Technical features of the instrument cluster
The instrument cluster is equipped with a flexible Service Reminder Indicator (SRI), that is, the instrument cluster evaluates various service requirements of the vehicle based on input quantities such as driveability or oil consumption, (not for USA)
For the standard SRI (with set intervals that could not be influenced by how the vehicle was driven) the service interval was set to 30,000 km or 12 months, and the oil change service was set to 15,000 km.
The maintenance interval extension (MIE) is capable of reproducing the functions of the standard SRI, when the limits are set correctly. The limits are variable however. The MIE is also capable of evaluating the oil temperature sensor. Adaptation channels in the VAG On Board Diagnostic (OBD) make this possible.
In countries where the standard SRE is still used, such as the USA, the following adaptation values must be entered:
| Channel 42 (minimum mileage performance) | 8000 mi |
| Channel 43 (maximum mileage performance) | 8000 mi |
| Channel 44 (maximum time interval until next service) | 365 days |
| Channel 45 (oil quality) | 1 |
The instrument cluster in the Audi A6 Highline comes standard with the driver information system.
The speedometer contains an LCD display for the odometer and trip odometer. The service reminder indicator (SRI) is shown in the center display.
The warning/ indicator lights are integrated in the speedometer and tachometer.
The instrument cluster is controlled by a microprocessor and has extensive On Board Diagnostic (OBD) capabilities. If malfunctions occur in any of the system components, corresponding Diagnostic Trouble Codes (DTC) are stored in the DTC memory of the instrument cluster. These can then be identified using the VAG1551 or VAG1552 Scan Tool (ST).
