BMW 1 Series2018

• Diesel engines strong on fuel economy and torque, but watch for DPF clogging—especially critical if mileage sits below 80k km or car spent years in city driving. Budget €600–€1,200 for cleaning or replacement.
• Median price down 10% year-on-year; fair value against rivals, but inspect closely before committing. Market soft enough that negotiation room exists.
• EGR valve carbon build-up common around 80k–120k km; causes rough idle, power loss, and limp-mode. Injector wear also emerges at higher mileage—rough running and high fuel consumption are red flags.
• Request full service history and ask specifically about DPF regeneration cycles; book pre-purchase diagnostic scan to catch EGR or injector issues before you buy.
