I decided to take my car to a strictly Mercedes repair shop where they had the STAR diagnostic tool. They did a thorough analysis of the car and they said there are no ABS brake codes. The only error came from the ESP where it said the possible cause is the multipole ring which is shop talk terminology for the wheel bearing seal. They cleared all the possible codes on the car and when they inserted the key into the car, the 'ABS & ESP inoperative' error message came up despite the car not moving. If I move forward with the repair with the shop it'll be the 3rd time doing the wheel seal. Should I just suck it up and buy a genuine MB wheel bearing hub that has the bearings and seal in it so I don't have to deal with the wheel seal issue? I'm at a point where this is a likely choice.
