P244A on Peugeot: How to Diagnose & Fix
Diesel Particulate Filter Differential Pressure Too Low (Bank 1)
1 Peugeot model · 1 documented issue · 1 critical · $300-$2,000 repair
P244A on Peugeot by model: symptoms, diagnosis and fix
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.
Common Symptoms
- DPF warning light
- Reduced engine power
- Increased fuel consumption
- Strong diesel smell
How to Fix
Perform a forced DPF regeneration using diagnostic equipment. For severely blocked filters, professional DPF cleaning or replacement is required. Advise regular motorway driving to allow passive regeneration.

Frequently asked questions
What does P244A mean on a 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 it is documented across 1 model: 208.
What are the most common causes of P244A?
The most common causes of P244A are: 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. The specific cause varies by vehicle.
How much does it cost to fix P244A on a Peugeot?
Published repair estimates on Peugeot range from $300 to $2,000 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
