You mean the vacuum pump... VDO. no other way around. Been there tried that.
Just buy used vacuum pump on ebay.
Correct. No individual internal part available, from either MB or OEM
(I thought sometimes it is Bosch but I may remember wrong). Anyway, I
tried too. Same MB part # on the pump assembly outside but different
internal design in the motor. Don't waste your time.
One of the pump I disassembled was made from graphite (like the lead in
2B pencil). That surprises me. I thought that is too soft to last but
maybe easy/cheap to make.
