Mercedes-Benz E-Class2016

• Diesel engine robust overall, but injector carbon build-up and rough idle common — OM651 engines particularly vulnerable; budget for preventative cleaning.
• DPF clogging is major risk on this age/mileage, especially if previous owner did short urban trips; inspect service history for regeneration warnings and cleaning records.
• Turbocharger wastegate wear reduces power after 100k km; listen for turbo lag or loss of responsiveness during test drive, check boost gauge if available.
• Median price €15,999 sits fair for market supply and age; verify full Mercedes service history and emissions test pass before committing — skipped services inflate risk.
• Check last two NCT certificates for emissions failures or advisories; DPF and turbo issues often flag here first and cost serious money to remedy post-purchase.
