Instruments - 2001 and Up: Other Audi A6 C5 facelift

Notes on exchanging instrument cluster

1. Do not disassemble instrument cluster.
2. When the replacement of a malfunctioning instrument cluster is necessary, follow exchange part procedures.
3. Complete report form and return together with inst. cluster.
4. Use the original packaging from the new cluster when returning modules.
5. The instrument cluster must be coded according to market and equipment versions See «CODE CONTROL MODULE (FUNCTION 07)»(ref-196304-S26400744462005100900000) .
6. The odometer reading must be adapted to the new/exchange instrument cluster using the VAS 5051 tester See «VAS 5051 TESTER, CONNECTING»(ref-196304-S07611429162005100900000) .
7. Anti-theft immobilizer functions supported by the instrument cluster must be adapted to the Engine Control Module (ECM) using the VAS 5051 tester See «ADAPTATION AFTER REPLACING INSTRUMENT CLUSTER»(ref-196304-S18551168802005100900000) .

Malfunction message "dEF" on trip odometer display

If the control module in the instrument cluster detects a malfunction in its permanent memory, the letters "dEF" will appear on the trip odometer display.

1. If "dEF" is indicated on display, replace instrument cluster. See «INSTRUMENT CLUSTER, REMOVING AND INSTALLING»(ref-196300-S29162299302005100900000) .

Instrument cluster, removing and installing

Removing

Note. It is not necessary to remove the steering wheel to remove the instrument cluster.

If replacing a malfunctioning instrument cluster with a new one, note odometer reading on existing cluster prior to removal.

1. Determine input values for replacing instrument cluster (i.e.: SRI values etc. where applicable): See «INPUT VALUES FOR REPLACING INSTRUMENT CLUSTER»(ref-196304-S09471942522005100900000) .
2. Adjust steering wheel completely out and downward.
3. Press cover -1- upward at side and then remove cover from instrument panel.
4. Remove Phillips head screws -1-.
5. Pull out instrument cluster toward front.
6. Cut cable ties at rear of instrument cluster.
7. Unclip securing latches of connectors and disconnect connectors.

Installing

Installation is reverse of removal, noting the following

1. Connect electrical harness connectors and affix wiring harness to rear of instrument cluster with cable ties.
2. After installation, perform a function test of the instrument cluster.
3. If the function test is OK, enter the input values for the instrument cluster (i.e.: SRI etc. where applicable): See «INPUT VALUES FOR REPLACING INSTRUMENT CLUSTER»(ref-196304-S09471942522005100900000) .
4. Code instrument cluster according to market and equipment versions using the VAS 5051 tester See «VAS 5051 TESTER, CONNECTING»(ref-196304-S07611429162005100900000) .
5. Adapt odometer reading to new/exchange instrument cluster using the VAS 5051 tester See «VAS 5051 TESTER, CONNECTING»(ref-196304-S07611429162005100900000) .
6. Adapt anti-theft immobilizer functions supported by the instrument cluster to Engine Control Module (ECM) using the VAS 5051 tester See «ADAPTATION AFTER REPLACING INSTRUMENT CLUSTER»(ref-196304-S18551168802005100900000) .

Vehicles with front wheel drive

Sender for fuel gauge is located below the floor cover of the luggage compartment.

1. Unscrew cover for connector flange below the luggage compartment carpet. NOTE: To do so, remove luggage compartment floor on the Avant. See «CARGO AREA FLOOR TRIM AND SUPPORTS (AVANT), REMOVING AND INSTALLING»(ref-196286-S22068532592005100800000) .
2. Carefully disengage and disconnect 4-pin harness connector (arrow).

Scheme 6

Note. Terminal assignment for vehicles with front and all wheel drive is identical.

Vehicles with all wheel drive

For vehicles with all wheel drive, the three senders for fuel gauge are connected in sequence.

1. The central connector for all sensors is located on right below the rear seat bench.
2. Remove rear seat bench. See «SEAT BENCH, REMOVING AND INSTALLING»(ref-196287-S04747218032005100800000) .
3. Unscrew cover for connector flange at right beneath rear seat bench
4. Carefully disengage and disconnect 4-pin harness connector (arrow).

Scheme 7

Note. Terminal assignment for vehicles with front and all wheel drive is identical.

Consumption signal, checking (engine at powertrain CAN-bus)

Note. On some engines, the consumption signal is transferred from the Engine Control Module (ECM) to the instrument cluster via the powertrain CAN-bus. Malfunctions in the communication between Engine Control Module (ECM) and instrument cluster can only be detected via On Board Diagnostic (OBD) (DTC 01312 and 01314).
