SUBJECT
Seat Heater Does Not Feel Hot Enough

MODEL
E70 (X5) equipped with Comfort Seats (SA456)

E71 (X6) equipped with Comfort Seats (SA456)

SITUATION
The customer may feel that the seat heater is not reaching a high enough temperature, even when on the warmest setting.

If the vehicle is compared to a like vehicle, the result is the same. However, if the vehicle is compared to another E70 or E71 without Comfort Seats, the maximum temperature on those seats will be noticeably higher.

CAUSE
The seat heater is functioning properly; however, the set point for maximum temperature in the seat module has been set lower on the Comfort Seat than other X5 and X6 seat variants.

PROCEDURE
Do not replace any parts.

Explain to the customer that the seat heater is functioning properly, but to address his or her concerns, the temperature set point will be increased via an upcoming software update, which will be available during the first half of 2009.

This Service Information bulletin will be updated once the new software is available.
