2008 4.2 NA. As stated, the washer motor seems to work, but perhaps the filter or hoses are blocked. I found this link: How to: fixing your non-functioning windscreen washer | Jaguar Forum (jaginfo.org) but it's for an earlier car and was wondering if this is accurate for later cars or... Thanks!

 

I can tell you exactly what the issue is - I fixed that exact same issue on our S-Type about 2 weeks ago.
I took heaps of pictures, but it's about midnight here now and I can't stay up longer to write the whole new thread now.
But I'll post that new DIY guide soon.
In a nutshell: The reason is all the crap floating around in the reservoir.
The rubber-filter insert is blocked and the pump cannot suck water out of the reservoir.
I dove into the internet and looked for answers of how to remove the reservoir, to clean it our properly, but all I found were stupid remarks, of how difficult is is and therefore cannot be done.
Spoiler: It is not easy, but it can be removed totally. Then cleanout is a lengthy procedure with a water pressure cleaner.

 

Thanks Peter -- holding my breath!

 

OK, Scrannel, you can breath again:

Thanks for this incredible tome. Right, one hell of a mess. But wondering two things:

1) Is it possible to suck the crappy fluid out from above AND get the muck blocking the filter -- or is it too embedded?

2) I notice these reservoirs with pump etc. are avail online -- is it easier to pull the old one out and put in a new one?

Thanks again for this amazing break down!

 

> Thanks for this incredible tome.

Thanks, Scrannel. And I just learned a new word: "tome" - I looked it up, it means a "scholarly book:.
...and I thought initially that you accidentally forgot the gap between "to me", and this did not make much sense...

1.) a.) It took me ages of treating the reservoir with the water pressure cleaner again and again, always purging the crap out in-between again and again, then brushing it again and again and cleaning it out again, There was so much crap in there, that I do not see it as a feasible solution to attempt sucking it out from the top in situ. Even if you do have a vacuum cleaner, which is able to suck water.

1.b.) As I described in my linked thread above, the rubber filter is an integral part with the rubber seal (one and the same part), in which the pump sits. And if you look at the picture, which shows the removed complete reservoir with its long neck, you will see that the pump (i.e. the rubber filter, too) are at the furthest possible distance from the long neck (the pump would be, where you see the hole), so cleaning that filter from the top is also not feasible. Just as it is not possible to remove the filter without removing the reservoir, as you have to remove the pump first, and with the reservoir in situ you can neither access the pump nor the filter.

2.) I did not check, what is available online, because neither my reservoir nor my pump were broken - there was just a lot of smudge in the reservoir, which needed removing, and I did that by removing the reservoir and cleaning it. If you buy a new reservoir or pump to replace the non-damaged OE parts, you would have gained nothing, as you would still have to remove and reinstall the reservoir and tank - in fact you would have made thing a lot more complicated for yourself, as this would require attaching the old hose to the new pump - and that is another problem, which I avoided having to tackle.

 

As another option. I had the same trouble. The cheap blue fluid gummed up my filter and pump. I took the bumper cover off and had total access to everything. 06 s type r. Should be same setup as yours. The cover looks daunting but is way easier than it looks. Peter has a great write up and knows his business. Just putting out another option. You also get a look at things under the cover you would never think of

 

> You also get a look at things under the cover you would never think of

Oh yes, the things you find when you go looking/hunting:
When I removed the shocks, initially aiming at replacing the rear lower bushes on my X308, but then I went on to replace the seals of the diff:
Removing the shocks opened up access to a cavity, where you would not have access to normally - and there I found a huge dead dried up rat - a rat-mummy...
So, I had some kind of mobile pet-cemetery...

 

i shudder to think what the possibilities are if all the bottom covers were removed

 

Speaking of Rats... I'm about to double check that one of our Blond Malibu Surf Rats didn't lunch on my hoses. When it dried out here, I finally noticed water dripping from the engine-ish area. Will report back!

 

Wanted to close this out: it was indeed RATS! Have replaced the squirter lines and trapped some rats. Time will tell how many rats I'm going to have to go through.
