Depending on your regular driving routine (if more short + lower speed journeys) and the info shared here so far.
It's likely that your DPF and/or ERG are at least partially blocked, so, need to be removed and professionally cleaned (this has become common, as well as repeatable depending on the driving routine and mileage).
Also, if either were fully blocked you'd know about it as some have needed recovery for the same not allowing the engine to run.
Personally, I'd address this with a specialist sooner rather than later and hopefully, the existing parts are still reusable.
Of course, there is a more extreme school of thought on DPF and ERG systems that recommend having them removed completely.
Having experienced all of the above to various degrees over the years, I'm almost tempted to petrol even for higher mileage with a lot less to spectacularly fail (wink)
