Windscreen washer fluid low warning.
#1
Windscreen washer fluid low warning.
Several other sections report fixes for the washer fluid level sensor.
I ran out of fluid with no warning and there's nothing in JTIS about a sensor in the washer fluid tank.
Before pulling off the wheel arch liner to investigate - do we have a sensor?

While JTIS gives no instructions for its removal/replacement, it does mention the Low Level Warning in 501-16 in the Body and Paint/Wipers and Washers section when describing the Powerwash system.
It is also shown in Electrical Diagram 14.1 as part of the Windshield Wash Pump assembly (Solid - not dotted - black rectangle.)
Looks like you've got one and it doesn't work!

Hi Steve,
Just looked at my wiring diagrams and it appears the windshield wash pump and fluid level sensor share the same plug from the BPM.
LF1-15 Y to LF27-3 fluid level, LF1-16 YG to LF27-2 wash pump, LF27-1 to LFS B ground.
From the drawings there is no sensor in the bottle so it must be part of the pump assembly.
Hope this helps.

As usual the answer is obvious.
'Jaguar Service' in the UK simply filled the washer bottle (capacity 7L) up with water.
We've had -10°C with daytime temps of -5° for a couple of weeks so an iceberg formed in the reservoir.
This presumably froze pumps + sensor.
When I topped off with -15° fluid I could only get 4.5 L in the system but the iceberg has melted and all, I suspect, is well.
The pumps still work thankfully.

Maybe that's also why Brutal finds pond scum in the reservoirs when the system gets clogged up.

I noticed in my early days of Jaguar ownership, when the car was still under manufacturer's warranty and I had the servicing done by my local dealer, that the washer bottle was always itemised on the invoice as having been emptied and refilled - not just topped up! Seemed excessive at the time but maybe not!

I find the headlamp washer system to be a waste of washer fluid. I presume I could pull a fuse to disable them during our ownership period. But the question remains: Would they then proceed to seize up and die as the fuel pumps seem to do during long periods of inactivity?
The Windscreen Washer Pump (item 5) is Fuse #7 (15 amp) in the Driver's side fuse box. The separate Powerwash pump (item 8) is Fuse #7 in the engine compartment fusebox (LH).
You could therefore pull the fuse for the Powerwash but I agree it's likely to seize up with lack of use because washer fluid seems to develop a slime after a period of standing.
