Let the dealer send you the harness, you can have it modified at your end. The blocking diode is an addition in this harness but it can be sourced from your neighbourhood electronic components store. I have already mentioned it in the thread if you didn't notice:

The Aliexpress cables may not have this diode - please check prior to installation! These diodes are available at your neighbour electronic component shops and retail for Rs. 1 a piece.
You will already have the harness from the T41 connector (stalks) to the T32 connector (cluster) in place.

@Gannu_1
Do you know if it's possible to do a cruise control retrofit on a Polo 1.6 petrol?
I've got the same BCM as you.

It is doable for any Polo irrespective of the engine specs. Just that the BCM should be compatible. Its been ages since I accessed ELSAWIN. Let me check the relevant current flow diagram.

In the meantime, can you access the ECU's connector and share a pic? Take all the time you want and do it.

Haven't had the time to take pics of my car but found some on the forum.

Hope this is good enough.

Pin no. 24 of the ECU.

For those wary about doing this as a DIY, someone suggested contacting a Bosch service center. I see one in Bangalore at Banerghatta Road, called SK Karzone.

Any idea if they are knowledgeable about doing ECU work?

I was considering asking them if they can fit such an after-market cruise control kit for my 2011 SX4.

Thoughts?

Hi gannu!

I had been researching on retrofitting a cruise control on my Jetta Comfortline Mk6 for quite some time when I stumbled upon your thread. I have gone through your DIY for retrofitting cruise control in your Polo and it has been documented really well! Do you have any information on the Jetta too? It would be great if you could help me out.

Smile Re: VW Polo DIY: Cruise Control!

Hi Gannu Bhai,

Installed cruise control on my vw polo 1.5 Tdi and works perfectly.
First of all thanks to you for all the information that you had provided in this thread. Installed this at vw chandigarh as they had ordered the part no. 6R0953507B9B9 for the vw polo. Cost was 11000 Rs. Secondly the technician was of immense help.

Few things that I have made a note:
  • For powering the cruise control the wire from the T41-pin 28 to Fusebox 11 is already used by a fuse. For solving that problem I got hold of fuse tap connectors. But the technician came up with a better solution. The Fusebox slot no. 10 is empty. Thus installed a new pin there ( he gave it to me for free ).
  • There is a minor difference in the pin used for T41 connector and the pin used in the ECU connector. I discussed with the technician and then he took a pin from an old ecu connector and clearly the one used in the ecu connector was little thin.

Once again thanks to people like Gannu who inspire folks like me to attempt something like this.

Reviving the old question posted by "carizam".

I recently picked up a pre-worshipped Jetta 1.4TSi CL. Does the BCM on my Jetta support cruise control and it is just a matter of adding the stalk controls?
