Robinasu. About those codes 63dd and 62d6 they are dsc interface. Only thing is to run longitudinal calibration to dsc with ista.
Now i have extra parts on stock. If someone need radar and ldm i can sell them. |

Nice
Guys, I'm loving all the activity here. Thanks for the updates. Today I received the ACC SZL and installed. When you swap out the SZL make sure the battery is disconnected when the airbag is disconnected.
Anyway, I got the SZL installed and calibrated but I still have the two DSC errors and sometimes the DSC complains about the pressure sensor but after I run the calibration the pressure sensor error goes away. I thought I reset the DSC long sensor, but maybe I missed that part. |

Hi Kissvesala, are you saying after running the longitudinal calibration and they should go away, or are you saying that is something to try? I ordered the new ACC DSC hydro unit and it arrives next week.

Ok

I also installed and wired the active steering module. The next time you are at the car it would be cool if you can note which SW is loaded on the active steering module and your DSC. When powered up, my active steering module complains a lot about the DSC. I did upgrade it to the latest software, but I'm wondering if that was a bad thing as I was looking in the daten config files and for platform ZW03 the last active steering software version was a couple ZUSB numbers behind the final ZUSB. Keep in mind I did not have the rack installed or connected and have not performed the active steering setup. I want to confirm the software will work before I drop the subframe. lol |

Another question I have is if modules must have matching VINs. I read something where the active steering module might check the VIN, but not sure about that.
Also, just to be complete, I swapped in $541 into the vehicle order to see what would happen - same two "vehicle interface" errors. It's so weird the ACC option needs a different hydro block in LCI cars. The $544 option already has the brake function, so it has a pressure sensor in there. ISTA-P seems to look at more than the VO as it initializes. The car integration level must be determined somehow or is saved on a module(s). I'll poke around the new hydro unit/DSC ECU when it arrives. Last edited by robinasu; 06-05-2020 at 03:59 PM.. |

The $5DF Retrofit is done
So i received today my FRM3R.
I changed it, upgraded it and coded it to my car. Then, i checked if there was fault on LDM and nothing : VERY GOOD. Then i try the car on the road and it works fine. ![]() So for doing this retrofit for a E70/E71 before 2011, we need :
Thank you for your help. |

Hey Poms, that is great. Glad you got it going.
My new DSC arrived but the junk yard got the part number wrong, so I still need an ACC enabled DSC hydro block. If anyone has an ACC DSC hydroblock/pump please let me know. |

how much does the SZL part number matter?
Here is a question for those of you who have gotten into this with a working ACC solution:
My question has to do with the SZL, steering switches/clock spring combo: ?Does it matter which clock spring assy you have so long as you have the correct cruise control stalk installed? For the LCI model steering wheels WITHOUT paddle shifters, I see 3 different part numbers listed and I can’t reconcile why there are three based upon the wiring diagrams. I see 61319203106, and 107, and 108. These are called out as different p/ns based upon which option sets you might have: S248A, S521A, S541A, S5ADA, S5DFA The only physical differentiator that I can see has to do with whether or not the unit supports a heated steering wheel option. The clock spring connector at the 4-o’clock position, or 8-o’clock if looking at the back, is different. I can’t see anything else different among the options. That connector appears to go with the clock spring and the ACC cruise stalk uses the same connector that all of the other stalks use, which appears to be the same across all p/ns. Can anyone confirm if one can keep all other pieces intact on the steering column and install ONLY the cruise control stalk with the ACC adjusting wheel on it?

I only replaced the SZL and reused the clock spring and it worked. That SZL was most likely from an X6 and I have a X5. Also, I actually removed the original cruise stalk from the original SZL and replaced it with an ACC stalk. You have to factory code the DSC since it handles the SZL comms. Works fine. I sold the “ACC“ SZL I bought with the original non ACC cruise stalk.

Great Success
Ok, just to close the loop - I have ACC.
![]() I finally installed the new ACC DSC unit. With the E70 X5d, do yourself a favor and rotate the upper intake pipe to the other side of the oil cap. You can pull the DSC out there while holding the hydraulic pipes aside. Also, drain the brake fluid from the master cylinder reservoir or it will completely drain when you remove the pipes from the DSC unit. I did not pull out the entire DSC bracket- just removed the two bolts on the bottom of the bracket that secure the DSC unit to the bracket. I tried vacuum bleeding, but I'm not a fan. It draws too much air through the caliper vents and you can't gauge the amount of air in the line. I wound up having a friend pump the pedal while I manned the caliper vent, then activated the abs pump bleed function a couple times at each wheel. The brakes feel great. I don't think the last shop did a very good job, but the old fluid was clear. ACC is great. Very happy with it. My active steering project is progressing. The only errors left are from the EMF (parking brake). It complains about the DSC interface after I code $217 for AFS. I've read the EMF can be finicky and there is a workshop mode. I will have to play around some more. Anybody have any hints? Also, does anyone know if the ACC radar must be calibrated for best performance, or does it only need calibration if it complains? A big thank you to everybody in this thread for your tips and hints! Last edited by robinasu; 07-18-2020 at 02:57 AM.. |

Follow-on question, did you need to do any additional wiring relative to the steering assembly in order to get a physical link to the comms network? My guess is NO, but I would appreciate confirmation. |

Can you do ACC S541A w/o the hydro unit?
In terms of comparing
is it possible to setup S541A, ACC only, with all of the parts MINUS the hydro unit? That is to say I have the Cruise Control With Brake Function S544A and I am buy-ing parts for ACC. It looks like I will come up short on the Hydro unit and I would like to know if I can move forward and code S541A with the hydro unit I currently have? this post seems to suggest it is okay: Quote:
I have a late model x5 LCI any feedback is appreciated. Thanks again! |

Yes

-The SZL, which includes the stalks and the angle sensor -The clock spring, which may be different depending on the functions you have on the steering wheel (heated wheel, etc) I believe your existing clock spring can be moved to a new SZL. The clock spring has two connectors. One plugs into the SZL. The other uses the SZL as a mount and plugs into a loose connector in the steering column. I moved the clock spring from my X5 to the X6 SZL. I am guessing the clock spring part number depends on the steering wheel function options you have. The DSC unit is the gateway for the SZL, so if something isn't working right you can try to factory code the DSC using NCSexpert. When you code the DSC it "codes" the SZL.

It's hard to find the ACC DSC unit. Try eBay international sites, too. |

I understand better now; it has taken me several read-throughs of these posts and the TIS diagrams As I said, I see 3 different part numbers for the SZL assembly: 61319203106, and 107, and 108. These are called out as different p/ns based upon which option sets you might have: S248A, S521A, S541A, S5ADA, S5DFA In my case I need the part number ending in 108 but I ended up with one ending in 106. My plan is to reuse my clock spring assembly OR switch the cruise stalk from the 106 SZL I ordered with the one that is on my car already. I need to get my hands on both and compare them to sort out the differences. All of the SZL assemblies appear to have the same 12pol connector on the back, and then the clock spring has one of two different connectors depending upon options. I have not been able to reconcile why there are 3 different p/ns for the SZL module. parts link for LCI minus the paddle shifter is here I guess I will figure this out, eventually Finding the Hydro Unit has been tough, but I will need to keep looking |
