P2463 DPF restriction - soot accumulation (bank 1)
P2463 means too much soot has built up in the DPF and it is restricting the exhaust gas flow. The exact definition of the code can differ between makes, so we assess it together with the other codes and the sensor data. If the ceramic is intact, the filter can usually be restored.
Does restoration help?
Most likely restorable
Often yes. If the filter is clogged with soot or ash and the ceramic is intact, professional cleaning can restore the flow - ash does not burn off during regeneration. Before cleaning we check the sensor and pipes and fix the cause of the clogging; a measurement before and after confirms the result.
A code shows where to look, but it is not a final diagnosis. We make the decision at the workshop after diagnostics and measurement.
Symptoms
- DPF or Check Engine light on.
- Reduced power, limp mode, higher fuel consumption.
- Regeneration does not complete, especially on short trips in town.
Most common causes
- Soot build-up after incomplete regenerations.
- Ash in the filter, which does not burn off during regeneration.
- The engine produces too much soot - for example, injector or EGR problems.
- A pressure sensor or pipe fault.
Order of checks
What to do
- 1
Sensor and pipes
We check the differential pressure sensor and its pipes - a wrong signal can look like a clogged filter.
- 2
Forced regeneration
If the filter holds mainly soot, we try a forced regeneration with diagnostic equipment.
- 3
Cleaning and measurement
If regeneration does not help or there is ash in the filter, we remove it and clean it in an OTOMATIC machine. We check the flow before and after.
FAQ
Questions about P2463
P244B reports too high a pressure difference, P2463 reports soot build-up. Both usually point to a clogged filter, and the order of checks is the same: sensor and pipes, regeneration, then cleaning.
If you keep driving with a clogged filter for a long time, power drops and fuel consumption rises. If the car goes into limp mode, drive as little as possible and go to a workshop.

Tick the symptoms or enter the fault code - in 30 seconds you get a first assessment of whether the part can be restored. If restoring is no longer worth it, we buy the old converter.
