Diesel particulate filter (DPF)

P2464 DPF differential pressure: too low (bank 2)

By: · Updated:

P2464 means: DPF differential pressure: too low (bank 2). The diesel particulate filter (DPF) traps soot and burns it off from time to time. Drive gently and have the car checked soon. The repair usually costs about €80–1500 in Estonia. The most common cause: lots of short trips so regeneration never finishes.

What it means

The diesel particulate filter (DPF) traps soot and burns it off from time to time. The filter is blocked, regeneration fails, or the filter sensor reading is wrong. Bank 2 is the side of a V engine without cylinder 1.

What you may notice

  • DPF or engine light on
  • Less power or limp mode
  • Higher fuel consumption
  • Fan running after switch-off

What could be wrong

  1. 1Lots of short trips so regeneration never finishes
  2. 2DPF pressure sensor or its hoses
  3. 3Injectors or EGR making too much soot
  4. 4Filter full of ash (high mileage)

Repair difficulty: Moderate

What you can check yourself

If the DPF light is on, drive steadily on the open road for 20–30 minutes so regeneration can finish. Best left to a workshop. It needs a diagnostic tool and experience.

How we fix it

  1. We read soot load and the pressure sensor
  2. We run a forced regeneration with the diagnostic tool
  3. We fix the cause of excess soot
  4. We clean or replace the filter

Want a definite answer?

Bring the car to our workshop in Estonia for diagnostics. We read the fault codes, test the sensors and tell you what is wrong. Repair price depends on the work involved, generally €45 per hour.

Questions

What does fault code P2464 mean?

DPF differential pressure: too low (bank 2). The diesel particulate filter (DPF) traps soot and burns it off from time to time. The filter is blocked, regeneration fails, or the filter sensor reading is wrong. Bank 2 is the side of a V engine without cylinder 1.

Can I drive with code P2464?

Drive gently and have the car checked soon.

How much does it cost to fix P2464?

Roughly €80–1500 in Estonia. The price depends on exactly what has failed and on the car.

How is P2464 fixed?
