If the DPD warning light sensor switches on just seconds after turning the engine on, what could this mean?

A fault with the diesel particulate diffuser has been detected by the engine control module. You would need a diagnostic scan to retrieve the trouble codes to proceed further. It could be due to partial clogging of exhaust system or any leakages.

Retrieve the trouble codes and let us know what it is.
