Recall, TSB, and manufacturer communication notes
NHTSA recall research for the 1984 Peugeot 505 identified one recall record:
- Campaign 84V151000: Related to the fuel system (gasoline storage tank assembly filler pipe and cap). The fuel caps may not seal properly, which can cause the gasket to swell and prevent adequate sealing. A replacement cap was provided as a remedy.
Note: This research is based on available NHTSA data. Owners should always verify current open recalls by checking their specific VIN through official manufacturer or NHTSA channels.
About this vehicle
The 1984 Peugeot 505 represents a significant era in Peugeot’s history, serving as the manufacturer’s final rear-wheel drive model. Produced between 1979 and 1992, the 505 was designed as a large family car built for durability and long-distance comfort. While production occurred primarily in Sochaux, France, it also saw international manufacturing in markets such as Argentina, China, Thailand, Indonesia, and Nigeria.
This specific model features a 2.3L 4-cylinder diesel turbo engine. Peugeot utilized various diesel engines across their lineup during this period, such as the XUD series found in other models. Owners of these vintage diesel units should focus on maintaining the turbocharger integrity and fuel injection systems, which are critical for performance in older turbocharged diesel applications.
From a maintenance perspective, owners of this classic Peugeot should pay close attention to its rear-wheel drive configuration and potential transmission requirements. While ZF produced 4-speed automatic transmissions (such as the 4HP family) used in various passenger cars during this era, the specific transmission pairing for this 1984 diesel model should be confirmed via the vehicle’s VIN or owner’s manual.
