I agree that the E83 X3 (with conventional coil springs on all four corners) presents a handling feel more like a car.

Our E53 X5 (4.4i) handles great for an SUV, but you still know you're driving a substantially heavier machine. Ours has rear air-springs and conventional front coils. I've noticed that when the air suspension is working perfectly, I can kick the rear out a bit when transitioning into sweeping corners. That is, the rear outside air-spring appears to maintain more stiffness than otherwise expected, and I'd guesstimate (as a former racer) more transitional stiffness than a comparable coil spring with the same effective steady-state spring rate. Perhaps the controller adds some anti-roll effect? We don't have the air-springs on all four corners like the 4.8 did (not sure if a separately available option), so I'm not sure how that plays out on yours. My guess is that the front air-springs (not to mention the adjustable ride height) could change the front-to-rear balance a lot, particularly in transitions (versus steady-state cornering).

Our E83 threw a DSC code, but our local indy said we can replace the piggy-backed controller without opening the hydraulic side. If so, it looks like a tight fit so I wish I'd tried when the intake was already off for the starter replacement. Anyway, I believe the appropriate software tool is needed either way (that is, for recoding and/or bleeding).

I'm currently doing a quick overhaul on mine. Fixing reluctor rings, swapping in a new to me transfer case and hoping it works. You know, regular x3 stuff. Also working on a preventative rust abatement stuff since I live in the rustbelt of upstate ny.

I thought I should add that the car runs great at 150k. It is the pinnacle of bmw's development of the m54. It's nice to know that under better than normal care 250k on the engine shouldn't be hard to reach.

Yeah, they are out there on the roads...last week I was on the hwy going about 65mph in the 04 and out of nowhere a young lady fires up out of nowhere next to me in a white 04 2.5. She waved,,,I waved...the car was clean and we got overtaken in the wave of traffic.

I still see a number of them. Mine is technically still on the road but has been in a shop (front diff died after 203k miles). Ready for it to be back to give it some additional loving and get her back going. 2004 X3 2.5i with the 6MT.
