BMW 6 Series2018

• Diesel 6 Series offers executive comfort and strong motorway performance, but this engine demands meticulous service history and highway miles to avoid expensive failures.
• Median asking price sits fair for the market segment; verify any sub-€30k examples have full documentation—suspiciously low prices often hide DPF or turbo damage.
• DPF regeneration faults are the critical issue on this model. Short urban trips clog the filter; check service records for regular motorway use and successful regenerations, not repeated limp-mode warnings.
• Turbocharger and fuel injectors deteriorate if oil changes are missed. Request complete dealer service history (not independent stamps alone) and have a BMW-specialist pre-purchase diagnostic scan before committing.
• Inspect the most recent NCT certificate for emissions pass or advisories; a failed DPF regen cycle often triggers MOT-equivalent issues and signals imminent €1,500+ repair bills.
