The first-generation Peugeot 508, sold in Europe from 2011 to 2018, uses two separate fuse boxes within the dashboard and one under the bonnet. The standard saloon and SW estate share much of the basic 12 V architecture, but their rear wiper, panoramic roof and optional equipment can differ. The 2014 facelift retained the familiar F13 lighter and F14 front socket functions; later handbooks publish a shorter engine owner-service list. Below are all 24 technical positions and eight common-circuit references from the original Polish post, using the three original diagrams rather than unrelated pictures.
Peugeot 508 I – fuse box access
Left lower dashboard: Switch off ignition and all electrical consumers. In a left-hand-drive vehicle, open the hinged lower fascia panel on the driver’s side and carefully move it past its retaining stops. The panel exposes the radio, alarm, lighter, front 12 V socket, interior lighting, optional amplifier and SW rear wiper fuses. The Peugeot handbooks keep the extraction tweezers and spare fuses in the glovebox.
Right side of dashboard, behind the glovebox: Open the passenger glovebox and release its fuse access cover. This is an independent electrical carrier, even though it has its own F3, F4 and F6 numbers. It protects the rear passenger and luggage 12 V sockets, electric windows, trailer electronics, audio amplifier and panoramic roof blind where installed. Right-hand-drive access uses different trim and should follow the matching owner handbook.
Engine compartment: Locate the protected fuse distribution box next to the 12 V battery. Release the lid catches, compare the physical labels with the appropriate year chart and replace only a fuse of the original rating. Press the cover firmly back into place to prevent moisture damage. Additional high-current links can be workshop-only and are not fully specified by the owner’s limited F20-F28 service table.
Model-year, body and equipment differences
The Peugeot 508 appeared in European showrooms in 2011 after its 2010 debut. A substantial 2014 facelift brought electrical and equipment changes, but the manufacturer retained core passenger-compartment circuit numbers. Both the 508 saloon and 508 SW use the F13 and F14 front outlets and independent glovebox-carrier F3/F4 rear outlets. However, left dashboard F30 (20 A) is the SW rear wiper and is not applicable to a saloon without rear wiping equipment. Behind the glovebox F15 (20 A) applies to the panoramic roof blind in appropriately equipped SW cars and to specified later non-hybrid RXH versions.
The early owner manuals list right main-beam engine F23 (15 A) and left main-beam F24 (15 A), plus F27/F28 5 A lamp shutter circuits. A digital transcription of the 2016 English handbook unusually gives F23 as 13 A; older original manufacturer tables consistently show 15 A, so use the original fitted fuse and vehicle-specific manual rather than applying an anomalous OCR value. Some late manuals omit F27/F28 from the owner-service summary; omission is not proof that their electrical circuitry was deleted.
Quick guide to the most requested 508 fuses
The eight entries below refer to three different physical fuse carriers. In particular cabin F6 A/B radio supply is not the same fuse as F6 30 A front window motors behind the glovebox.
| Pozycja | Amperaż [A] | Chroniony obwód / funkcja |
|---|---|---|
| F13 | 10 | Front cigarette lighter – left dashboard carrier F13 |

Lower-left dashboard fuse box
The factory audio system uses a 15 A fuse in F6 A or B and an alternative 15 A F28 A or B position according to the installed equipment. F8 (3 A) powers the alarm. F13 (10 A) is the front lighter, F14 (10 A) the separate front 12 V power socket. The roof console and mirror lights use F16/F17 (3 A), and F32 (10 A) supplies an optional Hi-Fi amplifier. F30 (20 A) is the rear windscreen wiper on SW estates with that consumer.
| Pozycja | Amperaż [A] | Chroniony obwód / funkcja |
|---|---|---|
| F6 A/B | 15 | Factory radio and audio system, fuse position A or B according to installed carrier |
| F8 | 3 | Factory alarm unit |
| F13 | 10 | Front cigarette lighter |
| F14 | 10 | Front 12 V accessory power socket |
| F16 | 3 | Rear courtesy lamps and rear map-reading lamps |
| F17 | 3 | Front courtesy lamp and illuminated vanity mirror |
| F28 A/B | 15 | Factory radio/audio system, alternative A or B location |
| F30 | 20 | Rear windscreen wiper on SW estate models only |
| F32 | 10 | Audio amplifier on equipped vehicles |
Second fuse box behind the passenger glovebox
F3 (15 A) protects the driver electric-window switch module and the rear passenger 12 V socket. F4 (15 A) serves the luggage-compartment outlet. F5 and F6 (30 A each) power the rear and front one-touch electric windows. F11 (20 A) is the trailer module and F12 (20 A) the Hi-Fi amplifier. F15 (20 A) is the optional panoramic glass-roof blind, especially in SW estates. F16 (5 A) is another driver window switch feed.
| Pozycja | Amperaż [A] | Chroniony obwód / funkcja |
|---|---|---|
| F3 | 15 | Driver-side window switch panel and rear passenger 12 V socket |
| F4 | 15 | 12 V accessory socket in luggage compartment |
| F5 | 30 | One-touch rear electric window motors |
| F6 | 30 | One-touch front electric window motors |
| F11 | 20 | Trailer towing electrical interface |
| F12 | 20 | Hi-Fi audio amplifier power supply |
| F15 | 20 | Motorised blind of the panoramic glass roof on SW and optional non-hybrid RXH; not fitted to every saloon |
| F16 | 5 | Driver-side electric-window switch panel |
Engine compartment F20-F28
The standard user handbook lists F20 (15 A) front and rear wash pumps, F21 (20 A) optional headlamp washers, F22 (15 A) the horn and F23/F24 (15 A each) the right and left main-beam headlamps. F27 and F28 each have 5 A for their respective left/right lamp mask/shutter circuits on the early documented configuration. Powertrain-dependent ECU and high-current circuits are not fully described in this short owner’s table.
| Pozycja | Amperaż [A] | Chroniony obwód / funkcja |
|---|---|---|
| F20 | 15 | Front and rear washer pumps |
| F21 | 20 | Headlamp wash system, when fitted |
| F22 | 15 | Horn |
| F23 | 15 | Right-hand main-beam headlamp |
| F24 | 15 | Left-hand main-beam headlamp |
| F27 | 5 | Left headlamp mask/shutter control |
| F28 | 5 | Right headlamp mask/shutter control |
Diagnosing typical Peugeot 508 electrical faults
Cigarette lighter does not work: Start at left-dashboard F13 (10 A). Front accessory socket dead: The socket has a separate F14 (10 A). Inspect each socket for damaged plugs or metal fragments before inserting a new fuse. Rear seat outlet: Behind-glovebox F3 (15 A). Luggage 12 V outlet: Behind-glovebox F4 (15 A). A working front socket does not mean the other three circuits have power.
Rear wiper in SW stopped: Left dashboard F30 (20 A), then inspect wiring where the tailgate opens. Front windows fail: Glovebox-side F6 (30 A) and door loom. Rear windows fail: F5 (30 A) in the same carrier. Horn silent: Engine F22 (15 A), then its relay and horn. Only the right high beam is out: Engine F23 (15 A); the left uses F24 (15 A). Panoramic shade stuck: Glovebox-side F15 (20 A) on a car actually fitted with that roof mechanism.
Related Peugeot 508 hybrid and estate versions
The Peugeot 508 RXH is the raised estate with hybrid and later diesel-only versions; its fuse table must be matched to the drive system and roof options. The 508 HYbrid4 has separate high-voltage powertrain components and requires specialist service. For the predecessor generation, see Peugeot 407 (2007-2011), whose fuse assignments do not carry over to the 508.
