Description of the issue at hand
I just took my car to a mechanic (non-Mercedes specialist) that replaced both front wheel bearings. Other than that, no other repair was made. Other than the bearings making noise, the car was driving fine. Brakes were good.
The repair took a few hours and I got back the vehicle which is driving OK from what I can tell. Only thing is that now there is a warning about tire pressure not being able to be measured, ABS + ESP malfunction and such.
The mechanic said that I should probably take it to a Mercedes dealer for diagnosis (he is not equipped for that). But there is no Mercedes car dealer/garage where I live.
This is my first Mercedes and have little experience with the brand. Is this a normal behaviour? Should this warning appear systematically after a bearing repair is operated? Should I be concerned even though the car seems to drive fine?
If I manage to "reset" the fault codes associated with the ABS+ESP+Tire Pressure, will that be enough? (I plan on buying a Launch Creader VII+ or an iCarsoft MB II). Or should I really consider taking it to a far away Mercedes dealer and pay ridiculous amounts of money just for a diagnosis?
