Hey how are you
what you asking for answer not being a guess will require more info from you
the shocks & sensors replaced is good as long as there connection is good on the sensor and not causing the light to stay on and can switch mode
but assuming the job is done right that leaves the
ABC module ( Active Body control module)
In fuse and relay box, left side
This module control the suspension programming , if you cant switch modes
a star scanner or equivalent will be necessary to confirm and you don't want guesses
if that shop has the a capable scanner he can pull up that data and actually control the suspension and test the shocks the sensors & the module itself
The dealer will charge 1 hour labor and you can be sure ,it will be $100 at least .
now you want confirmation For $30 ,for something should cost $100 to confirm .
Hope you can see my point that the confirmation request is not possible from me especially if i m not next to the car and using my scanner to confirm
Please let me know if that works for you
