P244A on Peugeot
Diesel Particulate Filter Differential Pressure Too Low (Bank 1)
P244A on Peugeot vehicles indicates diesel particulate filter differential pressure too low (bank 1). Au7o has documented this code across 2 Peugeot models — most commonly on 208, 3008. P244A is a diesel emissions code meaning the differential pressure across the diesel particulate filter (DPF) on bank 1 is too low. A pressure sensor measures the difference between the DPF inlet and outlet to gauge how loaded with soot the filter is; an abnormally low reading suggests the filter isn't restricting flow as expected. This can indicate a cracked, missing, or hollowed-out DPF substrate, or a sensor/hose problem giving a false low reading. It points to the DPF or its differential pressure sensing system rather than the engine itself. Typical repair costs on Peugeot range from $300 to $2,500, depending on the specific model and root cause.
Common Causes of P244A
- •Cracked, damaged, or failed (hollow) DPF substrate
- •Faulty DPF differential pressure sensor
- •Disconnected, cracked, or leaking pressure sensor hoses
- •Clogged or blocked pressure sensor reference lines
- •Exhaust leak upstream or around the DPF
- •Aftermarket or tampered/removed DPF
- •Wiring or connector fault at the pressure sensor
P244A on Peugeot by Model
Peugeot 208(1 issue)
- Diesel Particulate Filter Blockage2012-2026
Diesel 208 models suffer from premature DPF blockage, particularly in vehicles used predominantly for short urban journeys. The DPF cannot complete its regeneration cycle during short trips, leading to progressive soot buildup.
Peugeot 3008(1 issue)
- DPF Premature Blockage2009-2026
The 3008 diesel variants experience premature DPF clogging, with the larger vehicle weight and urban usage patterns contributing to incomplete regeneration cycles. The issue is more pronounced in pre-2017 models with the older DPF design.

What does P244A mean on Peugeot?▼
P244A stands for "Diesel Particulate Filter Differential Pressure Too Low (Bank 1)." P244A is a diesel emissions code meaning the differential pressure across the diesel particulate filter (DPF) on bank 1 is too low. A pressure sensor measures the difference between the DPF inlet and outlet to gauge how loaded with soot the filter is; an abnormally low reading suggests the filter isn't restricting flow as expected. This can indicate a cracked, missing, or hollowed-out DPF substrate, or a sensor/hose problem giving a false low reading. It points to the DPF or its differential pressure sensing system rather than the engine itself. On Peugeot specifically, this code is documented across 2 models.
What causes P244A on Peugeot vehicles?▼
Common causes on Peugeot: Cracked, damaged, or failed (hollow) DPF substrate, Faulty DPF differential pressure sensor, Disconnected, cracked, or leaking pressure sensor hoses, Clogged or blocked pressure sensor reference lines, Exhaust leak upstream or around the DPF. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P244A on a Peugeot?▼
Repair costs on Peugeot range from $300 to $2,500, depending on the specific model and root cause.
Which Peugeot models have P244A documented?▼
Au7o has documented P244A on 2 Peugeot models: 208, 3008.
