The Peugeot 307 SW (2005-2008) is an estate with a panoramic glass roof and electrically operated roof shade. Its electrical distribution changed during 2005: the Peugeot owner’s handbook of 28 February 2005 uses an earlier cabin and Maxi fuse list, whereas the 1 October 2005 handbook and 2007-2008 documents describe different accessory and high-current supplies. All 101 source entries, including 14 quick-reference rows, are retained in seven separate tables rather than merging incompatible ratings.
Where are the Peugeot 307 SW fuse boxes?
Passenger compartment: Switch the ignition off. On a left-hand-drive car, locate the lower dashboard fuse cover on the driver’s side, turn the latch a quarter-turn and lower the flap carefully. The plastic fuse puller and spares may be attached to the cover. Right-hand-drive handbooks can instead specify access via the passenger glovebox. The adjacent BSI module should not be unplugged to check a fuse.
Under the bonnet: Find the covered engine fuse carrier next to the battery, release its catches and locate the standard F-series sockets and the separate high-current MF links. Some engine panels have two physical carrier variants; F15-F18 are specified only for the type 1 arrangement. On later cars an F41 position may serve the six-speed automatic gearbox. Always close the box lid tightly against moisture.
Distinguishing the early and facelifted electrical layouts
The simplest test is the luggage-compartment 12 V socket: in the early 2005 SW it uses cabin F8 at 20 A, while the front socket uses F9 at 30 A. From late 2005, both sockets are powered through F9 at 30 A. Early cabin F12 is unused, while the later F12 is a 15 A feed to parking assistance or driving-school equipment. Under the bonnet, starter control F8 has 20 A in the 2005 documents but can be 25 A in a later 2007.5 manual. Do not increase a fuse rating without confirming the fitted circuit.

Later 307 SW Maxi fuse ratings
The post-update layout uses MF3 30 A for ABS/ESP valves, MF4 and MF5 80 A each for BSI supplies and MF6 80 A for the cabin fuse board. They cannot be exchanged with the February 2005 MF ratings solely because the carriers look similar.
| Pozycja | Amperaż [A] | Chroniony obwód / funkcja |
|---|---|---|
| MF1 | 30 / 50 | Radiator cooling fan, 30 A for a 200 W assembly or 50 A for a 400-460 W assembly |
| MF2 | 30 | ABS/ESP hydraulic pump |

Rear socket, tailgate wiper and panoramic shade problems
Rear 12 V socket does not work: Check early cabin F8 (20 A) or late F9 (30 A). If the front socket still works, inspect the rear outlet and its boot-side wiring. Rear wiper stops: Cabin F1 (15 A), followed by the harness in the tailgate hinge and motor connections.
Roof blind is stuck: F5 (30 A) serves front windows and the panoramic shade motor, while F7 (5 A) protects auxiliary shade controls in the early system. This is not the hydraulic roof of a 307 CC. Rear demister fails: Cabin F17 (40 A), rear-glass connections and the heater grid. Starter does not turn: Check the car’s actual 20 A or 25 A engine F8 rating, battery earth strap and starter solenoid rather than inserting a larger fuse.
Parking sensor warning: Later F12 (15 A) is an appropriate supply check. Blower not operating: Under-bonnet F11 (40 A) and blower speed controller. ABS light: Verify correct MF2/MF3 power feeds for the production version and diagnose the wheel sensors if the supply is sound.
Other Peugeot fuse layouts
Compare the conventional Peugeot 307 Break (2005-2008), the older Peugeot 307 SW (2003), the Peugeot 307 (2001-2004) and the folding-roof Peugeot 307 CC (2006-2008). Their electrical equipment and Maxi fuses are not universally interchangeable.
