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
