Known issues and risks

Listed from most frequently reported, each with its source.

Oil consumption and lubrication problems

Often reported

Users report higher than normal oil consumption and related lubrication issues. This can lead to oil loss, rapidly dropping levels, and if not monitored, risk of accelerated wear.

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.
