Citroen C4 Picasso B78 Windscreen Washer Sensor

Unread post by steve551 »

Hi all

I have a Citroen C4 Picasso Aba-b7875g01 7ST 5DR Auto 2017

The service light comes on when I use the windscreen washer. I have filled it to make sure it was not low and the problem is still there.

I believe it is the windscreen washer fluid level sensor that is faulty and the car thinks the level is too low always regardless of the level.

Does anyone know how to access the windscreen washer level sensor and the part number for the windscreen washer sensor level? I would like to replace it.

Thanks

Stephen

This ad gives you an idea of what to look for, probably in the side of the washer bottle and it is for the Picasso II :)

Thanks again, appreciated. Is there a parts diagram available anywhere? I see parts diagram on some posts with exploded view and relevant part numbers. Not sure how to find that info.

Also wondering if anyone knows if this is a bumper off or can it be removed via arch lining?

Unfortunately the forum has currently not got access to the Stellantis parts database so we cannot find part numbers, however there are members with their own access and hopefully one of them will see your query and help out :)
