First post so bear with me folks... coming from the VAG group, the BMW electronics platform seem to be a lot more logical. The same cannot be said for how the option lists are put together.

For those of you still in need of a blind spot function that's an option for other markets NA,MEA,SA and RHD countries like Japan and Australia, the UK & Ireland market have been left out The UK&I Market does however come with Lane Assist as standard.

Active Cruise I can understand that there are risks with a manual gearbox, however VAG cars came with this option in a manual from the 12's - 20's without stop and go. It just prompted you to shift in the dashboard when needed.

This is an IN PROGRESS guide to exploring the parts and wiring before comitting to buying the parts. To cover the predictable comments heading my way....eg "waste of money and waste of time", "buy an auto", "if you want the closest to an analogue car, then why?" please leave this at the door.

What I will appreciate is people who are intrigued, curious and also helping others who might want to explore this as an option. Also anyone who has this specc'ed already on their UK car, would you mind helping narrow down the parts for the UK spec as there are a few options (whether parts supersessions or UK/EU law specific parts for radar frequencies etc.)

One rumour I've come across and the wiring diagrams would support this, BMW seem to use the same wiring harness for pretty much every variant of a car. If this is true, you have no idea how much less pain this means to any retrofit exercise. The opposite is true of VAG cars.

So to begin......

Option Codes / S Codes / PR Codes?? Still working out BMW's nomenclature->

• S[2MA]A Manual Transmission
• S[5AS]A Driving Assistant
• S[5AV]A Active Guard
• S[5DF]A Active cruise control+stop&go function
  Sub Categories:
• S[ZN1]A Active Blind Spot Detection
• S[ZN3]A Frontal Collision Warning w/ City Collision Mitigation
• S[ZN4]A Lane Departure Warning

ACC Active cruise control I'm in two minds with, given if the car wants to slow down, being stuck in 6th could be problematic. Stop and Go won't be something we can have coded in either. So either there is a hardware variant without Stop'n'go or it can be coded out.

from BMWUKriving Assistant is a camera-based driver assistance system consisting of:

- Lane change warning with active return: monitors the zones to each side of the vehicle, detects vehicles in the "blind spot" with a flashing symbol in the exterior mirror.
- Approach control warning and person warning with city braking function
- Rear crossing traffic warning with additional real-image display and brake intervention.
- Rear collision prevention, which detects the threat of rear collisions via rear sensors and warns the traffic behind via the hazard warning lights.
- Speed Limit info with no-overtaking indicator and manual Speed Limit Assist.



Parts:

Blind Spot Monitors X 2 - 3 options (maybe specific to each market?) I don't know what Z or AE is? rest of world? AE-America/Europe?

It's not difficult to make your own harness, but I am wondering how much of the existing harness will already have the connectors but just coded out.

for those that may just want to buy in a harness....

Rear Bumper Cable Sets - Unknown if change required?

61 12 5 A4C 9B4 Cable set front bumper



WIRING - Work in Progress

Component IDs

B465 - Front Radar Sensor
B149B - Rear Right Radar Sensor (BSM)
B150B - Rear Left Radar Sensor (BSM)
A29_A - Driver Mirror LED
A73_A - Passenger Mirror LED
F209 - Fuse for BlindSpot Monitor Side Assist
F208 - Fuse for ACC - Front Radar - Active cruise - > may also be shared with lane assist?
F67 and F68 used for Exterior Mirrors but no adjustment looks required. Maybe a bigger fuse once installed?



CODING in E-SYS - Still familiarising myself but having done this on vag cars, my first guess is the below modules:

Gateway? Add in the BSM and ACC modules?
ABS ? Tell the Brake ECU that the above are installed?
Cluster/Kombi - Tell the Cluster that the above have been installed?
Suspension -
Existing Cruise control -
Steering Wheel -
Start Stop Module -
Rear View Camera - for RCTA enablement
Parking Assistant - for RCTA enablement
Infotainment -
Lane Assist -
Transmission -
AirBag -
Central Electrics
Engine -> to prevent Stop & Go?
BCM - Determine the CAN and add where appropriate.

and Code the actual ACC and BSM modules themselves?

I'll post the coding in due time.

It's probably worth mentioning my car is in transit, so until it arrives, there may be a delay on the updates

Please feel free to chip in or flag anything else that may help the common cause

The most important thing is to figure out the options coding of each of the module that is required to support ACC. Camera, radar, instrument cluster, engine controller, idrive, steering controls and the brake controller.

This may be an impossible task if for example the ACC control unit expects the transmission to provide gear information as "D" (drive) to activate ACC which is not possible in a manual unless you create a proxy module to duplicate the automatic transmission messages.

1st step would be to understand what is needed to retrofit ACC on an automatic g87 without the ACC option from factory. That can give some definitive actions towards the goal.

Not to discourage you, but this seems too long shot to be worth the time.

Thanks for the input. To be clear it's not just the ACC I'm looking at, it's the wider scope of work on Blind Spot Monitors and RCTA which is currently a combination permitted (with a manual transmission) everywhere in the world apart from the UK.

On the ACC specifically though, you are right in what you've suggested, but I do love an experiment. it's about the journey not the destination.

Will keep you posted.

Good to hear. Looking forward 👌

Ok, So I have my wiring diagrams at the ready but TheNine90 has made me realise that if this is like FPA codes on VW (not to be confused with SFD) then we may need some artistic licence a little later down the line.

xps for awareness on file hunting can you confirm I've understood the naming conventions for file types below:

.swfl - Software File
.caf - ??
.cafd - ??
.ncd - ??
.fa - Firmware File
.fafp - ??
.0da - Parameter Files

Did you end up fixing lane assist to your car in the end?
