03 E500 brake accumulator

201 6
I am getting an error msg that corresponds to a fault brake accumulator. Please see pic below it is the round piece on the underside of the ABS system which is yellow in color.... left side.

My question is how much of a job is this to replace and would the tech need a star diagnostics system to perform the repair correctly? Thank you.

I thought this part was covered under the 25 year warranty also.
I am going to take it to the dealer and see. From the video its seems a fairly straightforward job but in the vid they do have the Star system.. Thanks to both for the advice!
