Sorry. To make clear:
I have always had a mix of water AND screenwash (which also acts as
antifreeze) in BOTH tanks. I have only just found out that the second tank
is supposed t obe concentrate only (don't know why). As such, there is a mix
in the "water" tank, and now just the concentrate in the top tank.
Why is there a separate concentrate tank in these? Does it mix them? Or does
it just ALSO give a squirt from the concentrate every x amount of squirts?
Anyway, I have never had a problem with this before. And it wasn't even
telling me that it was low just before I ran out.
When I had run out, upon stopping the car it said "washer fluid low" (quite
rightly). It was only then, AFTER filling back up, that it STILL displayed
the message upon starting the car. I wonder if it has got some "crap" in the
water, and upobn running out has drawn the "crap" down into the pump and/or
sensor and gunged it up?
Only a thought. Didn't really want to start messing about taking things out,
but I want to get rid of the car soon and don't want all sorts of messages
popping up. So I suppose I am gonna have to take them out to investigate?
