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) reportedly struggles to regenerate. Incomplete regeneration can lead to warning lights, power loss, and the need for 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 Soot/Turbo Exhaust Circuit Contamination
Often reported
Some users report oil leaks from the turbo/gasket area or PCV system, leading to oil mixing into the exhaust circuit and staining the DPF. Oil burning can cause smoke, odor, and accelerated soot buildup.
