Steering wheel not centered
Hi,
When I got the car from MB dealer last Tuesday(Transmission and brake fluids replacement), I noticed that the steering wheel auto level slightly to right at stop or very low speeds and car turn left, I did some correction by hand to center it after 3 to 5 mile trip it was centered the whole day. Today I noticed it again, so corrected by hand, after moving from low speed to high speed it was centered again by itself.
Any idea why that is happen and is that normal.
Note: At high speed as all we know the steering wheel will be stiff so the wheel will be at center. At low speed two times happen with me until drive the car for high speed it aligned by itself.

center tracking 🙄
it sounds like alignment work is needed after replacing wear items. Don't bother aligning a loose front end.
Many things can negatively affect the centering...
While around there, replace the short lived stabilizer links. They do not directly affect tracking but help make suspension looseness tighter.
Any maintenance done is one you don't have to worry about.
Show us the front tire wear pattern: wearing inside a bit or a lot?

- wheel pressure need adjustment
- identical tires need check
- 4M clutches need service
- rubber bushings gone soft
- Lane Assist asymmetrically wearing brakes!
- Electric rack has recalls
- SCM does not reliably hold center track
- Outer tie-rods need be aligned
- front subframe bushings
- Rack mount bushings

About the front tires, it is still looking good as not too much mileage on them and was Michelin Pilot sports all season 4 build at late 2021. I will get look for them if something bad. That's happen when I got the car from dealer (I didn't feel it before I go to the dealer), Transmission fluid replacement or brake fluids replacement may touch any part for steering rack.

>>> check cold tire pressure is key!
(34 to 37psi).

- 4M clutches need service no idea what is
- rubber bushings gone soft what is this and how to check
- Lane Assist asymmetrically wearing brakes! Lane assist not available for my car
- Electric rack has recalls no idea if it was replaced in USA before import to Lebanon last year
- SCM does not reliably hold center track Not checked
- Outer tie-rods need be aligned Need to be checked and alignment center
- front subframe bushings what is is
- Rack mount bushings

okay, bump the front pressure to 34 and rear 36Psi.
The tranny ATF service or brake fluid does not involve dealing with the steering.
However if your brake pins are not lubricated (high-temp silicon), it is possible for one wheel to drag on.
That can directly result in not tracking straight.
TEST: Raise car to try to spin tire freely..
Next thing to try is to get a trusted wheel alignment.

Today I have replaced my steering rack due to heavy groaning noise, the rear camera grid lines worked fine and move with steering wheel to left or right. So it could be sensor with rack is not aligned but it is ok with replaced one.
