Hey all,

My 530d has a vacum controlled turbo and recently i have a problem, when boost comes at around 2kRPM,
then I feel it going away at somewhere 2.5-3k and then coming back around. I feel this as power stops and rpms doesn't rise quickly,
sometimes even drops to 2k If I press it in high gear.
Also I feel judder when going uphill in 2nd gear at 2-2.3k RPMs. and Check Light came on recently, "Increased Emissions" didn't plug it in
yet but last time I plugged it in dealership they told me no faults, Engine runs smooth just Mass Air Flow sensor is messing a bit.

Any thoughts whould be appriciated. I'm also thinking that my vacum lines could be messing up or actuator(maybe wastegate stuck) Does anyone have
P/N for the vacum lines?

Thnx
