P246300 dpf soot mass high

 Diesel particulate filters remove about ninety percent of carbon particles (or soot) from a vehicle’s diesel exhaust. Most of these filters include a DPF housing that contains a filtrt. This filter traps large soot particles and lets exhaust gasses flow through and exit the vehicle through the tailpipe.

Soot particles can clog the DPF, which can increase exhaust back pressure. The powertrain control module (PCM) monitors exhaust pressure using a sensor.

Diesel Particulate Filter
Diesel particulate filters remove about ninety percent of carbon particles (or soot) from a vehicle’s diesel exhaust.

Once the PCM detects that your exhaust’s back pressure has exceeded a certain limit (the exhaust passes through the filter), it will trigger a regeneration procedure. The process involves incinerating the clogged particles and releasing them through the tailpipe.

However, if the PCM detects that the back pressure still fails to reach a certain limit, it will trigger the P2463 code and activate the check engine light.

VW p160300 Ctrl.module faulty

 Starting problam. If the engine stalls or fails to start while stop and start control is operating, DTC P160300 will be stored. Using the GTS, the freeze frame data recorded the moment the DTC is stored can be read. Serviceability has been enhanced by enabling the cause of an engine stall or engine start failure which occurred while stop and start control was operating to be checked using the freeze frame data. DTC No. Detection Item DTC Detection Condition Trouble Area Warning Indicate Memory Note P160300 Engine Stall History Both of the following conditions are met for 0.5 seconds or more (1 trip detection logic): Engine stopped by stop and start control and engine hood opened*1.
