Where to start with Vanos maintenance?
So no real issues, no codes, runs fine, etc. (other than a few seconds of rattle on warm startup) with my 2000 Vanos, but I'm curious if any preventive maintenance is considered wise. I'm quite sure I don't want to pull the whole Vanos units off and mess with the timing, etc., but I'm considering either the later accumulator w/shutoff upgrade and/or a refurbishment of the solenoids. As I understand it I can accomplish either of these without pulling the manifold, timing covers, radiator, etc., correct? I realize that with an 01/2000 build date I will need to both run the harness and program the DME in order to upgrade the accumulator though. So my options then:
1.) Don't worry about a little startup racket, wait until there's codes/running issues before touching anything.
2.) Go for the accumulator upgrade, as per the TIS it *should* fix the startup rattle, and after all rattles are generally a BAD thing.
3.) Solenoids are more important/integral parts than that useless accumulator, start with making sure they are happy first.
4.) If starting down this path, might as well bite the bullet and do both at one shot.
What are the prevailing opinions here? Thanks!
