Ok, so there are 2 things going on. One it is saying that your DPF additive fluid level is at the minimum and needs topping up. Secondly, it is saying that the particulate filter is at or near end of life.

So you will need to have the additive level topped up for sure and also consider whether you are going to deep clean or replace the DPF at some point. Be aware that both these actions will require action using Diagbox / Lexia to reset the additive counter when it is topped up and also when the DPF is cleaned or replaced, that the engine ECU is notified tha tthat the DPF has been replaced.

Fault Code:	P1445

Not sure what deleted your other post means but I appreciate the answers.If you are referring to “Service” light , this occurred at the same time as DPF additive low.

You created another post on another thread about the same thing

Yes it will do - the service light is usually put on with these types of warnings / messages, but you have the answers now.
