ahhh, the joys of owning a POS E46.
BTDT with my 2002 wagon. some lock expensive lock control module was the issue.
but then it could be the common wiring harness issue. the bazzillion wires that go from the body to the hatch chafe through and cause all sorts of issues with the excessive electrical parts in the hatch.
be careful trying to get the inner hatch panel off to get to the lock, the attachment points break off 90% of the time and new panels are not cheap.
did i mention how poorly made the e46's were?
(i just finished replacing most of the cheap plastic cooling system parts......yet again)
