Particulate matter sensor fault

[Buxton2901]

Hi guys, so my 2019 50tdi pinged up an engine management light on Saturday. Read the codes and it's U02A3 which is 'Lost Communication With Particulate Matter Sensor Module'

Has anyone else experienced this error? I'm presuming it's a bad dpf sensor.

Thanks
Paul

Morning Paul, Did you get any where with this?

I just picked up a 2019 50tdi last week and had the same fault come in this weekend.

Have you poked your head under the bonnet and looked to see if there is anything visibly wrong with the wiring and connections going from A to b. i.e. the sensor and your ECU?
