Retrofit and activate Formentor Windshield Washer Fluid Warning Light

[spezwend]

Thanks to @witek_77 for the information: https://www.seatcupra.net/forums/threads/retrofit-washer-fluid-level-indicator.474960/post-5049770

What you need:
1. Plug 1J0973202 for washer fluid level sender (G33 on the diagram)
2. 2x 2 meters of 0,3...0,5mm2 wire
3. Tesa automotive PET cloth tape (51007)
4. One MQS female pin for T46B plug (for pin 28, pin 19 just attach to the wire already there)
5. Something for coding (obd11, Odis etc)
6. Tank already have built-in fluid level sensor.

You need to disconnect and take out the battery, remove the left front wheel, unscrew the front part of the wheel arch, unscrew the plastic under the steering wheel. Remove the middle plug (B) from the BCM (T46b), unplug it, connect the wires to pins 19 and 28, pull it through the rubber seal on engine firewall to the engine compartment, lead it somehow to the washer tank (I led it through the top and went down behind the lamp just like the original washer harness), and connect the plug.

Coding:
1. 09 central electrics (SFD locked)
2. Adaptations
3. [VO]_HW_verbau
4. insufficient washer fluid > change from "not installed" to "installed"

Brilliant work

But why could CUPRA have already done this when access was easy, is beyond my comprehension.

Thanks. They do not need washer fluid in Spain, be thankful you get the washer fluid reservoir.

What MY is your Formentor? I'm curious if MY2024 ones have the reservoir with sensor included.

 

[spezwend]

Pre face lift models have reservoir with sensor but no wire and no plug. About the ugly face lift model I do not know.

How is possible?
Without

Washer Fluid Warning Light on NEW car ???!!!​

Thanks! Well, afaik the prefacelift model I have is MY2024. The dealer told me that the cabling and connector have been removed since MY2022.

Is this plug/cable missing from ALL Formentor’s or just certain markets/countries? (I’m in the UK) If so, this is cost cutting to the extreme, as I assumed it was already fitted

 

[spezwend]

This is missing from all Formentors. Don't know about the facelift model yet... actually don't even care, never gonna buy it.

Thanks for the quick reply and info.
Still can’t believe they decided to no longer fit this cable, crazy cost cutting…
Your not a fan of the facelift model then

You do not need washer fluid in Spain I guess. Crazy of course, what's next, no low-fuel warning or a gauge at all?

I do not like the facelift model, It's like cheap Chinese EV. But new lights are okay.

Hello! I want to do the same in my Leon, but before I start, I would like to ask you to help me with one thing that's not clear for me: where is located plug T46b, behind the fuse box? Thanks in advance. Robert

It's on the left side of the Body Control Module or fuse box, down from the A-pillar.

Thank you a lot for your answer. I've found it.
