Do Peugeot and Citroën use the same parts? Platform twins and where they differ

Peugeot and Citroën use the same parts through shared platforms

PSA engineered each platform once and built both brands on it. PF1 carries the small cars, PF2 the compact generation that began with the Peugeot 307 in 2001, EMP2 the compact and midsize cars and vans from 2013, and CMP the small cars since 2018. These are the pairs you meet most often:

• PF1: the Peugeot 207 (2006) and the first 208 (2012), with the Citroën C3 of 2009 and 2016 and the Citroën DS3.
• PF2: the Peugeot 307 with the first Citroën C4 (2004), and the first 308 and 3008 with the second C4 (2010) and the first C4 Picasso.
• EMP2: the Peugeot 308 of 2013 with the Citroën C4 Picasso of 2013, and the Peugeot 3008 of 2017 with the Citroën C5 Aircross.
• CMP: the Peugeot 208 and 2008 of 2019 with the Citroën C4 of 2020 and the DS 3 Crossback.

The 208 and the C3 went separate ways

Model names do not follow the platforms. The first 208 and the C3 of 2016 both sit on PF1. The second 208 moved to CMP in 2019, while the C3 stayed on PF1 until its 2024 replacement moved to the Smart Car platform.

So a 2021 Peugeot 208 has more in common underneath with a Citroën C4 than with a Citroën C3 of the same year. The 308 line has the same trap. The 308 of 2021 stayed on EMP2, while the Citroën C4 of 2020 went to CMP, so the two compacts stopped being twins.

Vans: Partner and Berlingo, Boxer and Jumper

The Peugeot Partner and the Citroën Berlingo have been twins since the first Berlingo of 1996. The second pair moved to PF2 in 2008, and the third, from 2018, sits on EMP2 and also wears Peugeot Rifter, Opel Combo, Toyota ProAce City and, from 2022, Fiat Doblò badges.

The large vans come from a different family. The Peugeot Boxer and the Citroën Jumper share the Fiat Ducato body, built by Sevel in Italy, so their parts cross to Fiat as well as between the two French brands. Our post on the Boxer and the Ducato covers that family.

Shared hardware, brand-specific bodywork

A shared platform means shared hardware under the skin: engines, gearboxes, suspension arms, brakes, cooling parts and much of the electrical system. A timing kit or a pair of brake discs for a Peugeot often carries the same number as the Citroën version, as long as the engine and the brake size match.

Anything the customer sees stays with the badge. Bumpers, grilles, headlights, tail lights, wings, doors and dashboard trim are drawn for one model and carry their own numbers. Even under the skin, two twins can differ in spring rates, wheel sizes and equipment, and those differences change the part in ways the model name does not show.

One numbering system in Service Box

Peugeot, Citroën and DS parts share one numbering system and one catalog. Service Box shows the same part number on a Peugeot VIN and a Citroën VIN when the part is common, so two lookups settle a crossover that a forum list can only suggest.

Check both VINs every time, since a number shared on one engine code does not carry over to another. On VINsearch, the Peugeot parts catalog and the Citroën parts catalog both run on Service Box, with DS alongside, behind one login.

Borrowing a part from the twin

If a Peugeot part is out of stock, the Citroën twin is the first place to look. Look up the part on your customer’s VIN and note the number, then check that number against the donor model. If the numbers match, it is the same part, whatever brand is printed on the box.

Used parts from a breaker need the same check with more care, because the donor car’s build matters as much as its brand. Our guide to part number interchange covers the wider method.
