Is It Safe to Drive With a P244A Code?
Common Symptoms of a P244A Fault
DPF or EML warning light on
No always noticeable driveability issues
Possible failed regeneration attempts
Possible Causes of P244A
A P244A code can be triggered by faults in several different vehicle systems. Identifying the specific root cause requires proper diagnostic equipment and live data analysis — not just reading the code itself.
DPF Pressure Sensor Fault
The differential pressure sensor or its pipework has a fault.
DPF Sensor Pipe Blockage
Small pipes connecting the DPF pressure sensor are blocked with soot.
DPF Physical Damage
The filter has been damaged allowing exhaust to bypass it.
Wiring Fault
Electrical fault in the DPF pressure sensor circuit.
Why we don't list the exact part: A P244A code tells you what's happening but not why. Replacing parts based on the code alone without proper diagnosis is the most common way drivers waste money. A proper diagnosis identifies the exact cause first.

P244A and Your MOT
A stored P244A fault code will cause your car to fail its MOT. The engine management light will be illuminated during the test, which is an automatic failure under current MOT testing standards. Even if the light clears temporarily, the code remains in the ECU memory and can be read by the tester's equipment.
Get the fault properly diagnosed and repaired first — then have the code cleared and confirm the light doesn't return before booking your test.
