Hi there, this is my first post on this forum so bare with me
So I have a 2004 BMW 320i, stock no modifications or anything. Over the past year, i've felt my car becoming slower and slower in its acceleration, until now its gotten to the point that it cant even out run a minivan. The car is in great condition physically, and all fluids have been changed and checked.
More recently, whenever I give the accelerator a little tap, I hear a whistling noise coming from the engine compartment, but only lasts a quick second. If I continue to tap on the gas, the car will stall. If i simply hold the accelerator down to about 1000rpm, the RPMs will fluctuate. (Vacuum leak?)
With a WOT, the RPMs seem sluggish up until around 4K where then they just jump and the car really takes off, accelerating in 2nd gear with WOT (steptronic) its faar more slower then usual.
0-100km/h takes about 12 seconds now, and im quite sure that is very slow for this car. I've been told that it could possibly be a VANOS problem, a vacuum leak, or the car just may be in need of Software update. I'd really like your opinions on this.
I have provided a link to a video that I made of my problems to give you a better idea of what im talking about, I dont seem to find my issue anywhere on the boards.
