Before retrofitting the surround view option, I thought once I was done with it that would be it, I would stop right there. But 2 weeks later, I found myself looking for ways to add ACC because I use cruise control a lot and having the system maintain the distance while making sure to go back to the set speed as soon as possible looks very interesting to me. So I've gathered the parts I think I would need but not sure if the list is complete(Mine is a one with M Sports Package):

1. ACC Sensor- 66316885585
2. Air grille - 51117903901
3. Sensor bracket - 66318047453
4. DSC unit - 34516876917
5. ICM - 34526886191
6. Steering wheel switch - 61317849406
7. Switch panel-61319279306
8. The wiring

My questions are:

1. Does this list miss anything?
2. What is the part number for the sensor wire? maybe I need to build it on my own?
3. Where do I tap that wire?

I was under the impression that you needed the KAFAS2 camera etc. installed to have ACC and the retrofit for that requires a new windscreen, unless you already have that?
And a calibration at a dealership, but maybe it's possible to do that at home?

Yes, I've just realised that I need Kafas and yes I don't have it. I'd love to install Kafas because it gives you lots of new opportunities but replacing the windacreen ia what keeps me from wanting it.

So sad to have to cancel the project

Yeah I'm in the same boat, very expensive to sort. Shame really!

Your list is complete. You just need to build your own and run wires. Not many wires so it’s pretty easy. I have all of the parts and plan to do it once my schedule is better.

I did retrofit KAFAS2 previously. It’s not terrible. Most expensive part was the windscreen.

I've newly learned that I need Kafas, in my case Kafas2 for ACC to work. But, but. A friend of mine who has an F30 visited me today. The car hass ACC. But it has no Kafas. Trust me it doesn't have it. I looked over and over just to make sure it's really not there. What he has is an FLA camera, that's all, but that's for the HBA only, isn't it. I took his car for a drive just be sure that ACC really worked, and it really does work as expected. Now, I'm a bit confused, if ACC can't work without Kafas, how does it work in an F30 without Kafas?

Could you please explain the wiring? How you built it and how you routed it.

ACC module have two S-CAN wires. Those two wires run to the KAFAS2 and ICM module

Hoa Do you have any ideas regarding this?

FLA is just for HBA.

I checked and F30 FRR run directly to the ICM. It’s different from our cars. I’m also guessing it can’t keep you in lane because your friend doesn’t have lane departure

Ah, then it means the Kafas is for Lane Departure Warning, which seems to kind of be offered in conjuction with ACC in F10s. In other words, in F10, if you have ACC, you surely have LDW as well. Is that correct?

Yes, at least I haven’t seen one that have ACC but didn’t come with LDW

I retrofitted ACC in my e70. Wiring harness can be built by following the BMW wiring diagrams. The connector is also not hard to get for the ACC Radar. I don't believe ACC requires LDW or Kafas. My e70 has neither but the front radar is essentially the same as F10.

TBH, I also think that if I just route my 2 S-Can wires to the ICM module, the basic functionality of the ACC will work. After all, LDW is not dirextly related to ACC. In the wirng diagram, it's clearly seen that S-Can wires from both the FRR and the Kafas then merge and conect to ICM.
True, I'm not sure if the computer is going to complain, as it seems ACC and Kafas are bound to each other. We'll wait and see what others have to say about this
