2015 BMW 3 Series F30 Fuse Box Diagram

Engine compartment, right-hand side close to the windscreen (mirrored to the left on right-hand-drive cars), in the power distribution box under the bulkhead cover. Model year 2015 spans the facelift: cars built until June 2015 are the original F30 and those from July 2015 the LCI with the new B-series engines and LED headlights, yet no source publishes a different allocation card for either half of the year, so the positions below follow card 9 228 158-02 exactly as the 2013-2014 cars have it.

Positions are laid out as the card prints them: the top row 18 to 35 and the bottom row 42 to 56 read left to right, the side columns 57-63 and 64-70 read from the top down, and 36, 37, 38 (standard blades) followed by 39, 40, 41 (mini blades) fill the gap between the relays. Nine sockets are empty: 30, 35, 38, 39, 49, 51, 59, 60, 61.

Beneath the load-floor covering of the luggage compartment, on the right of centre; the card with this car's allocation sits in the pocket on the box. Both halves of model year 2015 - the pre-facelift cars built to June 2015 and the LCI cars from July 2015 - are documented with card 9 228 158-02; no source has published a facelift-specific card for the rear box, so options such as the trailer module (113, 114, 139, 140) still follow this edition.

Positions on the plate: a row 100-104 followed by 105-111 at the top, 112-117 in the middle right, 118-123 lower left, and 124-142 along the bottom, every row counted left to right; the left-hand columns 143-153 and 154-159 and the right-hand column 160-166 are counted downwards. The square housings are relays, not fuses. Vacant sockets: 101, 102, 105, 108-112, 115, 118, 119, 129, 131, 133, 134, 136, 138, 156-158, 166.

Above the battery on the right-hand side of the boot, behind the removable side trim; five fuses sit on the rear electronic module, separate from the main rear box under the floor. Pre-facelift and LCI cars of model year 2015 both keep the REM (the body domain controller that merges it into one unit belongs to later BMW platforms), so the assignment here is the 9 228 158-02 card's.

The fuses stand in one column at the right of the module; count from the bottom up as the slots are numbered: 82 in slot 1, 85 in slot 2, 83 in slot 3, 84 in slot 4, 80 in slot 5. The relays occupy the large housings to the left.
