Known Issues 3
DPF blockage — city driving
▸DPF warning light, loss of power, limp mode
DPF requires 20+ min highway driving at 60+ km/h to regenerate. Short city trips prevent regen.
CRITICAL: Athens city commute will CLOG the DPF within 30-40k km. NOT recommended for city-only Greek use. Choose B48 petrol instead.
EGR valve / cooler carbon fouling
▸Rough idle, smoke on startup, check engine light
Standard diesel EGR fouling. Worse with city-only driving.
Linked to DPF concern. City driving makes both issues occur simultaneously.
Timing chain tensioner (front-mounted)
▸Cold start rattle, check engine light
B47 fixed N47 by moving chain to front. Still needs attention at 120k+ km. Far cheaper to access.
Front-mounted = reasonable access for Greek mechanics. Monitor via cold start at each service.
