After the recent cold weather when nothing was working washer wise, the rear washer is still not working now things have warmed up, although I can hear the pump trying.
The front washers are working fine, albeit the washer tank did require filling this morning, but I’m starting to think that I might have a split or blocked pipe now after the cold weather 🥴.

Note that the rear camera washer is not working either.
Any ideas??

Was it still not working after you filled the washer tank? I've previously had cars which would stop the supply to the rear wash system when the tank was low (dash warning light) so as to prioritise the (more important) front. Can't remember if the Macan does this.

Still not working after refilling, so will try and see if the jets are blocked perhaps.

Have you given it a good long run of the pump to purge any air out of the line? Could take a while as it’s quite a long run from the pump to the rear nozzle.

There's a possibility that if it froze and split the pipe you can be just pumping fluid into a cavity.

I have tried 5 second bursts but nothing more, perhaps I should try longer ??

The camera wash is still not working either, but I can hear the pump working. It’s starting to sound like a split pipe isn’t it 🥴

Pipe shouldn’t have split if you had the correct fluid concentration in the tank for winter weather. I’d give it at least a 30 second continuous run, maybe getting someone to operate the washer while you look at the nozzles. See if there’s any sign of fluid and bubbles suggesting an air mix that needs purging.

Presumably the main feed pipe from the tank will need to split off into some kind of Y connector at some point for camera and rear screen? Could this have simply come loose?
Would still mean fluid being pumped into a cavity behind the rear tailgate panel but might be easier to check…

Okay, so I went out earlier and tried a couple of one minute bursts and nothing, except for the car telling me to refill the washer bottle. Which sadly means that a whole tank of fluid has gone somewhere and there’s no sign in the boot or underneath the car.
Then I check the carpets - it’s wet behind the passenger seat ffs !!!!
