Personally I've always liked the hose to be extended up the wiper arm so the spray nozzle is always at the wiper blade through out it's travel.

The washers jets arrived today, hopefully the wiring connectors will arrive soon.

Tested them, both are around 50ohms, so just 0.25A each in a 12v circuit or about 3W.

I've got a 2015 XF and the washer jets are on the wiper arm, about half way up and it drives me bonkers! It also delivers a presumably eco friendly preset amount of screen wash too, which is never enough and so you just keep pressing it anyway!

The BIG downside of having them there is that the screenwash doesn't have enough time to travel along the wiper blade before it get's thrown off so the tops and the bottoms of the blade smear badly, especially on the bottom if you are driving along as simple physics dictate the water only travels up the wiper blade!

Give me 1990's tech washers any day of the week.

Good find that man!! +++

I've now received a couple of the Chinese heated fan spray heads, and they are quite loose when fitted. I have the spacers (thanks Ray) but for the life of me can not figure how they attach. Any pictures or help much appreciated. TIA

Well they have arrived but are a complete waste of time, because:
1. The connector is NOT the same as the D2; it looks similar but is significantly larger so does not fit.
2. The unit is more "low profile" then the D2 or Focus units, probably one reason why the Russians raised it so much to clear the wiper arms.
3. The jet squirts more upwards than the Focus, and does not appear to be adjustable. (ref Russians again)
4. The unit is smaller so does not clip into the D2 mounting slot. (ditto)

But regarding the Focus ones:
And one answer is that I also kept the washer/grommet that helped seal them tightly to the Focus bonnet.
The new ones didn't come with those, but moving them across makes the fitting into the D2 scuttle much more secure.

Just need some decent weather now to go out, connect and test them and if OK connect up the heating elements.

Following the slight digression into washer jets and pipework (which I added to :o ) in MJ's thread about Vera's S8 I thought I'd continue here as it's more relevant.

I bought a spare scuttle panel (*from our sponsors) a while ago (to fix a mounting/sealing problem, but didn't use it in the end) and it included the jets and some pipework.

Sadly the jets have had the wiring cut off (not by me!) so can only be used unheated, but they'll do as spares. Prompted by the descaling comments I dunked them into some fairly serious professional descaler I use, based on Phosphoric acid, minimally diluted and warm.

As you can see in this photo, taken some time after starting, they are bubbling away nicely. And still are as I type nearly an hour later!
I positioned the jets downward, input pipe upwards, so that as they bubble away there will be a constant flow.

I've not tried fitting them yet, I'm still looking carefully at the geometry, and it's confusing. :Confused:

I'm taking the angle of the mounting plates for the washer jets, with the scuttle panel correctly fitted (which mine wasn't, but now is) as a reference.
This appears to be pretty much parallel to, or very slightly inclined towards, the face of the windscreen.

The Focus jets come out pretty much parallel (maybe a degree or so above) their mounting plate. As they are more of a diffuse fan than two jets they will probably have less range.
Despite the description saying they are adjustable, they are NOT! :(

My current Audi jets are definitely angled down with respect to the reference plane, so hit the windscreen quite low down, but there is a reason for that:
I currently have non-OEM "aero" type wiper blades which sit slightly lower than the OEM metal articulated arms do, and my jets are aimed to pass below the arm and above the blade when the blade is "parked".

If I had OEM blades I would need to raise the jets somewhat, in fact on the drivers side quite a lot as the jets would initially hit the wind deflector. But would they then land on the windscreen or shoot over onto the roof?

It would be helpful if someone with OEM wiper arms and blades could check their setup, in particular:
1. What angle do the jets emerge compared to either the mounting plate or windscreen face?
2. Do the drivers side jets hit the deflector?
3. Do the jets land on the windscreen at low speeds and are they deflected higher at high speeds?

Resurrecting this thread somewhat after 2 years of hibernation...…
My S8 had been SORNed but I had to tax it to use it a couple of times and then realised that it's MOT is now due fairly soon too - the 6-month extension that isn't after all!
Checking it over the passenger side washer jet is pathetic and I don't want to give them any excuses to fail it.

In the end I dunked it for a couple of hours in NEAT descaler as used above and after that its' perfect. +++

Note for anyone who's thinking of doing the same, there's a fair bit of disassembly required to get the nozzle free enough to soak it:
1. Remove wiper blades and arms, remove cover panel over wiper motor.
2. Disconnect washer pipe and heated jet connectors under that cover near the motor.
3. Remove scuttle panel fixing bolts - one each end one in the centre - and lift off panel towards the front of the car. Note locating tongues on the body that fit into slots under the panel.
4. Rather than unclip all the wiring and piping to totally free the nozzle I just undid one cable tie to give some slack in the wiring and took the pipe off then pressed the catch and popped it out of the mounting slot. That freed it just enough to dangle it into a small vessel full of descaler, carefully balancing the panel so as not to knock it all over!

A quick test by connecting a spare length of pipe from near the washer motor directly to the descaled jet proved it was good. Reassembled and tested fine, didn't even need to realign the jets. :cool:

When I've got it through the MOT I'll return to the original challenge and try the alternative jets I have. +++
