The early Rover 75 (R40) uses a 42-position fuse panel behind the passenger glovebox and a separate 10-position fuse box in the engine compartment. This guide covers the original 1999-2002 electrical arrangement, including unoccupied positions and petrol/diesel differences. MG Rover revised the passenger fuse carrier in early 2003, so these diagrams must not be applied to later cars without checking the panel and VIN.
Fuse box locations and access
Passenger compartment: Switch off the ignition and open the passenger door. The main fuse panel is behind the glovebox, not next to the steering column. Locate the lower access cover, release its fastener with a coin or small flat-bladed screwdriver, remove the trim and press the two catches on the fuse-box cover. The numbered fuses are arranged as shown below.
Engine compartment: Open the bonnet. The engine fuse box is on the left-hand side of the engine bay when viewed in the direction of travel. Press the catch and hinge the cover open. Check the legend on your vehicle, particularly for the engine-specific positions. The separate high-current fusible links are not part of the ten numbered fuses in the table and are intended for service inspection.
Passenger compartment – fuses 1-42
The original 42-position layout is shown immediately above the complete table. Empty positions and the rated-but-unoccupied position 42 have not been omitted.

Engine compartment – fuses 1-10
The listed functions distinguish petrol and diesel applications. High-current fusible links housed separately from this block are not included in its ten numbered positions.

|---|---|---|
| 1 | 15 | Diesel: EGR, injection pump and fuel-pressure regulation; petrol: oxygen sensors; all engines: powertrain management |
| 2 | 20 | Petrol: ignition coils; all engines: engine management electronics |
| 3 | 15 | Petrol: camshaft sensor and oxygen sensors |
| 4 | 15 | Automatic transmission, air conditioning and cooling fan; diesel cruise control where fitted |

Practical checks for common electrical faults
In the early Rover 75, the cigarette lighter is protected by passenger-compartment fuse 15 (15 A), while the separate accessory outlet uses fuse 16 (20 A). If central locking is inoperative, check fuse 14 (20 A); the horn uses fuse 28 (15 A). The Tourer rear wiper has its own fuse 29 (15 A). A non-operating fuel pump points to cabin fuse 20 (20 A). If the engine cranks but does not start, the relevant engine-management feeds under the bonnet include positions 1, 2 and 5, depending on engine type. For failed front wipers, check engine-bay fuse 10 (30 A) and the BCU-related cabin fuse 5 (5 A).
Important fuse box changes from early 2003
In January 2003, MG Rover introduced a modular, hard-wired passenger fuse box using mini fuses. The wiring and fuse locations changed. In particular, the earlier 42-position layout is not a universal diagram for every Rover 75 built through 2005. Identify the actual panel and check the vehicle’s build date and VIN; the documented change is associated with VIN 279844 onwards.

The closely related MG ZT (2001-2002) fuse box guide covers the sporty model built on the same R40 architecture. The arrangement is similar in early cars, but engine and equipment variations still matter.
