good morning

we present the case of an OPEL Corsa 1.3 CDTI with error p2453 Insufficient pressure difference particle filter pressure sensor

shows up at the workshop with key light on and glow plug light flashing

Problem Solution

after replacement of differential pressure sensor and hose check

it is necessary to regenerate on the road for at least 50/100 km until the filter is completely regenerated.

Otherwise, i.e. if the road test is NOT carried out, the warning lights will not go out.

good reading

Cordial greetings

Antonio
