Diesel Particulate Filter (DPF) Clogging
Often reported
On 1.5 diesel versions (A180d / OM607), especially with city driving or short trips, the particulate filter (FAP/DPF) may struggle to regenerate. Incomplete regeneration can trigger warning lights, power loss, and require intervention.
Exhaust Emissions
Exhaust Back Pressure / DPF Sensor Failure
Often reported
The exhaust back pressure sensor (DPF pressure sensor) can fail or become clogged with soot, causing DPF and exhaust pressure fault codes.
Exhaust Emissions
Oil Leaks and Smoke/Turbo Exhaust Circuit Contamination
Often reported
Some users report oil leaks from the turbo/gasket area or PCV system, causing oil to enter the exhaust circuit and stain the DPF. Oil burning can lead to smoke, odor, and accelerated soot buildup.
