Citroen has a history of innovation, from hydropneumatic suspension to front-wheel drive. Citroen shares platforms and engines with Peugeot, Opel/Vauxhall and DS within Stellantis. Citroen is part of the Stellantis group (formerly PSA Peugeot Citroen). On older Citroen HDi engines, Stage 1 goes in over OBD with no complications.
ECUs are standardised across Stellantis, so Citroen files often work on Peugeot/Opel/DS. The Citroen community in France and Western Europe has a large pool of Stage files. On naturally aspirated Citroen engines, the main effect is on throttle response. Low-output Citroen engines are city units, and Stage 1 is safe.
