BMW 7 Series2017

• Excellent comfort, refinement, and commanding presence on Irish roads; strong six-cylinder diesel when healthy.
• Mid-market pricing reflects age and known diesel-emission complexity — not undervalued, fair for condition.
• N57 diesel engines prone to carbon accumulation and DPF faults, especially on inconsistent-mileage cars; AdBlue sensor failures common and expensive.
• Before purchase, request full BMW service history and latest emissions-test results; budget €800–€1,500 for potential DPF cleaning or replacement.
• Electronic parking brake and brake callipers fail unexpectedly on this generation — inspect braking system carefully during test drive.
