.

If you have a 2014 or newer, it would be different part #'s.

Those numbers should be rechecked prior to ordering, fwiw.

Great idea, let me know if you find the coding to do this.

Also do you find ACC braking in sport mode is very ruff and harsh? The only comfortable mode I find to use ACC on HWY traffic (accordion style traffic) are comfort (sometimes braking is still a little hard) and ecopro mode.

Some early model F30's had a combination ACC/Adaptive M Suspension ICM, so if you were lucky to have an early model M-Sport you may not have to replace the ICM, however after 11/2012 that was replaced with the ICM and ICM High. Like I said above, finding the correct DSC part number has been the challenge for me, I may start looking at local dealers to find a 2012/2013 F30 with ACC to go look at and get the DSC Part # from.

On the auction site, both the DSC and ICM seem to average anywhere from around $200-$400. Radar Units seem to be in the same price range, and the Driver Assist switch can be found for between $50-$100, so depending on what needed to be replaced, you could potentially get it done for less than $1k. Even if you do have to replace the brake Pipes, some of those parts have to be ordered from overseas, but you'll still only be looking at around $200 for those parts as well.

Hello roxxor, i am interested about adding acc in my f33 420d 07/2014. It is so dificult find de dsc with acc and the icm high module. I need to know if i can get a dsc, icm and radar sensor for bmw f3x with no coincidencies or matching with etk codes for my f33 b47 ece car. I mean if can work parts like 6864628 6865301 6861377.
Thanks for your help.

I looked all over my area for a used 430 with ACC. Couldn’t find one. I went without it.

Hello Rocco, did you change the brake lines finally?

[wilbur_the_goose]

For what it's worth, my "other" car has ACC (it's a Honda). Works great, but I don't think it's worth the money we're talking about here.

What I really dislike about it is highway driving. Let's say you're doing 73MPH (65 zone) - if you come up on a car doing 65, your car will slowly adjust its speed to 65 to keep the appropriate distance. You won't even notice it until you eventually see that you're driving slower than you want.

If you had that type of cash to spend, I can think of much better things than ACC.

Hi guys I recently bought ICM High for ACC from 01/2016 car and DSC from 12/12 car. Is it 100% confirmed that DSC from before mid 2013 will not work on car after mid 2013 ? What is the difference and how to differentiate it?

If you know some one who knows the answer please tag him... really need to know. If anything will have DSC ACC pre 07/2013 for sale with ACC Radar

[hkgans]

Hi Roxxor,

Any update on this? Did you change the brake pipelines too?

This retrofit is not doable (if you want you ca do everything). To begin like said you need other icm, dsc, and acc module, but yu also need to change or add a lot off high pressure cables, and you need to change the dsc cable on each suspenssion front l and r and rear l and r, price of the cable is 90 euro piece. And last but not least this is a securitie option so recuiers a fsc code so even if you get it installed it won't work

[hkgans]

I'm confident that the DSC with a black drum is MK60 model while the one with silver drum is MK100. MK60 is preLCI and before 2014-3 while MK100 is for model after 2014-3 (correct me if I'm wrong). The pipelines configuration on these 2 DSC models are different, so it will be difficult to put MK100 into cars that were made before 2014-3.

Some Russians have managed to retrofit ACC onto their F30s and one of them installed MK100 onto his preLCI (link https://www.drive2.ru/l/472884559017411012/ ). I don't know if it is illegal use those union connectors in my location.

I'm still in the process of acquiring parts for this project. I would say this retrofit is doable though very difficult because finding a reasonable priced ICM High and an ACC DSC is nearly impossible, and secondly you have to replace/alter hard pipelines.

[yoodog]

not that simple. mk60 big drum one is used on pre lci till 07/2013 incl. After that date bmw switched to mk100 version till the end of pre lci f30 production and for all lci f30 production. SO mark date is 07/2013 not LCI or Pre-LCI
