Produced with original Integration level 18-03-5xx.

SITUATION
When a short test is performed as part of a workshop visit for an unrelated situation, the following fault code is
found stored in the Body Domain Controller (BDC) memory:
• "0x804417 - Motion sensor (MEMS) in key: failure"
Note: There will be no customer-facing indication of this stored fault and/or any related key or vehicle
malfunction present.
MEMS is the chip for the motion sensor in the vehicle remote and/or display key, to prevent vehicle thefts. Keys
with MEMS were introduced in all listed vehicles as of the factory I-level 18-03-5xx.

CAUSE
MEMS sensor in the remote key transmitter version 2.1.
Remote keys can be differentiated between version 2.1 and the
earlier version 2 by removing the back cover.
Carefully check the ID printed in various places (circled). G05 basic
remote key shown; other models similar.


ID21= version 2.1 (contains motion sensor)



ID2= earlier version (no motion sensor)

The fault code can sometimes be created erroneously. In the case of a fault memory entry, it is not evident
whether the fault is erroneous or actual.

Follow the procedure below to determine if the MEMS contains an actual fault, or if is simply an erroneous fault.

PROCEDURE
Attention: There must be no second remote key within range. If a second key is present, move it at
least 5 yards away from the vehicle.
Test sequence:
1. No other vehicle remote key is within 5 yards.
2. Vehicle is unlocked.
3. Deactivate Comfort Access via the iDrive menu path--> Auto -> Settings -> Doors/vehicle access ->
Comfort Access -> Deselect:
• Unlock when approaching
• Lock when walking away
4. Move at least 5 yards away from the vehicle.
5. Lock the vehicle using the remote key’s lock button.
6. Leave the key on a stationary surface so that it remains motionless for at least 3 minutes.
7. After 3 minutes, bring the key to within 1 yard of the side of the vehicle, but do not open/unlock.
8. Set the key down motionless for 3 more minutes (e.g., at rear of hood, on roof, etc.)
9. After at least 3 minutes, attempt to unlock the vehicle via Comfort Access at the door handle. Do not
move the remote key.
• Unlocking should NOT occur if the MEM is functioning properly
10. Move the key. Attempt to unlock the vehicle via Comfort Access.
• If the vehicle unlocks, the MEMS is functioning properly
Conclusions:



• If the vehicle unlocked before the key was moved at Step 9, repeat the test.
• If the vehicle can still be opened before the key was moved (at Step 9), it is likely that the MEMS in the
key is faulty. Replace the remote key.
o Refer to Repair Instructions 66 12… “Teach in radio remote control/radio remote control with display
(BMW display key)”
Note: The MEM deactivates the lock/unlock function after approx. 2 minutes with the key stationary.

For this reason, the test sequence calls for a 3 minute wait to determine if the MEM is actually faulty or not.
11. If another remote key is available during this workshop session, repeat the test sequence to confirm
proper MEM operation.
