UK-POLOS.NET - THE VW Polo Forum

Hope everyone is good
MY polo is 2016 6c
There are only 2 window switches that control front seat (L & R)
I want to add the rear seat switch (L & R) to the driving position, how can I do this?

Hi, I think your POLO is a 6R.
For what you intend to do you should study the wiring diagrams, it is a very simple task if you are comfortable with wiring.
There are notable differences in the equipment depending on where the 6Rs were sold, so it is advisable to have the appropriate diagrams. 6R Taiwan 'vs' 6R Europe (for example).

Hi ciclo
Thanks for your advice.
Yes, I can be wiring myself. but I need someone to teach me step by step.
(just like BCM T73B/17 wire to T28a/16 ....because I'm not sure it's right.)

It is correct for the LIN of the front doors.

Do a search in the PDF for the Convenience System, there is everything you need.

This modification is not common in Europe, I don't know if there will be a step-by-step guide.

Ciclo
Thank you for your great support.
Now, I just need to add a LIN wire(to J386/387/388/389) and replace the J386 module right?
May I have your email? If I have any questions to ask.

Ask here everything you need to know, maybe another forum user or I can answer your questions. Everything I do here must be shared publicly.
I only share my email if it is something related to sales... for data protection, although my tendency is to sell little or nothing.

Obviously, I don't know if you have to change the WRM (J386) on the driver's door or just change the coding of the current one.
Autoscan?

I know the original BCM(J519) without LIN wires to the window switch, until I install a multifunction steering wheel

Can it be achieved by only changing WRM (E512) or changing the code? (Don't need to add LINE wires)

do you have a diagnostic tool like vcds to read the information from the control modules?

Yes, I have VCDS

could you make an autoscan and post it please? i'm curious to see what it is inside this car

Well, you probably already have the LINs on all WRMs (4 doors) due to your current operating unit for window regulator in driver door (E512) - with driver and passenger window switches, and 'rear window regulator isolation switch (E39)' -, so you probably only need to install the new switch (E512) and the missing wires to this new switch from the driver's WRM (image above - green box). It's just a guess.

Until you have 10 posts you can't post autoscans on the forum.
If you want you can use a server to host the Autoscan and post the link to it here, so we can see the ins and outs of your 6R and get a clearer idea of ​​all this.
I suppose your 6R model was manufactured as specifications for the Chinese market... it's definitely interesting.

I think it's not easy, because my driver's door switch only has 10 pins, and the rear seat switch only has 4 pins.

It is definitely more complex, that is why we asked for the Autoscan -more info-.

Due to the connectors you show, the technology/components applied for the 6R in Taiwan - supposedly for the Chinese market - is different from that applied for the 6R in the European market. We could say that the technology is somewhat older, which is not synonymous with worse.

As I suggested, you need to have the wiring diagrams for the 6R Taiwan model to compare with the 6R Europe model, so you can decide if this modification is possible.

Yes, I understand.
It seems that this type of car is only available in Taiwan.
But I only have VCDs, how can I Autoscan? Can you tell me how to do it or some operate roadmap?
Thank guys
