AI Market Summary

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.

Important caveats

NI import estimates assume the car is NI-registered (not GB-origin). GB-origin cars add customs duty (6.5%) + import VAT (23%), potentially €3,000–€6,000 more.
Revenue may assess a different OMSP than the ROI median shown above.
NOx levy for diesel can vary from €600 to €3,500+ depending on the vehicle's individual emissions figure.
Cars 4+ years old require an NCT before ROI registration.
Always verify the V5C registration history and get a quote from Revenue.ie before purchasing.
