TBH, first time I've had to fill up with screenwash since I bought it from VW in May 09!!
In December 09, I just put water in (in other words, a flush).
Then during this cr@ppy freezing weather, I put in a full bottle of this "miracle" liquid
and in a week, clogged up.
Just soaked them in hot water for an hour tonight, blew out all the sh1t, and re-installed. Sorted.
Now I've got a wash bottle 75% water & 25% VW screenwash. As this runs down, I'll be down to Halfords.
I accept the whole warranty issue thing, but I'm not going to go through the grief of booking the car in JUST to have the washer jets unclogged!
IMHO, it's just a bad design - probably one of the very few corners cut on the mk5....
