    Has anyone rebuilt the WURs on a BBi? I found a company, T&S Engineering that sells a rebuild kit. It appears to be high quality and made in Germany.

    In my case (done a year ago) I disassembled, cleaned and adjusted, there is a lot of info about this here and on other forums (many cars like MB or VW had the same system). I think I only replaced the seal on the housing and an o ring, these are pretty solid devices. Things to look out for are: avoid scratching the metallic diaphragm, checking the screen filters on the fittings for debris and being careful not to damage the electric connections during disassembly. Some info I used http://b2resource.com/PDFs/wurfix.pdf.
    You will need the fuel pressure gauge kit to make adjustments (lots of install/remove) and do both wurs, since they are bridged the pressure will always be set by the one that is adjusted lower

    have a look at the WUR, there is a bosch number. with this number you may go to a bosch dealer and he may look in what cars this WUR ist inside. but when you not know a bosch dealer then you may get problems to find out. or have a look in the internet with this bosch number
