Known issues

• DPF (diesel particulate filter) clogging and regeneration problems, especially on low-mileage or urban-driven examples; can cost €800–€1,500 to clean or replace
• EGR valve carbon buildup causing rough idle, limp mode, and increased emissions; replacement €600–€1,000
• Injector deposits and fuel system coking on direct-injection diesel engines, leading to hard starting and performance loss
• Turbocharger bearing wear and oil starvation issues; replacement €1,200–€2,000
• AdBlue system faults (sensor malfunction, heater element failure) triggering warning lights and limp mode
• Timing chain tensioner rattle on cold start, particularly on higher-mileage examples; can indicate wear requiring replacement (€800–€1,200)
