DW10 Engine: Which Peugeot, Citroën & Vauxhall Models It Fits

What is the DW10 engine?

The DW10 is a 2.0 litre four-cylinder diesel engine family developed by the PSA Group, the French manufacturer behind Peugeot and Citroen. It has been one of the most widely used diesel engines in Europe for two decades, powering everything from family cars and MPVs to the vans that keep half the UK's trades on the road. If you drive a Peugeot Expert, a Citroen Dispatch or Relay, a newer Vauxhall Vivaro, or a Toyota ProAce, there is a good chance a DW10 sits under the bonnet.

You will rarely see "DW10" on the brochure. On the vehicle itself the engine is badged HDi on earlier models and BlueHDi on later ones, usually with a power figure alongside, such as BlueHDi 120. DW10 is the engineering family name, and the code that identifies your exact engine is stamped on the block and recorded against your vehicle.

HDi and BlueHDi: the same family, two generations

HDi stands for high-pressure direct injection, the common-rail fuel system PSA rolled out across its diesel range. BlueHDi is the later generation of the same family, updated to meet Euro 6 emissions rules. The headline change is the addition of AdBlue injection and a more sophisticated exhaust after-treatment system, alongside revisions to the engine itself.

For a replacement engine, the distinction matters. An HDi era DW10 and a BlueHDi era DW10 are different builds with different ancillaries, sensors and emissions equipment, so one cannot simply stand in for the other. Even within the BlueHDi generation there are several distinct variants. That is why the suffix letters are so important.

Why the suffix letters matter

Every DW10 carries a suffix, such as DW10CD, DW10FE or DW10FDDU. Those letters identify the precise specification: the power output, the emissions standard, the injection hardware and the vehicles the unit was built for. Alongside the DW10 code, each variant also has a shorter engine code, such as AHZ, AHK or EHT, which is what you will usually find on the V5C logbook and stamped on the block.

Variants are not interchangeable. A DW10FE from a 2018 Dispatch will not drop into a Boxer that left the factory with a DW10FUD, even though both are 2.0 BlueHDi diesels. Mountings, ancillaries, wiring and emissions equipment all differ. Ordering by the exact code is the only safe way to buy, which is why we confirm every order against the registration or VIN before it ships.

DW10 variants and the models they fit

Here are the DW10 variants we regularly supply as reconditioned engines, with the models and years they were fitted to:

If your engine code is not in the table, that does not mean we cannot help. Stock changes regularly and we can often source variants that are not listed, so get in touch with your registration and code.

Why do Vauxhall vans have a Peugeot engine?

It surprises plenty of owners to find a French engine code in a Vauxhall. The explanation is simple: Vauxhall became part of the PSA Group in 2017, and its vans moved onto shared platforms soon after. The current Vauxhall Vivaro is built on the same underpinnings as the Peugeot Expert and Citroen Dispatch, and the Combo shares its bones with the Berlingo and Partner. Sharing the platform means sharing the engines, so a Vivaro of this era runs the same DW10 BlueHDi units as its Peugeot and Citroen siblings, and the Toyota ProAce joins the family through a separate partnership on the same van.

For you as an owner this is actually good news. Because one engine serves several badges, reconditioned supply is stronger and parts are easier to come by than for an engine used in a single model.

How to confirm which DW10 you have

Never order by model and year alone. The same van in the same year could have left the factory with more than one DW10 variant, and the differences are enough to stop a mismatched engine from ever running properly. Confirm the exact code first:

• Check your V5C logbook. The engine number in section 4 usually contains or matches the engine code.
• Look at the block. The code is stamped on a machined surface on the engine itself, though it can be hidden under grime.
• Use your VIN. The 17-character VIN ties the engine specification to your exact vehicle.
• Send us your reg. Enter your registration on our homepage and send it straight to our team, and we will confirm the exact engine for your vehicle, usually the same day.

Our guide on how to find your engine code walks through each method in more detail.

Reconditioned DW10 engines from Engine Hub

We supply reconditioned DW10 engines across the HDi and BlueHDi range, covering the Peugeot, Citroen, Vauxhall and Toyota applications in the table above. Every engine is stripped, inspected and rebuilt with worn components replaced, then supplied with a 6-month warranty as standard on an exchange basis, which simply means your old unit comes back to us. You can read about the process on our reconditioning page, or browse the Peugeot, Citroen and Vauxhall collections to see current stock and prices.
