P244A on Skoda: How to Diagnose & Fix
Diesel Particulate Filter Differential Pressure Too Low (Bank 1)

P244A on Skoda by model: symptoms, diagnosis and fix
Same EGR cooler and DPF cluster as Octavia 2.0 TDI but more severely felt in Superb due to its motorway-heavy duty cycle. Post-Dieselgate emissions update accelerated DPF clogging in some cases. Failed EGR cooler can dump coolant into intake.
Common Symptoms
- White smoke from exhaust
- Coolant loss
- P0401/P0488 EGR codes
- DPF regeneration failure warnings
- Limp mode
How to Fix
EGR cooler replacement + DPF cleaning or replacement (€800-€2,500 total).
The 2.0 TDI diesels (Mk2 and Mk3) suffer DPF problems, especially on cars used mainly for short, low-speed urban trips that never allow the filter to complete a regeneration. Symptoms include a DPF warning, repeated/incomplete active regenerations, raised idle, and rising sump oil level (and falling fuel economy) because diesel from post-injection regen dilutes the engine oil. Owners report DPFs needing replacement at relatively low mileage (e.g. ~52,000 miles). Active regen contaminating the oil was specifically noted by dealers on Mk3 2.0 TDI cars.
Common Symptoms
- DPF warning light
- Repeated or incomplete regenerations
- Rising engine oil level / oil dilution
- Reduced fuel economy
- Raised or fluctuating idle
How to Fix
Take the car for a sustained motorway run at higher revs to complete a regeneration when the DPF light appears. If the filter is clogged, a forced regen via diagnostics or a professional DPF clean may recover it; otherwise replace the DPF. Change engine oil if it has been fuel-diluted by repeated regens, and choose a non-DPF/petrol/PHEV variant for short-trip use.

Frequently asked questions
What does P244A mean on a Skoda?
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 Skoda it is documented across 1 model: Superb.
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 Skoda?
Published repair estimates on Skoda range from $300 to $2,500 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.
