Hi,
I have a kessy enabled golf 8, MY 2021, but I do not have keyless entry to the vehicle. My kessy module is 5WA959436B. I would like to retrofit the new door handles with the touch sensor, but I struggle to find any info/retrofit kits online. Did anybody try to retrofit the door handles with the touch sensor to share their experience?
To me it looks like just the door handles need to be replaced and wired to the kessy module, followed by some basic adaptations, as the antennas and kessy module are already installed from factory.

Hi!
I am almost done with this retrofit but it is quite complicated.
No, the antennas are not installed. You have to mount one under the car for each side and wire them to the kessy module.
The kessy module needs to be replaced either with revision C or J.
After this, you need to flash both B7 (kessy) and 09 (bcm) with MATCHING datasets. Then code. Otherwise it won’t work.

Hi kkpr3, could you tell where you ordered the parts. I see these aliexpress sets, but I dislike the design of the handles with that chrome strip... Did you opt for a new kessy ECU or can a second-hand unit be used (i.e does that module have component protection?) |

Hi, no CP removal necessary.
The Ali kit won't fit correctly. Even the connectors are different.
You must trim the connectors and swap the pins.
Or keep your stock handels and move the sensor inside along with the little wiring and add the pins in the stock connector (from the handle to the door).
I did everything on my own using the factory parts (took a lot of time but no spare parts around),also this way it was super cheap.
Still stuck with the coding though.

Ordered the Aliexpress kit. Will take some time to arrive. I hope to switch the sensor inserts from the Aliexpress handles to my handle housings without the dimple (I really dislike the chrome strip) Will see how that goes...

Hi kkpr3, I hope you sorted out the coding  I am still stuck in the retrofit phase and would appreciate your help. Could you share the wiring diagram for the kessy module? All the wiring diagrams available online (atleast the ones I found) only show wiring for the front doors, not the rear ones. Would you know where to pin the two wires for the sensors in the rear door handles? Also, what is your experience with accessing the kessy module? Did you remove the dash or did you find a way how to approach the module without extensive dissasembly? |

Yep. There are no Kessy read handles in the Golf, so they are not in the wiring diagrams.
You can have a look at the Octavia 4 which should have all 4 handles with keyless sensors or try to match the Passat B8
