    Thanks for the thoughts and experience.
    I’ve looked at the tanks on eBay, most do seem pretty grim on the inside.
    Will attempt to clean the tank when it is off the car, get as much out as I can before replacing the strainer. Worth a try for £8.

    I can see why the filter can get clogged up easily, the gauze is pretty fine.
    If it stops raining I will try to get the tank out and clean it then fit the new part.

    Interesting reading on other forums, folk using Steradent tablets to clean the gloop, syphoning the fluid out etc. Think I will go old school and take it out.

    The old school way is a good approach

    Old school job done. Working washers again! Hurrah.

    The old filter was totally blocked, amazed anything got through at all. Replaced with the new part and then cleaned the headlight washer filter.
    Cleaned the bottle as best I could, some Flash in there helped.

    Cleaned the drainage hole out as well, was full of leaves and muck.

    I’m answer to my original question, the sensor is definitely there. And it works, I must have missed the warning bong some time ago.

    Glad I did the job yesterday, the spray and grime on the M42/40 was horrendous today. The joys of working windscreen washers!

    Was there a lot of black slime in the tank ?.

    Not as much as I was expecting, some collected at the bottom of the tank, about the size of a grape. A film of grey/black on the internal surface/side as well. Gave it a soak with Flash floor cleaner in there, left to soak, then shook and rinsed. Still some left on the side but not too bad. Clean at the bottom where the pump is, for now.
    Will take advice and stick to one type of fluid.

    Walking back to the car in a multi story car park this morning, pink fluid all around the car in puddles. Buggar. Coming from the washer bottle, must be a leak/dodgy connection.
    Looks like I will be taking the wheel and arch off again!

    Seems to have been coming from this joint:

    The blue clip doesn’t seem too clever, possibly need to replace. Have put it all back together, will keep and eye on it.

    If it proves to be the source of your leak and it's not very slack, a couple of turns of PTFE tape [as used by plumbers] might seal it and save you having to resort to buying replacement part(s). :sneaky:

    A good shout indeed, bizarrely the good lady Mrs W suggested the very same thing this afternoon.
    Not sure how it’s coming out when the pump is off, that’s the feed from the pump to the headlight washers. Would assume that the water pressure with no ignition would be zilch.
    See how it fairs over the next few days. I shall be a whizz at removing the inner arches at this rate.

    The clip only really locks it on, the seal is in the hose so I’d be checking that as the issue, could it have fallen out or got pinched when you had the bottle off?

    The clip and pipe had to come off when the bottle was removed, possibly damaged the seal when refitting.
    It wouldn’t be too much of a pain if it wasn’t in such and awkward position.

    Obviously a bit late now but you can just get the pump out and leave it on the pipe and even the plug. If the seal is damaged it seems you can get the end to put on the hose but guessing its probably a bit of a pain, would need a bit of warming up with a heat gun or hair dryer to soften the plastic.

    So far so good since refitting the connector. I’ve monitored the bottom of the wheel arch to check for leaks and all clear. Hope it stays that way.
    Seemed odd to have just started leaking out of the blue, or pink in the case if the fluid.... Was weeks after I’d replaced the filter.

    had you used the headlight wash in that time? Sometimes it doesn't leak until the wash is used then it siphons out, usually that more the headlamp wash telescopes when they leak though.

    I was worried the headlight washers would draw the leak out again, but have used a few times.

    Fingers crossed seems to have cured the leak issue now. Nothing has dropped out since the last fix.
    Bought several bottles of the same washer concentrate, just to be on the safe side!
