I think I may have posted this query before but I still have't got to
the bottom of this yet so I'll try again. I have a 1988 320i tourer
that under the bonnet has two washer bottles side by side, one large
that says 'water' and one small that says 'concentrate'. When I fill
the larger of the two bottles up and use the windscreen washers the
small bottle fills up with the fluid and eventually starts to
overflow.The two bottles have pumps on them which I have tried
swapping over but to no avail. I have re-tube the system with new pipe
thinking that there may be a blockage somewhere.. to no avail. I was
posted a link to a site that had a diagram for this system showing all
the pipes but this did'nt help as it was correct anyway. Does anyone
else have a 320 with this arrangment of two bottles and if so do they
have any bother like mine? P.S. There is a seperate washer bottle for
the rear wash/wipe at the rear of the car.
