The Citroen range covers compacts, saloons, SUVs, MPVs and commercial vehicles. HDi and BlueHDi are Citroen's badges for direct-injection turbo diesels.
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.
