BMW 5 Series2018

• Timing chain rattle on N20/N26 engines common—listen for cold-start noise; replacement costs €1,800–€2,500 if needed.
• High-pressure fuel pump failures typical around 80k km; check for starting hesitation or limp-mode warning lights during test drive.
• iDrive infotainment prone to freezing and unresponsiveness—test all functions (navigation, climate menus, touchscreen responsiveness) thoroughly before purchase.
• Median mileage sits within expected range for age; pricing is fair but watch for any timing chain history in service records.
• Always obtain full BMW service history and ask dealer/seller directly if timing chain, fuel pump, or iDrive work has been done.
