Finally something positive happened. MB USA approved so the dealer fixed the car.
The invoice was covered by MB goodwill and it shows that 5 parts were replaced :
210-460-25-00 Steering Box (FastLane does not have this part)
and 4 parts 913023-010002 which have no description.
The invoiced also stated that an alignment has been performed as well.
Could somebody help me understand in plain English what the dealer did to the car?
