Credov's researched list of the 7 faults the Land Rover Defender TDCi is known for (2007–2016), 5 of them serious or costly. Each one says what to look for when you check the car, so you can spot it before you buy. Not every car has these faults: they are the ones worth checking on this model.
What to look for: Before the test drive, idle in neutral and listen for a rattle that stops when the clutch pedal is pressed.
Why it matters: A rattling clutch plate is usually already breaking up and due for replacement, which on the Puma means removing the gearbox - a labour-heavy job. Buying the car without this check risks an unexpected clutch bill soon after purchase.
What to look for: On the drive, alternate gentle throttle and overrun then reverse, and listen for a heavy clunk from the middle of the car.
Why it matters: Clunks and backlash here point to spline wear between the gearbox and transfer box; left unchecked it progresses to a loss of drive. The shaft is a relatively cheap part, but diagnosis on a used car without history is harder and the fault can be mistaken for universal joint wear.
What to look for: Lie under the rear with a torch and tap the crossmember and outriggers for flaking scale or holes.
Why it matters: A badly rusted chassis means a full replacement frame or major bulkhead repair, both very large jobs, and freshly underseal-coated or repainted sections can hide rot rather than fix it. This is one of the biggest value risks on an older Defender and is common on New Zealand farm, beach and boat-launching vehicles.
What to look for: With the engine cold, check the expansion tank for froth or oil, and watch the temperature gauge on hills.
Why it matters: Left unaddressed the engine can overheat suddenly in traffic or on a hill, and because the same symptoms can also mean a head gasket fault, buying without testing risks a far bigger repair bill than expected.
What to look for: Watch for the DPF warning light at start-up and while driving, and ask whether the car mostly does short trips.
Why it matters: A blocked DPF that cannot regenerate normally can mean a professional clean or a new filter, and one owner was quoted several thousand pounds for a DPF and EGR replacement together. A removed or deleted DPF also leaves the car non-compliant and can hide the same underlying fault.
What to look for: Open every door and look along the bottom inside edge and the rear door seam for blistered paint or rust.
Why it matters: A door frame repair section or a replacement door and paint costs far more than catching it early with surface treatment and seam sealer, and visible corrosion hits resale on a car buyers pay a premium for.
What to look for: Lift the floor mats and press the front footwell carpets, and check the roof lining front corners for stains.
Why it matters: Most leaks are cheap to seal once found, but finding them takes time, and water left sitting under the carpet rusts the seat box and footwells and can reach wiring under the dash, turning a cheap fix into a bigger one if ignored.

On top of the faults above, every Credov inspection covers the basics: fuel smell, leaks or filler rust, engine oil leaks, power steering fluid leak, drive belt cracks or squeal, rust underneath: chassis and mounts, engine mounts, engine oil level and colour, coolant level, colour and leaks, head gasket failure signs, cold start: rattle, knock or smoke, rough or hunting idle, engine running hot on gauge, gearbox or diff oil leak, swapped gearbox without lvv and more.
