Are you sure it does not fit? It looks as it should to me
Yes sorry the photos Are Not the beste. The grooves from the Plug Are Not on the socket of the clock spring so it dont fit. Maybe These Photos Are a Bit better

Please dont Tell me I got the wrong Airbag just vecause I wanted the Cupra Logo 🤦🏽🥲
It's from Terramar and it works with 1EE953507 clock spring, not 5Q0/5Q1 ones. I guess that the airbag loom can be replaced or even adjusted by changing yellow connector and possibly switching some cables, but it's always a gamble.

If you want P&P solution then you should buy Ateca/Formentor/Leon KL airbag. For steering wheel with VZ buttons the easiest one to find is 5FA880201AR, but 5FF880201C and 5FF880201F will work too. For other steering wheels (without those two additional buttons) you should look for 5FA880201Q, 5FF880201B or 5FF880201E if you want Cupra logo.

Do you have the 6 pin black connector?

Hi, just to add. I see you have the airbag wiring for a steering wheel with start stop and mode button wiring. The airbag plug for this cable set is different in comparison with a normal 5q1 cable set. Just some pictures below of the clock springs (both 5q1) and the different connections.

Ooooh, that's a new thing to me! Thanks for pointing that out

edit. Just to confirm few things - airbag looms are not interchangeable. Here is a close-up photo of "standard" airbag loom connector and "G" clock spring. Without filling those side "tabs" it will not fit

edit 2. it looks like 4H0972208F (available on Aliexpress or as a part of Audi A4/A5 loom) might fit

Hello want to change seat leon mk4 kl diesel steering wheel control module from one without heating to another one with heating.
I bought one of those after market pre wired kits from ebay (you can see the photo) but the control module doesnt have an available connection for the wires, positive and negative.
I serched for 12v connection on the wired pins and i've found one but it only takes 0.03A and resistence consumes around 2.7/3A, and im afraid that the wire and connection doenst support it.
So Im now looking for a steering wheel control module p/n that has this pre wired connections for the heated steering wheel.
The one that the car has equiped is attached.
Can anyone help?
Thank you in advance

5Q1953549F would work for your car and have pinout for heating. It is not 12V pass-through though and voltage is regulated by the car (I don't know whether it is by BCM or slip ring itself). I would suggest installing steering wheel with preinstalled heating pads (with correct resistance, ~1.5 ohm) and heat activation button.

Hello, thank you for answering.
Since I'm using this cheap aftermarket solution, I hadn't planned on replacing the steering wheel. I was just thinking of using the wiring that's already integrated inside the wheel to connect the 12V, for example to a cigarette lighter socket and a ground. Not to the Climatronic controller, avoiding any reprogramming.
Do you think it's possible
