I had posted this video a while ago about how to adjust CIS pressure and saw that it was really easy for this person to do it with his particular WUR on his car. I looked mine and I have this style though:
Now according to the Bosch part number and my style WUR having no vacuum connections, mine has the hole in the dead center of the backside of the WUR. The video shows he did drill a small hole in the backside thus revealing the allen screw for being allowed to adjust accordingly.
I have read up on doing a adjustable WUR, but from what I can gather for info is it only affects the vehicle on cold pressure, not warm
I would rather get the WUR like the particular one in the video because it'll make it a lot more easier to for me to make adjustments to warm pressure and I will do the cold pressure adjustable mod as well, but I don't know if there's a particular bosch WUR to get that'll fit my application or if they'll all fit just fine. It's a 16V on CIS-Basic if that helps. Thank you.
