When a Boxer or Relay goes bang, it is rarely a small job. These are hard-working vans that cover serious miles, and when the engine finally lets go it tends to let go properly. If yours has failed, or a garage has told you it needs a new engine, here is what has usually happened and what it costs to get the van back on the road.
The Peugeot Boxer and Citroen Relay are essentially the same van under the badge, and they share the same 2.2 HDi engine, part of the PSA DW family. We fit these engines regularly, so this is familiar ground for us.
Why these engines fail
Most Boxer and Relay engine failures we see come down to one of a few causes, and high mileage is the common thread. These vans work for a living, often loaded, often on short delivery runs that are hard on an engine.
The usual culprits are turbo failure, which can send debris and oil through the system, oil pump and oil pressure problems that starve the engine of lubrication, timing issues, and plain wear on an engine that has covered big distances. Once one of these takes hold, the knock-on damage often reaches the bearings, the crank and beyond.
By the time the van is running badly or has stopped, the damage inside is usually extensive enough that a fresh engine is the sensible route rather than chasing individual faults through a worn-out unit.
These vans earn their keep for years. When the engine goes, a new one puts the whole van back to work rather than patching a tired one.
Warning signs worth catching early
An oil pressure warning light. Stop the van. Continuing to drive with low oil pressure turns a repairable problem into a new engine very quickly.
Blue or excessive smoke from the exhaust. Often a sign of turbo trouble or oil getting where it should not.
A knock or rattle from the engine, particularly from low down or under load.
Loss of power or the van going into limp mode.
Oil disappearing between services. Worth investigating rather than just topping up.
The earlier one of these is looked at, the more options you tend to have. Left to run, most of these faults end the same way.
Why a replacement usually makes sense
On a high-mileage working van, once the engine has suffered serious internal damage, a repair often means opening up an engine that has plenty of other wear waiting to surface. You fix one thing and the next follows.
A new engine resets that. You get a unit with no mileage and no history, which on a van you rely on for work is worth a great deal. It is the difference between putting the van back on the road for years and nursing a tired engine through a few more months.
Where a recondition is genuinely the better call, we will tell you, because we do that work too. But on these engines, at the mileage they usually reach us, a new engine is most often the stronger value over the life of the van.
What it costs
We supply and fit brand new 2.0 and 2.2 HDi engines for the Boxer and Relay from £5,500 plus VAT, on a fixed price rather than an open-ended estimate. Because we fit these engines regularly, we know exactly what the job involves and can give you a firm figure up front.
The same engine family covers a lot of ground beyond the Boxer and Relay, including the Peugeot Expert and Traveller, Citroen Dispatch, Vauxhall Vivaro, Fiat Scudo and Toyota Proace, so if you run any of those, this applies to you too.
It is always worth asking a cheaper quote exactly what engine is going in. A used engine from a scrapped van brings its own unknown history and mileage, and on a vehicle you depend on for work, that is a gamble a new engine avoids.
The downtime question
For a working van, time off the road is lost income, so it matters as much as the price. Because these are jobs we do often, we can give you a realistic timescale up front rather than a vague window, and get the van back to you as quickly as the work allows.
What to do next
If your Boxer, Relay or one of the related vans has a failed engine, or you have been quoted for a replacement, send us your registration. It tells us the exact engine variant, so we can come back with a fixed price quickly.
And if you are not sure whether a replacement is really needed, call us. We will give you an honest view of the damage and the best way forward, whichever way it falls.
