- Sedan and wagon practicality
- Straightforward mechanical design
Cons
- Age-related corrosion and wear
- Significant engine and equipment variation
- Some trim and electrical parts may be difficult to source
Common problems & ownership concerns
Potential impact: Low · Medium · High. This describes possible consequences, not fault likelihood.
- Body corrosionHigh
- Suspension and steering wearMedium

Engine overview · 2.5L 4-cyl DIESEL
A potentially durable older diesel, but non-turbo and turbocharged 505 applications need separate assessment. Current cooling, fuel-system and lubrication condition is more important than the catalogue label.
Pros
- Simple diesel servicing on many versions
- Good long-distance suitability when maintained
Cons
- Age-related condition varies widely
- Turbo versions need more careful cooling and lubrication maintenance
- Cold-start systems can be costly to refresh
Common problems & ownership concerns
Potential impact: Low · Medium · High. This describes possible consequences, not fault likelihood.
- Cooling-system condition on all 2.5-litre diesel applicationsHigh
- Fuel-injection and cold-start wear on all applicationsMedium
- Turbocharger and boost plumbing on turbocharged applications onlyMedium
- Oil leaks and lubrication-system neglect on all applicationsMedium
Maintenance
Follow the confirmed engine code’s manual-specific schedule, using the specified diesel oil and maintaining filters, cooling components and—on turbo versions—lubrication carefully.
These are general ownership concerns, not a diagnosis. Equipment and engine details vary by version and production date.
