February 9, 2009
Vehicle Information
Condition
The customer may report that personalized memory settings (for example, electric exterior mirror, seat memory, radio, air conditioning,
electric steering wheel, etc.) are inoperative or incorrectly assigned when using the remote key.
Technical Background
The memory settings for each key are stored in the individual control unit (depending on the function) and not in the key itself.
Only the identification of the currently used remote key is transmitted on the CAN bus. Each participating control unit sets its own
adjustments.
Production Solution
Not applicable.

To rule out the key as the root cause, check whether the remote key is correctly identified by the vehicle.
TIP:
Only keys on positions 1 to 4 are included in the personalized memory settings functions. Keys from position 5 cannot be personalized.

- A4 (B7), A4 Cabriolet: Check MVB 7 in the convenience control unit (address word 46).
