When the spanner or “Service” / oil-life message appears on your Vauxhall Astra K (Mk7, 2015–2021) — Opel Astra in Europe — the Oil Life System has run down. You reset it from the driver-information menu; no garage tool needed. Do the oil and filter change first.
Reset After the Service Only
The Oil Life System estimates oil condition from how you drive. Reset it only once fresh oil and a filter are in, or it will under-estimate the next interval.
How to Reset the Astra K Service Indicator
- Turn the ignition on (engine off).
- Press ‘MENU’ on the indicator stalk and scroll to ‘Vehicle Information’; press to open it.
- Scroll to ‘Oil Life System’ (remaining oil life).
- Press and hold the menu button AND the brake pedal together for about 3 seconds.
- The oil life returns to 100% — the reset is done. Turn the ignition off.
If It Doesn’t Reset
- You didn’t hold both together — the button and brake pedal must be held at the same time for ~3 seconds.
- A different warning is lit — that’s a fault, not the oil-life counter.
