Cleaning the injectors won't help that 99999 out of 100000 times.
BUT, the secondary injectors are the ones that are easiest to get to if i'm not mistaken... shouldn't be too much trouble to get out, just don't go and turn the fuel pump on or anything while the injectors are out

Pull the intercooler, upper intake manifold, all the vacume lines, throttle body water lines, OMP rod connection at the TB, disconnect the BAC, and then remove the secondary fuel rail via 2 12mm bolts. Just unplug the injectors and call it good.
PLEASE de pressurize the fuel system before you yank the injectors.
Did you try running a ground from the injector block ground to the battery?

Just a note, if you're going to send your injectors out to be cleaned, that means your car will be down for the week and half or so it takes for the round trip... Why not send ALL of you injectors, instead of having to take the car down for another week and a half later?

ok, i've messed up with that bolt *urgh*
now i can lift the UIM but he won't go off
so, i've disconnected the following lines...
3 little vacuum lines in front of the UIM
1 big line which is going to the brake booster in back of the UIM
1 oil rod (?)
the connector for the BAC, TPS and air intake temp sensor...
i can see a line which is going from the bottom of the UIM into the top of the engine... is this the cooling line which was mentioned from higgi? (this line really sucks, it won't pop off)
have i forgotten anything?
can anybody give me a checklist like above for reinstall? i hope the car will run again lol :/
which bastard has constructed this engine? i've worked on several bmws, audis and vw's, but never get fu**ed so hard like the past 2 days

That coolant line you are talking about ...I had to cut off to remove the UIM. I still haven't been able to remove the remaining pieces though. I think I'll have to use a razor and slice a cut down the side. It's a good idea to replace it while your there though.
