Adaptation after replacing instrument cluster: Procedure

WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2005 Audi allroad, 2004 Audi allroad, 2004 Audi A6, 2003 Audi allroad, and 2003 Audi S6. However, it is still accessible from the selected car via links, so may be relevant.

Insert old (authorized) ignition key into ignition lock and switch on ignition.

Replacement part instrument clusters already have a 14 digit identification number (this is necessary if instrument cluster and Engine Control Module (ECM) are being replaced simultaneously). During adaptation of the instrument cluster to the ECM, this number is transferred to the ECM.

NOTE: If a used or re-manufactured instrument cluster is being installed, it must first be switched free via a login procedure. See LOGIN PROCEDURE, INSTRUMENT CLUSTER . The 7-digit PIN for this must be determined via the 14-digit identification number of the used instrument cluster. Continue as follows after successful login procedure:

Enter adaptation value Input value: 0 to 65535

Enter previously determined 7-digit PIN (of Engine Control Module (ECM)) in button field -2-.
Press -Q- button to confirm input.

NOTE: If the 7-digit PIN is entered incorrectly three times, tester display will indicate "locked 10". This locking time can also be indicated in measuring value block 024 (display field 2). Adaptation is now locked for 10 minutes. This time is doubled after every third consecutive incorrect attempt, up to a maximum of 255 minutes.

Wait until the next indication appears on display.

NOTE: If a malfunction occurs during adaptation, the following DTCs can be displayed:

"Interference": CAN-bus not available or engine speed recognized (adaptation only with the engine standing still).

NOTE:

"Adaptation not OK": Engine Control Module (ECM) cannot give out data (17-digit VIN, 14-digit identification number), since the control module is still new (factory condition) or the data is faulty.
"System not OK": Engine Control Module (ECM) does not give out data, since it was previously used with a control module (instrument cluster) in another performance class (tuning-protection)
"Key not OK": Data cannot be given out or accepted, because no key or no matching key is available.

If no malfunction is present, this display appears:

The warning light will go out approx. 2 seconds after successful adaptation and a short confirmation signal will be given (0.5 seconds light off, 0.5 seconds light on, light off).

End function "10 - Adaptation" by pressing <-- button.

Adaptation of the immobilizer to the Engine Control Module (ECM) has been completed.
