BMW 320 320d 2003

🚨 What to check before buying

Overall risk score: 10/10

Serious risks

• Swirl flap failure (M47TU2): Intake swirl flaps can break and be ingested into engine. Delete is recommended.
• EGR clogging: EGR clogs with carbon, especially city driving.
• Turbo failure (high mileage): Original turbo can fail above 200k km. Replacement is straightforward.
• Car is 23 years old — expect age-related wear: rubber seals, bushings, water pump, AC compressor
• Very high mileage (293,024 km) — expect suspension, drivetrain, and turbo wear. Thorough pre-purchase inspection essential.

Additional notes

• Older BMW with 200k+ km will likely need suspension refresh (control arms, bushings: €600-1,200), possibly cooling system components (water pump, thermostat: €300-700), and various sensor replacements. Budget accordingly.
• Pre-2010 diesel with 250k+ km: injectors, turbo, EGR all at end of life. DPF regeneration failures cause cascading damage. Total repair bill can easily exceed car value. Budget €2,000-5,000 for major overhaul. Consider whether the car is worth investing in.
• Vehicle is 15+ years old. Age-related issues: rubber seals/hoses degrade, electrical connectors corrode, suspension bushings wear. Not specific to any engine, but expect €500-1,500/year in age-related maintenance beyond normal service items.
• Any car with 200k+ km requires extra scrutiny. At this mileage: suspension components are worn (bushings, ball joints, shocks), seals and gaskets are hardened, electrical connectors corrode, and major components approach end-of-life. For luxury cars (BMW, Mercedes, Audi) the cost of 200k+ km maintenance can exceed the car's value. Always get a pre-purchase inspection (PPI) and budget 15-25% of purchase price for immediate maintenance.
