Engine Internal
Diesel Particulate Filter (DPF) clogging
Often reported
The 1.5 dCi engine used in city cars may experience incomplete regeneration and soot buildup in the DPF, especially on short trips or city driving, because it cannot easily reach the operating temperature required for regeneration.
Exhaust Emissions
Common rail injectors prone to failure
Often reported
Injectors in the 1.5 dCi engine (code K9K) are among the most reported issues. They can fail even at not very high mileage, causing power loss, misfiring, black smoke from the exhaust, and abnormal fuel consumption.
