Opel Astra J (2012-2013), also known as the Vauxhall Astra Mk6, has separate fuse panels in the engine compartment, the passenger compartment and, on equipped models, the left side of the luggage compartment. The configuration differs between hatchback, GTC, Sports Tourer, petrol and diesel versions, plus optional trailer, alarm and comfort equipment. These tables describe the documented European 2012-2013 setup.
All 112 original positions across three complete tables are retained, including empty slots. The source identifies circuits but does not establish a universal ampere rating across every engine and trim; current values therefore remain “-” and must be checked on the installed car’s fuse and handbook. The three original diagrams are preserved and placed immediately before their respective tables.
Where are the Opel Astra J fuse boxes?
Engine compartment: on the left of the engine bay beneath a rectangular cover. Turn off the ignition, release the catches, lift the cover fully and remove it vertically. Interior: left-hand-drive vehicles have a fuse panel behind the small storage compartment at the left end of the dashboard; open and carefully remove the compartment at its retaining clips. On right-hand-drive cars the access is behind the glovebox. Luggage compartment: on the left side behind a trim cover; in Sports Tourer models lift the relevant side trim before opening the fuse panel. Rear-box equipment depends on body style.
Astra J 2012-2013 engine fuse box, positions 1-54
Common circuits are starter 16, ABS 21 and 30, rear window heating 18, front windscreen wipers 43, rear wiper 14, radiator fans 42, 45 and 48, horn 47 and fuel pump 49. Xenon and halogen headlamp positions differ, as do diesel fuel heating and transmission circuits. Position 30 is an ABS circuit despite an extra stray “0” in the original Polish description.

Astra J 2012-2013 common electrical faults and fuse FAQ
Where is the cigarette lighter fuse?
Cabin position 6 in this documented European model-year layout. Disconnect accessories and inspect the socket before replacement. The original source does not give a confirmed current rating for every variant.
Which fuse protects the front wipers?
Engine-bay position 43. The rear wiper uses engine-bay position 14.
Why is the boot power socket listed twice in some guides?
The Sports Tourer can have an additional rear fuse panel, but its cabin fuse 26 is documented for vehicles without that rear panel. Verify the equipment in the actual car.
Does the Astra K use the same fuses?
No. The Opel Astra K 2016 fuse guide documents a different electrical installation. Do not transfer fuse numbers between generations.
For an earlier, related Opel model see Corsa E; its fuse layout is also model-specific. Replace fuses only with the exact manufacturer’s specified type and amperage and investigate repeated failures.
