Additional Notes
- The Opel Astra L brake fluid specification applies to the hydraulic brake system across both hybrid configurations, the 133 kW DGX and the 165 kW DGY variants introduced in 2021.
- Both configurations share an identical fill specification expressed as a range rather than a fixed volume, with the accepted level falling between the minimum and maximum marks on the reservoir.
- A between-min-and-max specification is characteristic of a top-up or inspection-based service approach, where the fluid level is verified against reservoir markings rather than measured by a precise volume figure.
- The normal use condition applies to both the 133 kW DGX and the 165 kW DGY, meaning the stated level specification is referenced under standard operating conditions rather than a severe or first-change-only scenario.
