Volkswagen Passat B8 (2014–2023) fuse box location and fuses
Updated:
The Volkswagen Passat B8 has 2 fuse boxes. The first is here: behind the storage compartment in the left part of the dashboard. Below we show where to find the fuses for the cigarette lighter, ABS, engine control unit, fuel pump, lights and wipers, and what to do if a fuse keeps blowing.
Always verify against the label on the box lid. Fuse layouts change with year and equipment.
Where the fuse boxes are
- 1Behind the storage compartment in the left part of the dashboard
- 2Engine bay, left side next to the battery, in a box with a lid
The diagram shows roughly where the boxes are, not the fuse layout.
Always check the lid or owner's manual: VAG changed fuse numbering by model year and equipment, so a 2005 and a 2008 car can differ.

Slot arrangement and shape are drawn from public fuse box diagrams (several sources agree); model year and equipment can differ, so check the lid. Colour shows the amp rating per ISO 8820. Grey hatched “?” = amps unconfirmed, no colour claimed. White slot = no data for it. R = relay.

The arrangement is schematic (number order) because no source confirms this box's physical layout. Only the fuses in the table are shown. Colour shows the amp rating per ISO 8820. Grey hatched “?” = amps unconfirmed, no colour claimed.
SB15: Second source lists the horn as no. 20 (10 A)

We compared public fuse tables and owner-manual extracts. An entry counts as confirmed when number and function match in at least two sources.
Common faults and fuses
Cigarette lighter / 12 V socket dead
Look for the socket or cigarette symbol, usually 15–20 A
ABS light on
ABS usually has two fuses: pump (large, 30–60 A) and control unit (5–15 A)
Related fault code: P0500
Engine won't start, dash lights on
The engine control unit (ECU) fuse and main relay are in the engine-bay box
Related fault code: P0606
Fuel pump silent at key-on
Look for the fuel pump symbol, usually 15–25 A, often with a relay
Related fault code: P0230
One headlight or tail light out
Bulb first, then fuse. On many cars a body control module drives the lights and there's no separate fuse
Wipers not working
The wiper fuse is large (20–30 A). If it's fine, the relay or motor is often to blame
How to check a fuse
Switch the ignition off and pull the fuse with the plastic puller. A blown fuse has a broken wire inside. Fit one of the same rating. If the new one blows straight away, there's a short in the wiring that needs diagnosing.
