Guys here is a picture , Item number 13 shows Pressure reservoir! anyone knows, if there are any other names for this part and if its possible I need the part number for this item. dealership is telling me its an ASR pump, and the one they brought to the counter has plugs on it. The one in my car doesnt have any plugs on it. Picture shown is for W140, however I have this exact part on my SL.

Item 13 is located right behind the drivers side wheel. Picture doesnt show clearly.
