Retrofitting PDC (Park Distance Control) + PLA (Park Lane Assist)

[George Kost]

One the first page of this topic, there are the wiring diagrams by @samisnake.
You have to study those mate.

If you don’t have rear PDC as I didn’t it is doable between 300 to 500€ depending on how easy you can find parts.
sensors are about 15€ each. Need 10 of them.
Module around 50€ used.
Cabling depending if you buy from Kufatec, or used. Maybe less than 100€.
Buttons 10-20€ each.

I had to source parts from different sellers so I had a lot of postage cost as well.

One of my best retrofits I have done!

Like to add to that, https://bm-parts.nl company near me, they have so much high quality retrofit sets and stuff. They also ship to other parts of the world.

Hello. I am currently retrofitting PLA2.0 on a3 8p МУ2012 with module 3AA919475L and 4 PLA sensors - two on the front bumper and 2 on the rear bumper. I want to ask if someone can explain to me how the system should work. Because when I engage reverse gear, the front sensors work normally, but the rear sensors don't always work. Sometimes only when I get within inches of the car behind me does it start beeping. Could it be that the rear sensors are not compatible with this unit? I don't know the part number of the rear sensors because they were OEM with the car. front pdc sensors are 1s0919275, pla sensors(front and back) are 1T0919297A. Also another thing that I don't know if it should be. When the car is in neutral the front sensors seem to beep correctly, but sometimes when the car is not moving and there is an obstacle in front it starts beeping on average and then gradually decreases the beeping and stops. Another thing, when there is an obstacle to the rear pla sensors, where should the beeping be heard from? because for me it is heard from the speaker for the front sensors.
Could something be wrong with the sensors being wired to the module? Or a problem with the module?
Any suggestions would be helpful. Thank you.

 

[George Kost]

I think the PLA sensors are only for park assist.
Front and rear does beep using the 4 front and 4 rear sensors only if I am not mistaken.
Also I don’t think there is something wrong with your system. The park assist modules need all components there to work. Even with one sensor faulty, the whole system stops working.

Yes, you are absolutely right. The system is working fine and I am very happy that I was able to retrofit the pla2.0 thanks to everything you wrote here.

I just want to ask as I haven't attached the rear two pla sensors yet and I wonder what the bracket should be? If anyone has put the extra two pla sensors on the rear bumper, can you tell me what brackets they used? Should they be the same as the front with a slope or something else?

 

[George Kost]

I only know @Troubs12 that has PLA 2.0.
Maybe he can tell you. Or somebody else.
If it was me, I would look the holders of the A4 B8 that has the 2.0.

Does your display on the dash stays the same for parallel parking and bay parking? Or does the rectangular shapes change?
I think that our dash cannot display the bay parking correctly.

My 8P is MY2012 and the dash display does not change. But that doesn't bother me. The only thing that annoys me is that I can't activate the OPS.
When I was reading the whole thread I noticed that you touched on whether the dash on the 8p is the same as the passat. Yes, I can claim that the dashboard of the facelift 8P is almost the same as the Passat B7. I have disassembled my dashboard to flash the eeprom memory. I have also disassembled a Passat b7 dashboard and I know they use the same display. So it might be possible to make a custom firmware that renders parking correctly.

 

[George Kost]

Keep us informed if you make any progress with the firmware!

Hi @henkkeumus, could you send the link to the complete guide you made for retrofitting the pdc and pla?

Quasi terminato il retrofit con 10 sensori, ecco la mia centralina abs:


Indirizzo 03: Freni ABS (-----) Etichette:. ITT\1K0-907-379-60EC1F.clb
N°. di Ricambio SW: 1K0 907 379 AD HW: 1K0 907 379 AD
Componente: ESP MK60EC1 H35 0104
Versione: 00H35001
Codifica: 11424012092200FB880C02E5901D00423800

è "vero" per il sistema pdc+pla? Qualcuno può aiutarmi? Grazie mille. My A3 is a facelift model, year 2009, 2000cc ambition.

