Afternoon folks,
So my new to me car has a couple of faults and preventative maintenance jobs that I'd like to get done. Starting from the top:
Vacuum Control- I've done a bit of research and it seems my vacuum control for brake boosting has failed. Bmw now provide the sucking jet pump and the hoses as a single assembled piece but the ejector part is now plastic and my original looks to be metal. Anybody used this new plastic pump? Also, is it possible with the DISA removed to change the whole thing or does the inlet manifold need to come off?
Talking of DISA's, I've seen some upgrade kits with the spindle screwing into the blade which I'd like to do. Have folks done this and whose kit did you use? Just trying to work out whose is the kit to go for.
My idle is a bit lumpy on start up so I suspect my icv may need a clean/replacement (although replacement looks expensive so cleaning would be better). Have people used carb cleaner or throttle cleaner on these (or maybe even just petrol)? I'd heard that carb cleaner leaves a lubricating residue whereas throttle cleaner doesn't? Not sure whether lubrication is required on the icv.
Lastly but certainly not least, vanos system. I'm feeling a little hesitance to rev around 2-4k sometimes so I wonder whether tha vanos is in need of a refurb. This would be a nice preventative maintenance job to do to release more fun factor
. Which kits have people used? I've seen a few on the Interweb but I have no idea which manufacturers/ suppliers are the ones to spend my hard earned £'s with.
Im not new to Z4's but I am new to maintaining them (my 1st Z4 was on a service plan) so any pointers to any of the above would much appreciated .
Muchos gracias!
