For those who would rather purchase the Special Tooling from BMW than remove the door panel, this process should take less than 15 minutes.

- remove plastic access plug from rear edge of door
- use special tooling per TIS to unlock and pull metal slide towards rear of car (see photo, blue circles highlight the portion that holds than handle in place, though they are slid over in the photo)
- pull handle down, then out
- disconnect light source (fiber optic tube for 2002-2004, LED for 2005-2008) and comfort access electrical connection

Comfort Access handles are common to fail, see SIB 66 03 06 Comfort Access Function is Inoperative. I've personally seen 3 different failure modes; hand sensor fails leading to delayed unlock response, handle antenna fails leading to no door unlock or lock, internal handle short leading to current draw and battery drain.

E65, E66 (7 Series) with option 322
Vehicles produced to February 2006

The Comfort Access function is intermittently inoperative. The vehicle doesn't lock or unlock from outside.
There are no faults stored.

Cracked and corroded circuit board inside exterior door handles. The problem occurs at the soldered joint where
wire is attached to the circuit board.

Install an improved door handle on affected door.
The improved part can be identified by the date on the
label (date is shown in dd/mm/yyyy).
This could be the shipping date (Versanddatum) or the
manufacturing date (Produktionsdatum).
The manufacturing process was changed from
February 16, 2006 on.
All parts from that date on are improved and can be