 

[ilbruni]

I built and connected the front harness, with the 4 front sensors and the 2 pla sensors. I am sure that everything is connected correctly because the error I was seeing has now disappeared, and if I try to disconnect the individual sensors the vcds gives me an error precisely for the sensor that is not connected. So now I have everything connected, but the system still doesn't work. When I engage reverse gear, the drawing of the car appears for a moment on the RNS display (a 193G, coded to display OPS) but then disappears. And the LED on the button flashes. With the VCDS I read an error in control unit 10, due to lack of communication with the ABS control unit (error 01316). The park assist control unit is 8P0919475J, the ABS control unit is 1K0907379AD, the steering box is 1K0909144M (and I think it's a GEN2...). I also read "ESP component MK60EC1" but I'm afraid it can't communicate with ECU 10. And I don't know if . Can anyone help me? I'm afraid I'll have to change the steering box...

Hi can you check the coding of the parking aid unit (10) and repost? I’ve messaged you direct also incase you miss this. I’ve been crazy busy and haven’t had time to get online for ages. If I can help let me know

IIRC I used VW Touran rear brackets as they were smaller and kind of gauged the position by eye on one side then measured it for the other. I can post some pictures if it would help?

Ciao, puoi controllare la codifica dell'unità di assistenza al parcheggio (10) e ripubblicare? Ti ho inviato un messaggio diretto anche nel caso ti mancasse questo. Sono stato pazzamente occupato e non ho avuto il tempo di connettermi per anni. Se posso aiutarti fammi sapere

Qualcuno che sappia dirmi con certezza se per il Park Assist è necessaria la scatola sterzo GEN3? Nella mia auto ho una GEN2.

 

[ilbruni]

Nel frattempo, esistono le A3 8P con il 2.0

 

[George Kost]

In order to assist you if needed, you should be writing in English.

 

[ilbruni]

I’m sorry. I wrote in english, but automatic translator modified in italian. I'm not able to modify previous posts, so post again now:
my park assist doesn't work. With VCDS I write:

Error 01316 - ABS - 013 please read foults memory
I checked all the connections, all 8 sensors, the two buzzers and the 2 buttons. Everything is connected correctly.
The problem lies in the lack of communication with the ABS control unit. The ECU code is 1K0907379AD.
I have a GEN2 power steering ECU and not a GEN3, I hope this is also not a problem for the park assist.
Someone who has done the retrofit on the A3 with these units and/or who knows how to help me?
This time I wrote in English, I hope there are no automatic translations.

 

[Troubs12]

Mate I’m sorry I’ve been meaning to look at your abs coding but things have been crazy here at the minute I’ll try and get it done tomorrow.

Troubs12, it's all right!
I too have many problems, a family and a job and I have very little time left for the car, I perfectly understand that if you don't write it's because you don't have any news yet.
I always thank you anyway

Hello!
First of all big thanks for all the details about the lengths,the part numbers and coding. I started also this retrofit, but... i have a single error on the module and I don't know what to do anymore.
First of all my car is an a3 8p 5 door 2010
2.0 cbab manual Lhd without factory fitted parking aid

I did the loom for all 10 sensors from the beginning
Took the sensors from a donor car
The pla module is 8p0 919 475 E , so it's a PLA 1.0

I did the coding for gateway - installation list- checked parking aid 2- everything good

On steering assist - adaptation - installation park steer assist - 0 - everything good

On instruments - coding - added + 128 on coding - everything good

On the pla module the coding is 100003
And on the navigation i coded for optical parking aid

And it throws a error code only on the pla module
"1 Fault Found:
01316-ABS Control Module
013 Check DTC Memory"

The abs module is 1K0 907 379 AN
ESP MK60EC1 H45 0107
WSC 06314
And the coding for abs is 1142401209240000881302EC901D00423800

No errors on the abs, on steering assist, on navigation, on gateway, on instruments... only on the pla module.

The system works for 1 or 2 seconds..it shows on navi the OPS but after that a long beep and thats it... when i press the park assist button, on the dashboard shows "system not available"

The loom is good because i checked with another module ( 8k) not PLA and it works perfectly. But with this one it gives this error.

Here is a video how it shows on the rns-e


I hope that i gave all the details

If anyone can help with this please help

 

[ilbruni]

I have the same error. Unfortunately, also this system is “all things or nothing”, and so it works for a few seconds and stop. I tryed with 475J ecu (pla 1.0) and 475P (pla 1.5), always the same error. Now I have a 475D ecu and all thing works. Probably the problem is due to no communication from the abs ecu (my ecu is 1K0 907 379 AD). Did you try to see the last 2 bytes of abs ecu? I don’t remember, but propably there is a bit to activate.

