Adaptation after replacing instrument cluster

NOTE:

The instrument cluster (with integrated anti-theft immobilizer) is adapted to the Engine Control Module (ECM). If the instrument cluster is replaced, the new instrument cluster must be re-adapted to the Engine Control Module (ECM).
After adapting the instrument cluster to the Engine Control Module (ECM), vehicle key adaptation must be performed. Refer to Adaptation of vehicle keys .
If no authorized ignition key is available, but the 7-digit PIN is available, new ignition keys must be made and adapted to "Adaptation after replacing instrument cluster".
Adaptation can be interrupted using the "C" button.

Requirements

VAS 5051/5052 tester connected and vehicle On Board Diagnostic (OBD) selected. Refer to VAG 1551/1552 Scan Tool (ST), VAS 5051 Vehicle Diagnostic Testing and Information System or VAS 5052 Vehicle Diagnostic and Service System, connecting and selecting functions .
Ignition switched on.

Procedure

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 remanufactured instrument cluster is being installed, it must first be switched free via a login procedure. Refer to Login Procedure (function 11) . 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 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:
