Emissions-system and fuel-system upkeep (2018–2021)
MinorLike other modern diesels, the 3.0 relies on a particulate filter, SCR with DEF and a high-pressure common-rail pump. Short-trip use increases filter regenerations, and contaminated fuel or overdue filters put the high-pressure pump and injectors at risk.[1][2]
Symptoms
- DEF or emissions warning messages
- Frequent regeneration
- Reduced-power mode
Check before buying
- Ask for fuel-filter and oil-service records
- Scan for stored emissions codes
- Confirm no emissions equipment has been removed
