The Volkswagen Transporter T5 was produced from 2003 to 2009 before the facelift. This generation was also sold in different passenger and commercial versions, including the Transporter, Caravelle, Multivan and California.

In this guide, you will find the Volkswagen Transporter T5 fuse box diagram, fuse locations, fuse assignments and information about the main passenger compartment and engine compartment fuse boxes.

You can also use the interactive fuse diagram below. Click or tap any fuse to see what it protects.

Important: Fuse assignments can vary depending on the production year, engine, transmission and vehicle equipment.

Where are the fuses located in the VW T5?

The Volkswagen Transporter T5 uses several fuse panels.

The main fuse holders are located:

  • inside the passenger compartment;
  • underneath the dashboard;
  • around the lower dashboard / centre electrical area;
  • in the engine compartment;
  • near the battery for high-current fuses;
  • under or near the driver’s seat on some versions.

Some Multivan and California models may have additional fuses for auxiliary batteries, heating, camper equipment and 12V sockets.

VW T5 cigarette lighter fuse

The main cigarette lighter in the Volkswagen Transporter T5 is protected by:

SB12 – 15A

If the cigarette lighter has stopped working, check Fuse SB12 first.

However, the T5 can have several 12V sockets. Depending on the model and equipment, additional sockets may use fuses in the SC fuse panel.

For example, some versions use:

  • SC1 – auxiliary 12V socket on early models;
  • SC7 – 12V socket on some 2005–2009 vehicles;
  • SC26 – 12V socket 2 on some Multivan models;
  • SC34 – 12V socket 3 on later versions.

Therefore, if one socket works but another does not, check the appropriate auxiliary socket fuse rather than SB12 only.

Fuse Holder C – SC fuses

Fuse Holder C contains many optional and comfort equipment circuits.

VW T5 engine compartment fuse box

Another fuse holder, designated SD, is located in the engine compartment.

This block protects important engine management, ABS, transmission, cooling and fuel-system circuits.

High-current fuses

The Volkswagen T5 also uses high-current fuses near the battery.

The main alternator fuse can have a rating of:

150A, 175A, 200A or 225A, depending on the vehicle specification.

Other high-current circuits can supply:

  • power windows;
  • heated rear window;
  • main electrical system;
  • auxiliary battery;
  • heater systems.

Common VW T5 fuse locations

If you are looking for a specific electrical problem, these are some of the most useful fuses to check:

Cigarette lighter: SB12 – 15A
Left dipped beam: SB5 – 15A
Left high beam: SB6 – 15A
Right dipped beam: SB27 – 15A
Right high beam: SB28 – 15A
Rear wiper: SB30 – 10A
Horn: SB31 – 30A
Windscreen wiper motor: SB32 – 25A
Radio/navigation: SB33 – 15A
Turn signals: SB36 – 25A
Fog lights: SC27 – 15A
Heated mirrors: SC20 – 10A
Heated seats: SC25
Parking sensors: SC8 – 5A

Fuse keeps blowing – what should you check?

If a replacement fuse blows again, do not replace it with a fuse of a higher amperage.

Check the circuit for:

  • damaged wiring;
  • short circuits;
  • corrosion;
  • damaged sockets;
  • faulty electric motors;
  • aftermarket radios;
  • trailer wiring;
  • alarms;
  • additional lighting;
  • damaged 12V accessories.

A repeatedly blown fuse usually indicates an electrical fault somewhere in the protected circuit.

Conclusion

The Volkswagen Transporter T5 2003–2009 uses several fuse panels identified as SB, SC and SD.

The most commonly searched fuse is the cigarette lighter fuse:

SB12 – 15A

Additional 12V sockets can use separate SC-series fuses, so always determine which socket has stopped working before replacing a fuse.

Because fuse assignments can differ according to year, engine and equipment, compare the diagram with your specific Volkswagen Transporter, Caravelle, Multivan or California.
