As the title suggests. I can hear water bubbling (front work fine), but nothing on the rear windscreen or camera.

Any idea where the pump is? It looks to be buried in a right twat place under the headlight (Cupra 'never again' Born V2).

The pump is running, so I think the pipe is either damaged or blocked. Not sure how to fix that tbh

Dunno but rear jet dribbles whenever I use the front ones, a bit annoying.

This sounds broken.... like the water is going somewhere it shouldn't. You can hear a loud gurgling noise from the passenger corner of the interior.
Carpet doesn't seem wet or anything, but access is totally impossible to the pumps. Buried under a pile of headlight, bumper and other stuff.
Might try removing the pipe somewhere at the rear and blowing it through lightly with a compressor, but I suspect it's gonna be more than that.

Are you sure it's not just frozen?

I’d suggest it’s this. I mean it is cold out and water freezes. Even if you use anti freeze windscreen solution the nozzle will freeze over.

I’d suggest a visit to a Vw or Audi dealers and ask parts for their -25°c winter windscreen solution. I’d highly recommend it.

As a mechanical engineer..... no it's not frozen. Like I said, I can hear the water going somewhere. And the front ones work fine and they are coming from the same water bottle

You should have been a plumber so. :roll:

A hose has come loose.

Yea.. .I realise a hose is loose/broken/blocked. Or... the rear pump has failed. It might be running, but doesn't mean it's pumping.
Trouble is, the pipe to the rear isn't visible anywhere at all. Looks like the front bumper has to come off and the headlight.

I am going to take the rear windscreen jet off and fire some low pressure air down it with my compressor and see if the washer bottle 'bubbles'. I can then go from there.

Isn't it still under warranty? Get the dealer to fix it.
