2004 X5 E53 3L D- turbo or injektor problems?

If you do find split or damaged vacuum hose, I’d suggest getting some silicon replacement. It does the same job but takes heat,chemical,age damage a lot better..... and on top is much cheaper! (And if you want a funky colour you can.... but I just suggest the standard Black!)

Also if you find one split or damaged you will likely find the rest are on their way out! So just do all of it while your in there. BMW diesels are so sensitive to vacuum leaks it seems.

3mm internal diameter will work as I think the rubber OE stuff is 3.5mm ID (correct me if I’m off!) but it’s dirt cheap by the meter on a popular auction site. I actually rerouted my 535d’s hoses to avoid hot components. That buggar has about 3-4m of vacuum line with the two turbos lol

Be careful using silicon hose for vacuum lines - some silicon hose is not very rigid and can actually collapse under vacuum...
