Ok, what is your current mileage??

Your car requires an EOLYS top up every 37,500 miles and a complete DPF change every 75,000 miles. This is why I'm asking your current mileage.

If the DPF is not changed at the correct interval (75,000) then depending on driving and conditions you are likely to get another 20k miles or so before getting complete blockage problems which I suspect you are now experiencing.

You can get the complete blockage problems also though if the EOLYS fluid is not topped up as it is the EOLYS fluid that is injected and used to bring the temperature up high enough as part of the regen process and burn off the particles caught by the DPF. No EOLYS fluid = no regen being completed.

Even if you were to top up the EOLYS correctly you need to tell the car the EOLYS has been topped up. This is by resetting the software counter in the cars computer with the use of VIDA/DICE. So you can also have a situation where DPF and EOLYS has been changed but because software counter has not been reset the car doesn't know it has any fluid left and again will fail on doing regen cycles and thus clogging up the DPF.

Most of this hangs on 2 things, your current mileage and then working out what should have been replaced/topped up when and indeed if they were or not.
