P24C6 - Manufacturer-specific code

[Gecko_Bioyag77]

Hi, hoping that someone has some advice on an engine warning light which came on this evening for my T6.1 California MY23, a 204hp DSG. I restarted the the engine to see if it cleared but it’s still there so going to contact VW garage in the morning as its still under warranty. I ran a scan using Carista to identify the engine fault issue/error, it seems to be a P24C6 sensor / circuit that has failed, see info below which appears to be the Particulate Matter Sensor. Hopefully this is straightforward replacement as the van has only recently been serviced and I had the 6oK DSG transmission oil change too, however VW updated the ECU software when it was in the garage I so hope the engine fault issue is unrelated. I assume the van should not be driven, even though it is not currently in limp mode and seems to be running fine other than the warning light.

Thanks,
Graham