I’m afraid… both of our abs ecu are “poor”…

 

[christiann]

The last bit is i think bit 17 and it's only tmps and another thing.. don't remember right now how it's called..but if i enable it...it throws the code " coding rejected out of range"...
I hope that is something else to do in coding the abs and it's not needed changing the abs module

Me too.

Hi, i have a question. I have made the wiring looms myself and was wodnering if i had used 0.5 mm2 wires for everything or if i mix and matched between 0.35mm2 and 0.5mm2. Would that affect anything? I know on the wiring diagram it shows specific size wires to use but i didnt realise until later after i have made the looms. Would i still be ok to use these looms i made?

I used 0,5mm for all looms and didn’t have any issues.
I am not electrician, but I suppose that it might be a problem if you used smaller diameter and probably for the power wires.

ok thats good. I used 0.5mm for my main looms but my parking sensor looms i bought some from ebay which were 0.35mm and i added the pla wires myself using 0.5mm wires and then i spliced into the 0.35mm wires. was wondering if it would affect the signal or anything?

Nah 0.35 will be fine it’s 0.50 for power and 0.35 for everything else but to be fair using 0.50 won’t hurt it

io ho comprato una centralina per 8 sensori…

 

[Igoaam]

Hi i need some help, ive install front and rear parking sensors. ive wired everything up and ive tried to code it but according to the pdf file i followed by @henkkeumus i need to activate APS by ticking ‘Parking Aid II’ but i did not see this option on the list only park assist and park/steer assist. So i turned these on hoping it would work and then i activated optical view theough park/steer assist module and navigation. But nothing works and im not sure what ive done wrong. Im sure ive made the looms properly. When i put it on reverse the pdc button lights and beeps loudly continuously and thats it. The sensors dont work and nothing comes on the rnse.

Does anyone know what im doing wrong or is there another way for me to code it. Is there anything i can check?

Also i just want to confirm on the pdc/pla module which loom goes where? I know where the T16f goes but which one goes in the middle T12t or T12i?

Any help would be appreciated. Thanks

 

[Igoaam]

I have checked my looms doing a continuity test and they are working fine. I soldered my wires on to the can gateway on pin 6 and 16. Ive added a wire to the fuse and i added a 5A fuse (im not sure which fuse to use for the parking sensors but i did try other ones). Ive secured my ground to one of the fuse box screws, sanded the paint off to expose the metal. I have the 8-Channel PDC + PLA 1.5 Module – 8P0919475K and my car is 09 plate a3 facelift model. The pdc button flashes and make a long loud beep noise when pressed. The pla button doesnt work or turn on when pressed.

But the error code says theres an open circuit on the can gateway and im not sure where. My parking sensors dont work.

Now my battery drains and im getting the following error codes

Getting a bit worried here and want to fix this asap. Any help would be appreciated sorry for tagging you guys but really need some help here. @George Kost @henkkeumus @Troubs12 @NHN Thanks

 

[MT-V6]

Do you have the CAN high and low the right way around?

283 modules use convenience CAN and 475 use powertrain CAN

Gateway 6 and 16 is powertrain. 6 is low, 16 is high.

6 goes to pin 15 on the 16 pin PDC connector. 16 goes to pin 6

Edit: just seen you have a 475 so check the above

Also regarding your coding question. 475 is module 10 park/steer assist. 283 is 76 park assist. Make sure you only have module 10 enabled in the installation list or they might conflict and cause issues

I did check my wiring with the multimeter and im sure ive got them the right way round. I will check again. Just to confirm the CAN gateway is behind the glovebox where there is a module? I spliced my wires in to the can wires. Should i try swapping the wires on the can and see if that helps?

Im not sure if i did try it without enabling 76 park assist but i will give that a go and see if it helps. Would enabling these teo together or the can wires wrong way round drain the battery?

 

[MT-V6]

I don't actually have an A3, I have a TT, so the wiring is the same but module locations differ. However on my TT it is behind the glovebox...

I'm not sure about the battery drain. If CAN is not putting the modules to sleep I suppose it would drain the battery. Not sure if incorrect wiring could cause that though

Are you able to see the module 10 on VCDS, and access it's coding etc?
