Opel Astra K (2016), also known as the Vauxhall Astra Mk7, is the fifth-generation Astra launched in 2015. This reference describes an early 2016 model-year installation with 57 engine compartment fuse positions, 37 cabin positions and 22 rear luggage positions. Later facelift, petrol, CDTI diesel, hatchback and Sports Tourer variants can differ in fuse population, especially electronic headlamps, powered seats and comfort modules.
This English article preserves all 116 source rows in three complete tables, including unused positions, optional equipment and three original fuse drawings. The Polish source does not provide universally verified ampere ratings. Each rating is therefore marked “-” rather than guessing or copying values from another Astra generation.
Where are the Astra K fuse boxes?
Engine compartment: the covered fuse holder is on the front left near the battery. Switch off the ignition, release the clips and lift the cover vertically. Passenger compartment: on left-hand-drive cars, open the service access in the lower dashboard near the steering wheel. On right-hand-drive vehicles, the fuse access may be behind the passenger-side glovebox. Luggage compartment: behind the left side trim. Lift the access cover or trim panel, and first verify that the optional rear electrical module is actually fitted.
Astra K 2016 engine compartment positions 1-57
Frequently checked circuits include starter 1 and 2, ABS 22, front/rear washer pumps 23, heated rear window 29, horn 34, boot 12 V outlet 35, fuel pump 43, rear wiper 48 and front wiper 54. Halogen versus LED headlights and automatic levelling use different positions. The source contains isolated stray numbers ahead of the descriptions for positions 27, 38 and 41; these are not extra fuse locations.

Astra K 2016 luggage compartment fuse positions 1-22
Depending on hatchback/Sports Tourer equipment, the rear unit contains trailer power at 3, 16 and 17, power passenger seat at 4, distance-warning module at 6, heated rear seats at 9 or 13, front-seat heating at 12, heated steering wheel at 14, ventilated seats at 15 and power-folding seats at 21. Some seat-heater fuse positions are alternatives depending on whether a theft-alarm siren is fitted, so don’t install additional fuses into unoccupied slots.

Astra K 2016 fuse box FAQ
Which fuse is for the cigarette lighter?
Cabin fuse 4 in the documented 2016 installation. Confirm its fitted ampere rating before replacing it.
Which fuse protects the windscreen wipers?
Engine-bay position 54 for the front wiper, and engine position 48 and cabin position 31 are associated with the rear wiper.
Where is the luggage compartment power outlet fuse?
Engine compartment position 35 in the source chart.
Can this diagram be used for the Astra J?
No. The earlier Opel Astra J 2012-2013 has different fuse-box assignments and circuit numbers.
For a related Opel electrical layout compare Corsa F as a separate guide, not as a substitute fuse chart. Fit the correct factory fuse type and amperage only; repeated failures require checking the wiring and connected components.
