These instructions apply to the Audi A4 Mk5 (B9/8W) 2015-Present. For other models, please choose your vehicle here.
Last updated:
When the spanner or a “Service” / “Inspection” message appears on your Audi A4 (B9/8W, 2015–present), a service interval has elapsed. The quickest DIY route is the trip-reset button. Do the oil and filter change before you reset it.
Reset Only After the Service
The interval measures distance and time since the last reset, so clearing it early just hides the reminder while the oil keeps ageing.
How to Reset Using the Trip Button
- Turn the ignition off.
- Press and hold the reset (0.0) button — the trip-reset on the wiper stalk or instrument cluster.
- While holding it, switch the ignition on.
- A service-reset prompt appears — release the button, then press it again (or the OK/menu button) to confirm.
- If oil and inspection are tracked separately, repeat for the second prompt.
If the Button Method Doesn’t Offer a Reset
Some B9 cars only expose the reset through diagnostics. If the trip-button prompt doesn’t appear, the service indicator is reset with a VCDS/OBD tool or at a dealer. The MMI Vehicle → Service & checks menu still shows the remaining intervals.
If the Reminder Returns
- It reappears at start-up — the confirmation wasn’t completed; repeat and confirm.
- A different warning is on — that’s a fault, not the service timer.
Frequently Asked Questions
Where is the reset button on the Audi A4 B9?
The trip-reset (0.0) button on the wiper stalk or cluster — the one you use to zero the trip.
Can I reset the A4 service light without a tool?
Often yes, via the trip-button method. If no prompt appears, an OBD tool or dealer is needed.
Does the engine need to run?
No — ignition on, engine off.
Why are there two messages (oil and inspection)?
Audi tracks oil-change and inspection intervals separately. Reset whichever is prompted; do both after a full service.
If a warning light appeared with the service message, look it up on autodtcs.com. After battery work, see our A4 B9 battery guide.
