I have an SMG Hydraulic Unit for sale. This came out my 2004 BMW M3 in February 2019 from an SMG to Manual conversion performed by kaiv.
SMG Hydraulic Unit/Pump (21532229715)
~56K Miles.
Replaced under warranty by BMW at ~43K miles (invoice can be shown upon request), removed at ~99K miles.
Condition
Perfect working condition prior to removal, as pressure tests shows. Pictures show before and after of the label after I stupidly tried to clean it using brake cleaner. You can see I took one wipe on the top and immediately stopped.
Located in the Bay Area and only doing local pickup. Will also be at Laguna Seca on 7/5 if anyone from SoCal wants to purchase it there.
Let me know if you have any questions!
