DPF clogging and forced regeneration

Attaches to dpf at component level · Emissions · carried by 206 variants across 106 chassis

Overview

DPF clogging and forced regeneration is a common fault recorded against dpf at component level, typically from 120–250k km. It shows up as warning light, limp mode, oil level rising above the maximum mark from fuel dilution. Where it's documented, the repair runs €250–€1,800 (forced regen or clean at the low end, replacement filter at the high end, costs dated 2026-07), and it can be partly checked before you buy. 206 variants across 106 chassis in this database inherit it.

What happens

Symptom. Warning light, limp mode, oil level rising above the maximum mark from fuel dilution.

Cause. The filter needs sustained hot running to regenerate. A car used for short urban trips never completes a regeneration cycle.

How to check it

OBD scan

Read the DPF soot load and the distance since the last regeneration on a scan tool, and check the engine oil level and smell it for diesel. Ask what the car was used for. A short-trip city diesel is the wrong car regardless of mileage.

Mandatory. A seller who refuses a scan has answered the question.
