Steering pulling left possible issue?

Model: E90 323i, Right hand drive, 2007 M Sport, Stock sport suspension/spring, 18″ OZ RIM

Background:
Replaced lower/upper arms
Replaced upper Strut mount
Done wheel alignment

Symtoms:
Seems the steering wheel try to pull left a bit even on straight highway, need to hold by hand

Possible reason?:
1. Road design, slope to left
2. Wheel alignment need to be done again
3. Wrong placement / missing strut washers (due to replacing upper strut mount)
4. Sticking brake caliper on left side
5. Others.

For point 3 and 4, what can I check/test myself (easy one without jack up the car before going to garage again? e.g. noise? brake smelly? etc.

Attached the wheel alignment report

Maybe you hit a pothole, curb, bump, etc? Sounds like it just needs an alignment again.

Check air pressure, measure from the ground to the top of your fender left and right side they need to be identical. IF they are not it will pull that means your car is leaning. Other item can be a bad steering rack have you ever changed fluid or a flush. Of course final item is go to another place to get an alignment.

My experience a few months ago was i bought a CPO 2011 328IX and it pulled to the left just like yours. I told dealer at the time i was purchasing it and they gave it a wheel alignment. Yes it did help out but it wasn’t perfect. I went back a week later and had a different tech do the alignment and he found the rear being out of align just a little bit and boy did that help. Straight as an arrow.

DO NOT measure from the ground, that will take the tire’s under- or over-inflation into account. To measure ride-height, you measure from the lower lip of the wheel, straight up thought the centerpoint of the rim to the underside of the fender lip. The measurements from left to right can be up to +/- 15mm (Yes, a 30mm range. it might even be +/- 20mm, but I’m pretty sure it’s 15).

FWIW, a difference in ride height in and of itself is not usually the problem, it’s usually indicative of a problem like worn or bent suspension components.
