Mercedes-Benz CLA2020

• Diesel engines demand strict servicing discipline—skip oil changes and you risk timing chain wear, DPF blockage, and EGR failure. Budget for preventative maintenance.
• Strong price recovery year-on-year signals solid demand, but €29k sits at upper end of market. Compare petrol variants and newer stock before committing.
• DPF regeneration faults are the key weak point on this engine. Confirm full service history and ask seller about any warning lights or forced regeneration patterns.
• Before purchase, request OBD scan for DPF and EGR fault codes—hidden issues often show up here even if warning lights are currently clear.
• On cold start, listen carefully for timing chain rattle. A quiet engine at -5°C is a good sign; any metallic noise warrants a mechanic's inspection.
