Opel Insignia2016

• Diesel engine prone to DPF clogging on urban/low-mileage use; budget €800–€1,500 for potential cleaning or replacement.
• Injector sticking and carbon build-up common; causes rough idle and poor cold starts—have fuel system inspected pre-purchase.
• EGR valve carbon deposits can trigger limp-home mode; cleaning €400–€800. Request full service history proving regular oil changes.
• At €4,999 median, fair value for mileage and age, but reliability score is modest—factor in potential engine work costs.
• Before handover, request live OBD scan to check for DPF or EGR faults; drive test in mixed conditions for smooth idle.
