Hey,

- Return steering wheel to neutral position
- Remove negative pole from battery and wait a few minutes
- Unplug airbag unit.
- Remove old steering wheel (M12 XZN tool required)
- Install new steering wheel (M12 XZN tool required) fix at 30nm + 90 degrees

You need to ride 500meters. Then turn off car. After that remove faults. Should be ok.

Yess just did that and works perfectly! Also with the module from ebay so no message anymore.
Next step heated steering wheel

@witek_77 do you know why my travel assist isn't blue while it's on? I have seen in video's that the lane turns blue. It stays gray for me.

 

[istoyanov]

For me looks the same.
PS: wipe the dust

 

[giuseppearmran.randone]

Yes !
the coding is this:

control unit 03 brakes ,

long coding you move to the bytes, drawing 0101010101
you go to the bottom moving all the way to the right, count 6 going back to the left and you find an entry starting with A, mine was A2
Remove bit 01 and put in bit 02 - the entry becomes A4 .
Scroll to activate.
finished

the byte with the letter “A” followed by the number is in position 15 for me; can you confirm it is byte 15?

Su quale byte devo spostarmi e quale bit devo modificare per attivare il menu TCS, ESP ecc.?

Cupra formentor

Cupra formentor

Exactly as @simoammi said:

control unit 03 brakes ,

you go to the bottom moving all the way to the right, count 6 going back to the left and you find an entry starting with A, mine was A2
Remove bit 01 and put in bit 02 - the entry becomes A4 .
Scroll to activate.
finished

Now my A4 is on byte 26. I dont remember on which was A2 earlier.

 

[giuseppearmran.randone]

I hadn't noticed that it's already standard on mine

Lo más importante, ¿puede un volante con paletas para un coche manual? Quiero hacer esto para tener ayuda de viaje en mi sillón. Y la segunda pregunta. ¿vale la pena?

la referencia es 5FA959542

The seller tells me that he believes it is capacitive. But I would like to know your opinion, because it is not fr, it is x, and I don't know about the subject. thank you

 

[witek_77]

Hmmm. I have xcelence capacitive 5FA419091EL. but yours also looks capacitive. has a cable and plugs for the KLR module.

 

[ivanloenmk4]

thank you. My car is a manual transmission. Can I still mount this steering wheel and have it work correctly?

 

[witek_77]

thank you. My car is a manual transmission. Can I still mount this steering wheel and have it work correctly?

No. You need automatic DSG gearbox for Travel Assist

 

[ivanloenmk4]

Here I saw that it has a manual gearbox (in the cockpit you can see that it is in gear 6) and it has a capacitive steering wheel with paddles

Hello, I have a question, I have a Seat Leon 2023 with Lane assist, classic regulator and anti-collision front sensor. I coded the semblance of travel aid and it works very well. I have a Travel assist icon in my multimedia screen with the possibility of a Low-medium-eleve rule. But it is still active, I don't have buttons to disable it, I only have the button to disable the classic Lane assist. So to deactivate the "Travel assist" I must deactivate the Lane assist. I wanted to know if it was possible to have a button only to disable travel assistance and leave the classic Lane assist? Also, without a capacitive steering wheel it is still not possible to deactivate the message to get back behind the wheel?
Finally, with my configuration is it possible to activate the ACC? Thank you very much for your answers!

 

[Leon xLux st etsi]

Congratulations on your modification !

could you give us the link to the seller of the steering wheel ?
I can’t seem to find one on eBay or maybe I’m using wrong terms for my search.

Fantastic discovery, I have done similar think to my last leon mk3.5 and fitted cupra steering with paddle shifters.
Is there any acces codes needed to do coding? Thanks in advance

 

[Pierrecapo57]

mounted. Unfortunately, the percentages do not allow me to take the test today. the errors were cleared and nothing came back. We'll see.

@simoammi for me this module works perfectly. Yesterday I drove 30 km without touching the steering wheel. there were 4 red traffic lights and some traffic jam. the rest of the way about 90 km/h.

Hi! Do you think it will work for my car? I have a Léon 2023 without a capacitive steering wheel, I only have the Lane assist. Will it prevent me from haing the alert every 10 seconds? Thank you!

No you really need to have the capacitive steering wheel
