I think I need flash to 5Q1953507GF and upload dataset V03935426TC, that my guess. it is probably too complicated - finally I will try to find original GF and then only simple coding will be needed..

Is it mandatory replace the combination switch if my car has all of the other features?

Depends what you want to retrofit. If your car have hating wheel already installed for travel assist you don't need replace combination switch. Only steering wheel needed to be changed

Travel assist came as standard on mine and I love to use it, except when I got mistake of "temporary unavailability" but I know it's and old issue by Skoda and service will fix it!

My is from 2024, I never got this issue of "temporary unavailability" TA. I've been using this function more than 6 months travelling about 4000 km in Poland, Germany, Italy.

Finally I got new combination switch from O4 so I will try to code heating wheel, hopefully in that time without any problems. So in your case retrofit heated steering wheel require new combination switch.

If you want only heated steering wheel retrofit you still need to change everything like shown in the video or in the description

You don't need to change the whole combination switch , only the round control module unit Example here

but you still need the cable adapter for wiring plus and ground

And coding only Gateway 19 and Air conditioning 08

And i never had the message "temporary unavailability" when driving,only happend sometimes when only ignition is on

5q1593549 F should be disassembled from the same configuration with only difference of heated steering wheel. I have 5q1593549 F from Cupra and this generating problems due to different configuration setup inside this module. The subsystem is still identifying as Cupra combination switch 5Q1 953 507 GA in my Octavia, the correct HW should be 5Q1 953 507 GF (estate with heated steering wheel). The whole software of combination switch is stored inside 5q1593549. I checked this in two 5q1593549 F modules, both generating ACC problem and other errors because they are from different cars with different levers (eg Cupra have 2 levers O4 have 3 levers ). Good that I had possibility to return this parts and finally I got cornet one disassembled from 5Q1 953 507 GF. So be aware on that.

@wellaflex @mr25 : luckily I ordered the right one: https://ebay.us/m/YI1uTT

For what kind of car you are looking for 5q1593549 ? Here is the list of combination switches in your link , in my mind this will not fit for Octavia

Karoq 1.5 TSI

About TA problems

According ETKA Karoq 2023 heated StWheel combi switch 5Q1 953 521 LC. I still have one in my garage, maybe during the weekend I will connect to check what is the number in subsystem

Mine is 22

I think is the same generation - You should have right now 5Q1 953 521 LB. You can open top plastic cover on the steering column or logging to 09 central electring subsystem

Today I finally installed 5Q1593549F disassembled from 5Q1953507GF. After coding no any errors :) Everyting working. I also connected other 5Q1593549F to check from what combination switch was disassembled - it is showing 5Q1953507GB in subsystem. So I have 5Q1593549F suitable for Golf VIII. Itis from 2023y - if someone need, contact me on prv. This from Golf generating errors in Octavia due to different setup (ACC doesn't work) So that confirm that doing this retrofit 5Q1593549F must have suitable software inside. That is lesson learn for others - ask the seller from what car was disassembled.

Hello, i have NX 2023 only with standart cruise control and manual gearbox, so i dont need ACC, but i wnat to retrofit heated steering wheel and code TA it shoud be possible without capacitve stearing wheel.. Can somone help me with parts? I just dont know wich steering column i have to get ? I found 5Q1953549A, it shoud have heating but i dont know if it is the correct one for my car, than i need the cable (that from ali for 5q1 is good i thnik ? ) and steering wheel.

Coding for heated wheel is the same, and TA i found on obd11 forum and someone sad it works good without acc and capacitive wheel ?

Thanks guys for help

if not whatever... dont care about tahat much i will have not functioning button... , more i need heating, so if someone know what column to use and other parts, i will be greatful

Autoscan?

5Q1953549A probably fit if you have 2 levers in your combination switch. Check first what is your original configuration of whole combination switch. You can open top cover without disassembly steering wheel or read what is in your subsystem

This is in the car now

Most probably you need HW: 5Q1953549F Currently in your subsystem 6 - Part No SW: 5Q1 953 507 FN HW: 5Q1 953 549 D. I'm not sure about SW. SW is the same like whole combination switch. Read my case - I was ordered two 5Q1953549F which was not fit due to software inside. Finally I got proper one with both parameters matching my car. My ETKA account was expired so I can't looked in your VIN configuration. Maybe someone else have and make advice.

Anyone from EU willing to try retrofit Travel Assist without changing steering wheel?

I'm working on LIN adapter, that can be integrated, simulate KLR and activate TA from Assistance button. As well as fix Travel assist currently not available error

Yes I have the same, now have to codify it; any suggestion?
