The Citroën Relay — known as the Citroën Jumper in continental Europe — shares its platform, chassis and engine family with the Fiat Ducato and Peugeot Boxer. All three are built on the same Stellantis architecture, meaning a Relay motorhome uses the same proven diesel powertrain and responds identically to ECU calibration.
While fewer UK motorhomes carry the Citroën badge compared to the Ducato, those that do benefit from exactly the same calibration expertise. The engines are functionally identical; only the branding and some trim details differ between the three variants of this shared platform.
We support all Citroën Relay (Jumper) generations from the original 2.0 HDI through to the current 2.2 BlueHDI, covering the complete power range from 84 to 180 BHP. Our vehicle database lists these under the European 'Jumper' model name — the underlying data and calibration are identical.
Engine Range
The Relay uses PSA/Stellantis HDI and BlueHDI diesel engines from 2.0 to 3.0 litres across four generations. These are the same engines found in the Fiat Ducato and Peugeot Boxer under different designations. Power outputs range from 84 to 180 BHP.
