November 10, 2008.
Supersedes Technical Service Bulletin Group 91 number 07-34 dated August 10, 2007 for reasons listed below.

Affected Vehicles
91 Telematics system, switching off emergency battery

Condition
The emergency battery needs to be switched off.
Technical Background

Vehicles with Telematics system are equipped with an emergency (back-up) battery that provides auxiliary power to the Telematics control module inthe event the vehicle battery goes dead or becomes disconnected.

In order to avoid unnecessary discharge of the Telematics emergency (back-up) battery, it should always be switched off prior to disconnecting thevehicle battery and switched back on after the vehicle battery is reconnected.
Production Solution

Audi Telematics by OnStar is available as an option on all A4, A6 and A8 models beginning with 03.02 production.
Service
Emergency Battery, switching off/on:
Refer to step-by-step procedure in Repair Manual >> Communication >> Repair Group 91.
Warranty
This TSB is informational only and not applicable to any Audi warranty.

The display of A/C control head -E87- (and exterior temperature display in instrument cluster) for version up to index "K" can be changed from to and vise versa by pressing the "Temperature left" (driver-side) with "circulating air button" pressed. The unit of display ( or ) for A/Ccontrol head -E87- as of index "M" is determined via the adaptation of the control module in instrument cluster (and transmitted to -E87- via thedatabus-system).

NOTE:

-

30 minutes

-E87- can be operated for a certain time (up to about ) after switching off the ignition by pressing the "Rest" button (residual heating).Operating time depends on charge condition of battery maximum about .10 minutes

- For vehicles with Nippondenso compressor only A/C control heads beginning with Index "C" are to be or will be installed.

­If -E87- remains in operation after switching off the ignition, test cable connection to connector E terminal 7 for short circuit to positive(connection for auxiliary heating mode not foreseen for USA/Canada) using wiring diagram.

- Remove center part of instrument panel

- Press tabs to unlock and disconnect connectors (arrow).

- When replacing A/C control head note allocation See Page 01-7.

­Illumination of display field and operating buttons occurs via A/C control head with pad number beginning with index letter "M" through lightemitting diodes (LEDs not replaceable).

- During malfunction test of temperature sensor -G56- intake screen of trim should not be closed.

For A/C control head with part numbers beginning with Index "M"

- Remove instrument cluster air outlet, center.

- Remove trim -A- for center instrument cluster.

- Remove radio or radio navigation system.

Adaptation

Individual functions are called up by entering the appropriate adaptation channel numbers (listed in the adaptation table).

NOTE:

­Using measuring value blocks 10,11, 12 and 15, the values that need to be transferred to the new instrument cluster can be read out beforereplacement.

­Adaptation channels 42-44 (see measuring value blocks 13 and 14) do not need to be transferred when replacing instrument cluster, because theyare adjusted by the factory for each new instrument cluster
