Retrofit 5DP Parking Assistant
Finally got around to writing this up.
I did a fair bit of research using online parts diagrams (real OEM) and Rheingold for the wiring diagrams. The most difficult part is making the wiring harness and extending the existing wiring harness. Also note if your car already has PDC, the new PMA unit will now control the PDC sensors as well so they will need to be rewired from the REM module to the PMA. Heres all the parts needed to do it: PMA UNIT 1 x 66336864898 Control Module (PMA) 1 x 66336854515 Bracket for PMA (No needed if you have trailer hitch) 2 x 16131176747 plastic nuts to secure PMA holder 2 x 61138364666 PMA connector housing 2 x 61138364662 PMA connector cap (this part doesnt really fit but its as close as I could find, you have to break off a tab on it to secure the plug in) 8 x 61130005197 PMA connector pins (these come crimped onto cables already) PMA SENSOR 2 x 66209317887 PMA sensors front (part no. is for B50, pick right p/n for your color) 2 x 66206923000 rubber grommet for PMA sensors 2 x 61136925599 Connector housing for PMA sensors 6 x 61138353705 Pin Grommets for PMA sensors 6 x 12527545857 Pins for PMA sensors WIRING HARDWARE 20-30 metres of 0.5mm cross section wire. Preferably different 3-4 colors for ease of identification (I made do with 2) 1 x 61131378906 Power pin for rear fuse box 1 x 61131387140 Ground pin for rear chassis TOOLS Soldering gear Molex Crimp Tool I used the one I had from making custom PC cables Knipex Stripper highly recommend one! Tesco Cloth Tape for OEM look and finish Sensor Install Take your front bumper off (plenty of guides out there). There will be a X marked where you need to drill for the PMA sensor right above the Sideview Camera (if you have it). Drill from the inside out using a 18mm step drill bit. Its very soft plastic so super easy to drill. Youll need to pull off the existing bracket glued to the bumper to drill the hole, replace adhesive with some 3M VHB tape. Wiring Make sure you know which wire corresponds to which pin on the sensor. Run the wire from the sensor up to the firewall on each side of the car. This is quite tricky in the F8X due to the strut brace which will need to be removed. Follow the path of the cable for the sideview cameras. Once in the car, route the left sensor wire across the carpet along the front to the right hand side to join the cable from the right sensor. Run this along the carpet under the B billar(sedan) and through to the boot, next to C pillar. Power The power for the PMA unit will need to be sourced from the rear fuse box. Connect the power pin to a free slot in the K15 (switched power) block under the fuse box. BMW recommends F146 but mine was used already so I used another one. Ground The recommended grounding place for the PMA is the block right under the rear right seatbelt. Connect the pin to a free slot on this block PMA sensor wires The PMA sensors share a power and ground cable with the front parking sensors. With the clip facing down, the middle wire is the signal wire, left the ground and right is the power. With the 6 cables routed to the back of the car. The 2 power wires join together with the front PDC power wire. The 2 ground wires join together with the front PDC ground wire. And the middle signal wires go into the respective pins on the PMA unit. REM unit Each signal wire for the existing PDC sensors need to be removed from the REM plug and rewired into the PMA unit. There are 8 in total (4 front and 4 rear). The power and ground for the front and rear sensors also need to be moved (4 in total). So 12 pins need to be extracted! The connector block with all the pins is in A174*14B this is the longest block of plugs on the REM (brown plug). The pins that need to be removed are: 36 ground 37 ground 38 rear centre right (needs to be extended to reach the PMA unit) 39 rear outer right (needs to be extended to reach the PMA unit) 40 front centre right 41 front outer right 48 power front sensors 49 power rear sensors 50 rear outer left (needs to be extended to reach the PMA unit) 51 rear centre left (needs to be extended to reach the PMA unit) 52 front centre left 53 front outer left 2 wires need to be added to connect the REM to the PMA unit. These are the K-CAN wires and ideally, they should be a twisted pair. They go into pins 29 and 44 on the same REM plug. PMA unit There are 2 plugs that go into this unit, 2B and 1B. Refer to the picture to see which one. Basically if the wires point towards the right, 2B is left connector and 1B is the right connector. 1B: 2 36 from REM 3 48 from REM 4 Power from rear fuse box 10 PMA sensor right 11 PMA sensor left 12 52 from REM 13 40 from REM 14 41 from REM 15 53 from REM 2B: 2 49 from REM 5 37 from REM 11 connect to 29 on REM 12 connect to 44 on REM 13 39 from REM 14 38 from REM 15 51 from REM 16 50 from REM Programming If you have a new PMA control unit, you will need to program the module with the version of psdzdata you have. This is done the same way as you would if you were upgrading your ECU modules with the latest psdzdata. TAL-processing. Coding Lastly, you need to add 5DP to your VO and VO code the following modules: EPS EGS (not needed on DCT cars) DSC FEM ICM KOMBI HU-NBT REM And youre done! When I first tested this, I realised Id wired some sensors wrong. Just make sure you connect to the right pins and all should work. Next up is to see if its possible to install 2 additional rear PMA sensors to make perpendicular parking work (like on the F30LCI). The pins are already available on the PMA control unit 17&18. |

Nice job!
How much was the PMA2 unit? I really wish I took this option on my F23 and F30 LCI as it's only $400.

My picked up last Friday my new bmw F30. I have the options:
Surround view Rear/front PDC Rearview camera Active cruise control Lane change warning(blind spot detection) Speed limit info HUD Do you think I can code the parking assistant? Or do I need the servos for the steering wheel to turn? |

Nice job! Looks like I took too long to finish mine up, I'd been working on this since last year but got busy with work/life and just finished it on my car, and was working on my write-up when I came across yours.
One question(may be related to x-drive vs non) was how did you not have to replace the DSC Pulse Generators that go to the Front wheels? I had to replace these on mine as I did not have the ACC feature, and per Realoem, those need to be changed as the part #'s are different for cars with ACC or Park Assist. EDIT: Found the reason. M3/M4 only have one type of pulse generator for the front wheels. Non-M3/M4 cars require the replacement of this part. Last edited by roxxor; 12-12-2015 at 05:20 PM.. |

Hi all,
Thanks KKS for the detail on this retrofit, I have finished the 5DP retrofit on a F20, its working great Now I would like to know if anyone successfully convert this to support perpendicular parking and auto-PDC? "...Next up is to see if its possible to install 2 additional rear PMA sensors to make perpendicular parking work (like on the F30LCI). The pins are already available on the PMA control unit 17&18..." I have tried replacing the PMA ECU from preLCI to LCI, attached 2 extra back PDC sensors to pin 17&18 and VO coded. The auto-PDC works but when pressing the PDC button to call up park assist, it failed with error "D4167B - Message (Park 2 function activation, 0x31A) missing, receiver PMA, transmitter HU". It seems the NBT HU requires an upgrade. Before I flash the NBT HU, would like to know if there is anyone giving me hints on this. |

Thanks to you KKS and roxxor I finished my 5DP retrofit without much problem! Thanks also to Shawn and tokenmaster for sharing their software and knowledge.
I manage to install the sensors, wiring and coding using KKK and roxxor's write up of retrofitting 5DP although my car is a F20 116i 2013 almost everything was the same. Thanks again. Last edited by Raygbmw1; 01-15-2017 at 05:37 AM.. |

For my 2017 M3 with the same PMA module the front PMA sensors were switched around pin 10 was left and pin 11 was right. FYI. BMW AIR also showed this.
