Kia 1.6 CRDi 136 DCT
Euro 6 successor to the U2 diesel with SCR urea injection and revised DPF. More complex exhaust system demands attentive maintenance — top up AdBlue regularly.
Balanced compact diesel
136 hp Euro 6 diesel makes the Ceed CD a pleasant long-distance compact. Solid, quiet, efficient.
Engine Weaknesses 5
Like its predecessor the D4FB, the D4FE needs sufficient speed and engine load for active DPF regeneration. Short-trip use prevents complete regeneration cycles and causes blockage.
Symptoms: DPF warning, power reduction, increased fuel consumption, regeneration fails
Even on the newer D4FE (Euro 6), EGR cooler and valve eventually clog. A faulty EGR can increase consumption, worsen emissions and in rare cases cause cracks in the EGR cooler.
Symptoms: Judder at low rpm, EGR fault code, white smoke in cold weather (cooler crack)
The Euro 6 diesel D4FE is particularly prone to carbonisation of the EGR valve and EGR cooler at low load levels. Frequent short trips accelerate the process considerably.
Symptoms: Power loss, limp-home mode, judder at low rpm, fault code P0401/P0404.
The D4FE's particulate filter blocks up in frequent urban use. Due to the higher exhaust aftertreatment demanded by the Euro 6 standard, the DPF is more sensitive to incomplete regeneration cycles.
Symptoms: DPF warning light on, engine power dropping, increased consumption, limp-home mode possible.
Like its predecessor the D4FB, the D4FE is also prone to premature DMF fatigue in city traffic with frequent clutch use.
Symptoms: Vibration and rattling on pull-away and cold start, rough idle.
Vehicle Weaknesses 6
A design flaw in the tandem pump filter screen can interrupt oil supply and vacuum generation. An unexpected failure of the brake servo significantly increases stopping distances.
The Ceed CD's 7-speed dual-clutch gearbox exhibits judder and hesitation in cold conditions and city traffic. Particularly noticeable during gentle acceleration and manoeuvring.
The electric parking brake occasionally fails to release automatically when pulling away. Software updates have resolved the issue on most vehicles; remaining cases require mechanical intervention.
On the Kia Ceed CD the steering clicks when turning, especially at full lock. The cause is usually a worn rubber coupling on the EPS motor, which according to reports can become noticeable from as little as 25,000 km.
On the Kia Ceed CD SW, rumbling noises from the rear axle area are reported, particularly on uneven road surfaces. The cause is often rubber bushings of the torsion beam axle that have hardened over time.
Insufficient AC cooling performance is documented for the Kia Ceed CD — a technical service bulletin exists. The cause is usually low refrigerant or a faulty expansion valve.
