New Engine vs Reconditioned Engine: Why Brand New DV5, DW10, DW12 and EcoBlue Engines Last Longer

What a reconditioned engine really is

A reconditioned (or rebuilt) engine starts life as a used engine. It is stripped, cleaned, and any visibly worn or damaged parts are replaced before it goes back together. The quality of the result depends entirely on who did the work, which parts they replaced, and which ones they decided were "good enough" to reuse.

That last point matters. In many reconditioned DV5, DW10 or DV6 engines, major components — the crankshaft, cylinder head casting, pistons and timing components — are original used parts with unknown history. Even a well-rebuilt engine is a mixture of new parts and old metal that has already endured years of heat cycles and stress.

Longevity: new metal versus reused metal

A brand new, zero-hours engine starts every component at zero wear. On our new DV5 1.5 BlueHDi, DW10 2.0 BlueHDi, DW12 2.2 BlueHDi, DV6 1.6 HDi and Ford EcoBlue engines, every bearing, piston ring, bore, valve, camshaft and timing chain is new and machined to original manufacturer specification. The engine delivers its full design life from day one — exactly as Peugeot, Citroën, Fiat and Ford intended.

A reconditioned engine can never reset the clock on the parts that were reused. A crankshaft with 120,000 miles of fatigue behind it still has 120,000 miles of fatigue after a rebuild. This is why rebuilt engines carry a meaningful risk of early failure that a brand new engine simply does not.

For a working vehicle — a Ford Transit, Citroën Relay, Peugeot Boxer or Fiat Ducato that earns its keep every day — downtime is the hidden cost. A second engine failure six months after a cheap rebuild can cost more in lost work, recovery and labour than a new engine would have cost in the first place.

Warranty: where new engines win outright

Warranty is the clearest signal of how much confidence a supplier has in their own product. Reconditioned and rebuilt engines are commonly sold with 3 to 6 month warranties, often with mileage caps or strict conditions that make claiming difficult. Used or salvage engines may come with 30 to 90 days — or nothing meaningful at all.

Every brand new engine we supply — DV5, DW10, DW12, DV6, 1.5 EcoBlue (LXD) and 2.0 EcoBlue — comes with a 12-month, unlimited-mileage warranty. Whether you cover 5,000 miles or 50,000 miles in that year, you are covered. That is only possible because every part is new: we know exactly what is inside the engine, because none of it has ever been used before.

• Brand new engine (DV5, DW10, DW12, DV6, EcoBlue): 12 months, unlimited mileage
• Typical reconditioned engine: often 3–6 months, frequently with mileage limits
• Used or salvage engine: often 30–90 days, or no real warranty at all

The exchange surcharge: how it works

Our brand new engines are sold on an exchange basis: a refundable £350 surcharge applies and is returned to you once your old engine comes back to us. This keeps the process simple and ensures your old unit is disposed of responsibly.

With a reconditioned engine you are often paying a surcharge against someone else's unknown core — and if your old engine is judged unsuitable, you may lose the surcharge entirely.

Total cost of ownership: new engines usually win

On paper a reconditioned engine is cheaper. In practice you should add up the full picture: the shorter warranty, the higher risk of repeat failure, the labour cost of fitting an engine twice, and the downtime while your van is off the road. Fitting a replacement diesel engine is a significant job — most owners only want to do it once.

A brand new crate engine fitted once, covered for a full year with no mileage limit, is very often the cheaper outcome over two to three years of ownership — whether it's a DV5 for a Peugeot 308, a DW12 for a Citroën Relay, a DV6 for a Berlingo or a 2.0 EcoBlue for a Ford Ranger.
