Well did the washer jet mod on my CDTI 150 and it was pretty simple did not even need to take skuttle panel off just popped old jets down unplug from tube and bang the new ones in reverse also the guys in my local VX dealer told me if i needed them adjusted they would lend me the tool to adjust them which i had to take them up on.

These new jets are much better no waste and better spread really rate them.. Cheers to the guys that worked out these fit..
