Common questions

Using this guide.

What are the common faults with the Land Rover Defender 2.5 TD5?

Garages and workshops regularly encounter 14 documented faults on the Land Rover Defender 2.5 TD5 — four concern the engine and fuel system and four the brakes. Each fault above lists the symptoms, cause, fix and any parts needed.

Does every Land Rover Defender 2.5 TD5 have these faults?

No. These are patterns documented across the model by workshops, not predictions for an individual car. Where a fault applies only to certain vehicles or VIN ranges, that is listed with the fault.

Can I check for Land Rover Defender 2.5 TD5 faults when viewing one?

Many of them, yes — the documented symptoms are things you can see, hear or feel on a viewing or test drive. The 'Before you view one' checklist above turns each documented fault into a quick check you can tick off as you go.
