Particulate filter light, limp mode and oil level rising

2015 · Dacia Duster · 1.5 dCi 110 (K9K) · 120,000 km

P2463P0128

Root cause: Thermostat stuck partly open: the engine never got warm enough to finish a regeneration, so the filter loaded up and fuel from the interrupted regenerations diluted the oil.
