P2463: Diesel particulate filter restriction: soot accumulation
The diesel particulate filter holds more soot than it should and has not been cleaned in time. Short trips or failed regenerations are typical causes.
| Code | P2463 |
|---|---|
| System | Engine and transmission |
| Group | P24xx, EGR, EVAP and particulate filter |
| Type | Generic: it means the same on every make |
| Can you keep driving? | With care |
What P2463 means
The particulate filter traps diesel soot and burns it off now and then in a regeneration. The ECU estimates it is now overloaded, usually because regenerations have not been able to finish. If it fills too far, it may no longer be allowed to regenerate automatically.
Most common causes
- Lots of short trips that never let regenerations finish
- Differential pressure sensor or its pipes giving wrong readings
- Faulty exhaust temperature sensor preventing regeneration
- Engine producing excess soot: injector, EGR or intake leak
- Another stored fault code that blocks regeneration
Symptoms
- Engine or DPF warning light on
- Loss of power or limp mode
- Higher fuel consumption
- Fan keeps running after switching off
Can you drive with P2463?
With care You can drive with care, but deal with it soon. If the filter keeps filling, a forced regeneration at the garage becomes riskier and may end in the filter being cleaned or replaced.

How to check it
Check the estimated soot load on your scanner and look for any other stored codes: fixing those first often unlocks regeneration. If the load is not extreme, a steady motorway run may be enough.
How to read and clear P2463 with Final OBD
Plug an OBD2 scanner in under the steering wheel, switch the ignition on and open Final OBD. Under Faults you’ll see P2463 with its description and whether it’s confirmed, pending or permanent.
If the engine stores it over standard OBD, with FREE you read this code with its explanation for nothing and clear it. With PRO you also read the faults of every control unit and clear them in all of them.
Clearing the code only turns the light off: if the cause is still there, it comes back. Clear it once it’s fixed, and not right before an inspection. It’s all in how to read and clear fault codes and in inspections and OBD.

How do you clear P2463?
With an OBD2 scanner and an app like Final OBD, which clears it for free if it’s stored by the engine control unit. But clearing it only turns the light off: if the cause isn’t fixed, P2463 comes back.
Read it on your car
Final OBD reads and clears engine faults through standard OBD for free, each one explained in plain English. With PRO it also reads the faults of every control unit, each make’s own codes included, and clears them in all of them.
