Screen wash leak

Postby Mountainman » Fri 16.04.2021, 16:12

Hi all

Please see the pics.
Basically I have major screen wash leak, looks like corrosion but cannot see if a pipe is split.

Guessing a costly trip to the garage, any ideas please? I’m under the impression this needs to work for MOT purposes.

Thanks
Jamie

The screenwash pipe runs inside the car on top of the tunnel.

For a leak there it is most likley that the connection to the non return valve (S2) or washer jets has come detached - they are on the inside of the bonnet.

Hi thanks for the reply and info.

I checked under the bonnet and all the connections are in place next to the jets so everything looks fine before the
Pipe vanished into the belly of the beast.

I will check the tunnel not got round to that yet.

When I refill the screenwash reservoir in the boot there is no sign of any leak
Until the i activate the screen wash pull lever then the tank empties itself like in the picture
From underneath the car next to the drivers side front tyre.

Another frustrating one tbh but will hopefully get to the bottom of it.
Thanks

Have someone look under the bonnet while you pull the lever.

Hi

Me and a friend looked under bonnet, screenwash defiantly not pumping that far.
Tbh at a loss now, would not even know where to start to take the tunnel apart to find pipe.

Fear garage bound.
Thanks

It is quite straightforward and definitely worth a go only a few screws. The instructions are in the manual and elsewhere on here.

The hardest part is sliding the leather gaiter over the handbrake lever and getting the whole thing past the gear knob.

:agree: I’ve had the tunnel cover off several times and it’s really not a big deal. As Simon says, the most fiddly part is easing the handbrake gaiter over the end of the handbrake lever. NB: if you want something that’s really a pain, just decide to replace the gaiter and then see how easy it is to undo the fixings :banghead:

I’m puzzled by your description of the symptoms though. If I remember correctly, on my S2 at least, the washer tube comes from the reservoir, along the tunnel and then through the firewall on the near side (UK passenger side) of the car to reach the non-return valve and then the jets under the bonnet. I can’t therefore see why you’d have a leak by the drivers side front tyre. :? There shouldn’t be any washer liquid in that area at all.

I wonder if perhaps the pipe has been damaged or pinched when a previous owner refitted the tunnel cover, causing a leak, and the liquid is seeping down to the drivers side floor and out through a drain hole. In which case you need to fix it promptly to avoid corrosion on the outriggers.

The screen wash tube does come in via the N/S so I suspect your latter diagnosis Jonathan. Jamie can you check if you have wet carpets.

Unless the tube to the O/S (driver side) sprayer nozzle has become detached under the bonnet ??? Can you check the spraying operation again whilst your mate looks under the bonnet for obvious leakage

Is there a possibility that a previous owner/repairer has been confronted with a blocked/squashed/split or otherwise defective pipe under the centre console, and took a simple method of 'repair' by simply running a new length of pipe between the tank (pump) and nozzles, and routed it under the car, or through the car against the drivers sill area????

Tunnel will come off! But could not do it today. Two screws no problem, the 3rd never in a million years, solid.
Obviously threaded and more drastic action required.

Checked the carpet and mats, wet through on driver’s side where the screenwash exits underneath the car, so no surprise there to be honest.

Will keep at it!

I would take the opportunity to remove all carpets and check the jacking points, outriggers/cills etc....whilst you are checking your screen wash problem. The carpets/mats will dry off better outside than in-situ anyway

I would be very surprised if there was no corrosion, particularly as someone has done a botched re-routing of the washer pipe in the past :? Should you need to do repairs there is plenty of information here..........viewtopic.php?f=30&t=17298

There is a drain hole in the cill but you'd have quite a lot of water before it came out of it.

Are the carpets easy enough to remove and put back? Never really
taken a deep look at that.

Hi all

Finally tackled the issue with my friend with a great result.

Took the tunnel off, took the drivers seat out (room to work)

Took the speaker out and removed all the carpets.

Sponges under carpet wet through. Dried out everything.
The screen wash tube was down the tunnel and
was disconnected to a pipe
Around the gear stick, not sure if this factory standard but joined them back
Together and made repairs so they should stay connected (hopefully)

Worked a treat! Screen was jets fully functional. Put everything back together.
I find just having that little bit of confidence to take things apart really helps
And undoubtedly saves £££ at the garage.

Thank you all for your help and input as always on this one!!
