Parking Sensors
Parking Sensors
Hi guys, how's it going? I'm reaching out to ask for your help. I'm trying to install reverse sensors on my Polo — it's a 6R from 2013. I have this serial number on the BCM — (6R0937087M BCM PQ25). I'm planning to install this kit I found on AliExpress:
https://es.aliexpress.com/item/10050028 ... el=twinner
My question is: does anyone know or have diagrams showing where I should connect the wires or how everything should be set up? The seller sent me this (info), but honestly, I don't really understand it.

Re: Parking Sensors
Just an honest question, if you don't understand this information (that is pretty clear and correct), should you do the retrofit yourself? Do you feel confident enough?

Re: Parking Sensors
Maybe He doesn't know where the plugs are located. I think if he had that, he could pull it off by him self.
Re: Parking Sensors
Hello. After you helped me with trip computer, cruise control retrofit and after I did the remote control retrofit and bcm retrofit myself I will try with this retrofit ops 8k senzors.iichel wrote: Sat Apr 05, 2025 8:45 am Just an honest question, if you don't understand this information (that is pretty clear and correct), should you do the retrofit yourself?

My question. I neard on a forum here that there is a another module pdc which will auto detect for front senzors. Is it the number 5q0 919249A?

Re: Parking Sensors
Yes, you can use a 5Q0 module with 1K8 firmware on it to have autodetect.
Re: Parking Sensors
It sells for golf 7. So it will work anyway? If so, great. Do I need parking switch if I use autodetect? Also what do you recomend? Are chinese aftermarket full retrofit ok quality? I was thinking to buy used original pdc module and senzors, and wiring loom already done but new? Is that ok?iichel wrote: Mon Aug 25, 2025 8:33 am Yes, you can use a 5Q0 module with 1K8 firmware on it to have autodetect.

Re: Parking Sensors
yes the golf 7 has the 5Q0 module but with 5Q0 software. you'll need to write 1K8 software to it for use in PQ cars. still needs a button.
Re: Parking Sensors
Write softwear? That is out of my expertize. Is there any other module number to do the same? Without writing softwear?iichel wrote: Mon Aug 25, 2025 10:11 am yes the golf 7 has the 5Q0 module but with 5Q0 software. you'll need to write 1K8 software to it for use in PQ cars. still needs a button.

Re: Parking Sensors
Updating/Modifying/Writing new software is done by flashing the unit, usually with VAS-ODIS, VCP, or other less common diagnostic tools.
You must also have the appropriate flash files to perform this task.
Or, if you don't have the appropriate diagnostic tools, you can purchase the PDC unit already modified for PQ (6R = PQ25).
It's also worth mentioning that a wiring harness adapter is available to convert the electrical installation from a PQ25 PDC unit with three connectors to a modified MQB PDC unit with two connectors.
IMHO, it's best to do the electrical installation for PQ (OEM method) and then use the MQB->PQ adapter if necessary.
The only thing the 1K8 modified unit achieves is automatic activation of the front PDC sensors, and if you have a CM/DM rad/nav, the automatic OPS display on the screen. This is not the case with other radios/navigators (RNS/RCD 510, 310/311, etc.).
The 8K 7E0 units work well in the 6R (any of them). The 7E0 AA software is recommended, as it is the latest software available.

Thanks. So to conclude.
1. If I buy 5Q modified for PQ I also must buy an adapter mqb to pq? I did not know that. Also I now have android radio unit made for VW models polo 6r -canbus decoder (chinese), before that I had vw 210 model. It would not work for automatic front senzors also? (Cm/dm rad what that means?)
2. I think I will stay with an option with out automatic front senzors. So for that option I must buy 7E0 pdc modul for 8K and the use of any adapters is not needed? I bout wiring from aliexpress but senzors, brackets, pdc modull will be original vw, but used.

Re: Parking Sensors
CM = Composition Media
DM = Discover Media
DP = Discover Pro
These are the radios or navigators (infotainment systems) used in VWs that replace the older RNS, RCD, etc.
Newer infotainment systems also include new models/evolutions. MIB2/2.5/3 ...
I don't know what works on any non-OEM radio with CAN decoders (RCD 330/40, etc.?). I assume the OPS system will work.
However, the important thing is the beeps from the PDC system, the rest (on-screen displays - OPS, RVC Low/High, Area View 360º -) are small aids for people who have a lot of time to park in civilized places where the remaining traffic waits patiently for you to park after pressing a million buttons or viewing the parking lot on your wonderful screen...

Re: Parking Sensors
Yes, option 2 is suitable. OEM installation for 8K (8 PDC sensors with 7E0 unit).
