Hello at my 850 half a year ago I converted to V70 fan nozzles. 2x nozzles changed. Then it ran great until 2 weeks ago. After that it was only bluberting out of the nozzles. Tubes examined and found out that the distributor valve for the headlight wipers is over and the whole pressure dor is lost. Then at Scandix the 2 distribution valves bought for the headlight wipers and also for the windscreen wipers. This http://www.skandix.de/a/1006978/ and this http://www.skandix.de/a/1004048/ Now water from the nozzles again ABER the power broke in half. For that comes out super much from the headlight nozzles. There is even a huge beam of both headlight wipers. Yesterday I also at the 850 TDI from the Schwager the same action is done: 2x nozzles, 2x valves (profilaktisch so to speak). The same phenomen as regards the pressure. I had not read about the reconditioning?
