The 2003-2004 Peugeot 307 SW uses the T5 panoramic-roof estate electrical system, but its model-year manuals are not identical. The official Peugeot editions dated 14 April 2003 and 15 March 2004 establish a separate 2004 F27 airbag fuse and different Maxi cooling-fan options. This reference keeps all 65 technical rows across the two cabin panels, engine fuses and eight Maxi links, together with eight fault-finding cross-references.
Access to the dashboard and engine fuse boards
With the ignition off, look beneath the driver’s lower dashboard in a left-hand-drive SW. Rotate the fuse-cover catch a quarter-turn, lower the flap and use the puller inside. The 2004 version adds F27 above the main fuse row. Under the bonnet the other covered carrier is immediately alongside the battery; unclip it and replace the waterproof lid carefully after checking its F1-F18 positions. Maxi links require the manufacturer’s workshop procedure.
Commonly requested SW circuits
These eight rows repeat the complete assignments below. Cabin F2 is the rear wiper, whereas engine F2 is the petrol fuel pump. The lighter and front 12 V outlet also have separately listed accessory and illumination circuits.

Passenger-compartment fuses in 2003
F7 (30 A) powers courtesy lights, the front socket and panoramic blind controls, F11 (20 A) the radio and multifunction display, and F16 (10 A) parts of engine and safety electronics. The F19 position is a PARC configuration shunt, not a normal 30 A blade fuse. The following early dashboard drawing is retained from the source.

2004 passenger fuse board – new F27
The March 2004 owner’s manual retains most of the earlier assignments, but adds F27 at 10 A for SRS/airbag equipment at the top of the dashboard carrier. The diagram below specifically identifies that extra position rather than disguising an older 2003 scheme as a 2004 box.

Maxi fuses – 2003 versus 2004
MF1 is 50 A in the April 2003 list; the March 2004 edition distinguishes 30 A for the 200 W fan or 50 A for the 460 W fan. MF4 and MF5 are 70 A BSI supplies. MF6 is 20 A for heated seats in the official April 2003 handbook, but unused in the March 2004 edition. This corrects the omission in the original Polish year-comparison table. Do not populate an unused socket solely because a neighboring model does.
| Pozycja | Amperaż [A] | Chroniony obwód / funkcja |
|---|---|---|
| MF1 | 50 / 30-50 | 2003: 50 A cooling fan; 2004: 30 A for a 200 W fan or 50 A for 460 W |
| MF2 | 30 | ABS/ESP hydraulic pump motor |
| MF3 | 30 | ABS/ESP solenoid valve supply |
| MF4 | 70 | First high-current BSI (built-in systems interface) supply |
| MF5 | 70 | Second high-current BSI supply |
| MF6 | 20 / – | 14 April 2003 manual: heated seats at 20 A; 15 March 2004 manual: unused. Corrected against the manufacturer |
| MF7 | 30 | Ignition switch main supply |
| MF8 | 70 | Electric power steering pump high-current supply |
Practical SW electrical checks
Front 12 V outlet fails: Cabin F7 (30 A); rear 12 V outlet: cabin F10 (15 A). Cigarette lighter illumination/control: Cabin F12 (10 A) also supplies related switch-lighting circuits. Audio and display dead: Cabin F11 (20 A) and F24 (15 A).
Panoramic blind not moving: Inspect the F7/F9 feeds, switch and blind drive. Tailgate wiper: Cabin F2 (15 A) and hinge-harness wiring. Airbag warning in 2004: Check the additional F27 (10 A) and then have the SRS module properly diagnosed rather than bypassing any protection.
Peugeot 307 variants and model years
The 307 SW (2002) uses earlier 20 A F7 and 60 A MF4 allocations. A dedicated 307 SW (2003) entry also documents the April manual. The conventional 307 Break (2002-2004) and later 307 SW (2005-2008) require their own body/production diagrams.
Technical basis: Peugeot 307 SW official manuals dated 14 April 2003 and 15 March 2004. Ratings and diagram assignments are specific to those handbook editions.
