Switching to a Long Life Service (LLS) interval for your Audi can offer greater flexibility between services. This guide provides information on how to understand your current service interval and potentially reset it using VCDS (Vag-Com Diagnostic System).
Understanding Audi Service Intervals
Audi vehicles typically offer two main service interval options:
- Standard Servicing: Scheduled every 12 months or 10,000 miles, whichever comes first.
- Long Life Servicing (LLS): Scheduled every 24 months or sooner, depending on driving style and conditions. LLS requires the use of specific oil that meets VW 503 01 specifications (or newer, superseded specifications like VW 504.00).
Your vehicle’s instrument cluster displays service reminders based on the currently active interval. If you’re unsure which interval your car is using, VCDS can provide detailed information.
Using VCDS to Check and Reset Your Service Interval
VCDS allows you to access and modify various control modules in your Audi, including the one responsible for service reminders. Here’s a breakdown of how to check your current settings:
-
Connect VCDS: Connect your VCDS interface to your car’s OBD-II port and launch the VCDS software.
-
Select Control Module: Navigate to [Select Control Module] -> [17 – Instruments].
-
Read Data: Go to [Data] -> [Channel 02 – Service Reminder Status]. This channel indicates your current service interval setting. A value of “1” often suggests a fixed interval (like annual servicing), while “0” might indicate a flexible/LLS interval. Other values may represent different service modes. Refer to the Ross-Tech wiki for more detailed information on specific values.
-
Interpreting Data: Examine the values in other channels (e.g., Channel 42 – Min Mileage to Service, Channel 43 – Max Mileage to Service, Channel 44 – Max Time to Service) to understand your car’s current service parameters. Note that a higher minimum mileage than the maximum mileage might indicate an unusual setting that requires further investigation.
-
Resetting the Service Interval (if necessary): In the [Instruments] module, navigate to [Adaptation] and locate the channel related to the service interval. You might find an option for “SRI Reset” or similar. Follow the on-screen prompts in VCDS to perform the reset. Caution: Ensure you understand the implications of resetting the service interval before proceeding. This action resets the service timer and should only be performed after a completed service.
-
Confirming the Reset: After the reset, return to [Data] -> [Channel 02] and verify that the service reminder status has been updated. The mileage and time since the last service should also be reset to zero.
Important Considerations for Long Life Servicing
-
Oil Quality: Using the correct oil specification is crucial for LLS. VW 504.00 supersedes VW 503 01 and is suitable for Long Life Servicing. You can check your oil quality setting in VCDS (e.g., Channel 45 – Oil Quality). However, VCDS only reflects the setting in the instrument cluster and does not analyze the actual oil quality.
-
Driving Style: LLS intervals are variable and adjust based on your driving habits. Aggressive driving or frequent short trips can shorten the interval.
-
Consult Your Manual: Always refer to your vehicle’s owner’s manual for specific service recommendations and oil requirements.
-
Ross-Tech Wiki: The Ross-Tech wiki (http://wiki.ross-tech.com/wiki/index.php/SRI_Reset_Procedure) is an excellent resource for more in-depth information on VCDS and service interval resets for various VAG (Volkswagen Audi Group) vehicles.
Conclusion
Using VCDS to understand and manage your Audi’s service intervals can be beneficial. However, proper maintenance and adhering to manufacturer recommendations are essential for the longevity and reliability of your vehicle. If you’re unsure about any procedure, consult a qualified Audi technician.
