BMW 5 Series2017

• Diesel 5 Series remains desirable for highway comfort and efficiency; strong demand evident in 33% year-on-year price rise and quick sales (32 days average).
• Mid-range asking prices fair given age and mileage; however, reliability score of 3/10 suggests significant maintenance risk — factor in potential €2,000–€4,000 repairs before purchase.
• DPF clogging, EGR carbon fouling, and injector stiction are common on this generation; urban-driven examples especially prone to forced regeneration costs and limp-mode faults.
• Before buying, request full service history and specifically ask if DPF has been professionally cleaned or replaced — avoid cars with gaps in diesel servicing records.
• Check for rough idle or hesitation on cold start; if present, EGR work may be imminent and could cost €800–€1,500 to rectify properly.
