The second-generation Volvo S40 II (2011) is a compact European sedan from Volvo’s P1 family. It has one 36-position engine-bay fuse box beside the 12 V battery and a separate 50-position passenger compartment holder beneath the front passenger glovebox.
This year-specific guide preserves every documented entry, including unused locations, both main schematic drawings and the original featured photo. Volvo S40 models have different fuse populations depending on petrol or diesel engine, USA versus European market, AWD and optional equipment. Never fit a fuse of another rating solely because its position number matches a different model year.
Where are the Volvo S40 2011 fuse boxes?
Under the bonnet: the covered unit sits near the vehicle battery and contains high-current protection for the radiator fan, steering, ABS, starter, climate-control blower and engine. Volvo generally recommends trained servicing for the main fuses 1-18; ordinary smaller protection is in slots 19-36.
Passenger side: another fuse panel is secured beneath the glovebox. Release the lower trim retaining clips and the two panel locks, lower the panel toward the passenger seat, then refit it securely after checking. These positions are numbered 37-86; do not mistake this holder for the driver’s dashboard end fuse panel found on other Volvo generations.
Volvo S40 2011 under-bonnet fuses 1-36
These 36 fuse entries retain their original ratings and year-dependent alternatives. Front windscreen wipers: engine fuse 17 (30 A); blower motor: fuse 10 (40 A); horn: fuse 20 (15 A); engine controls: ECM/TCM at position 23 as applicable. The ABS hydraulic pump at position 7 requires special attention to region and model year.

Volvo S40 2011 interior fuses 37-86
The cabin panel covers lighting, comfort electronics, audio, central locking and the power windows. Fuse 45 (15 A) supplies an interior 12 V socket, fuse 57 (15 A) the OBD II diagnostic connector and brake light switch, and fuse 74 (15 A) the fuel pump relay. The front and rear door window circuits have separate protection.

S40 12 V outlets, windscreen wipers, horn and OBD II
Interior 12 V outlet: glovebox-area fuse 45 (15 A). Rear luggage area outlet: fuse 77 (15 A) on suitably equipped variants, sometimes shared with the Accessory Electronic Module AEM. If only one outlet fails, inspect its own circuit and socket contacts.
Front wipers: engine fuse 17 (30 A); front washer pump: cabin fuse 48 (15 A). Horn: engine fuse 20 (15 A). OBD II diagnostics: cabin fuse 57 (15 A), which also serves the brake switch. Right and left high beams: cabin 58 and 59 (7.5 A each).
Air-conditioning blower: main engine fuse 10 (40 A). Fuel pump relay: cabin fuse 74 (15 A). Electric windows use cabin fuse 63 (right rear), 81 (left rear), 82 (front right) and 83 (front left). A recurring blown fuse requires diagnosis of motor load and wiring.
Volvo S40 2011 model-year and regional differences
The 2011 USA owner’s reference gives 30 A for the engine-bay ABS pump position 7, while some European lists give 40 A. Engine position 6 is unpopulated on the base USA petrol model but can supply diesel glow plugs in Europe. Cabin position 55 is unused in the standard reference, unlike some other years. Optional equipment including heated seats, sunroof, alarm, Xenon headlights, parking assistance and navigation affects which positions are populated.
Compare Volvo S40 2010 and Volvo S40 2012 for adjacent years, or the Volvo C70 II 2010-2013, which shares related components but has different folding-hardtop protection. Do not transfer fuse functions from another model just because the numbering looks similar.
