If you replace the DPF and top up the EOLYS fluid tank your emissions system should be good for another 75k. Also check the 2 pressure pipes from the DPF to the pressure sensor mounted beside the battery and make sure that there are no splits in the hoses. They are renowned for wearing through.

Thank you for your sound advice, yes plugged the Vida Dice in again last night and showed Diesel Particulate Filter Blocked. So yo umight be right time for a new DPF. They are quite expensive though, do you not recommend removing it and cleaning it whilst its off, I've seen good results on Youtube, also there are places that clean it for you while its in situ.

Having spoken to a few pretty knowledgeable people in the trade and researched it online I was left of the opinion that any form of cleaning was not going to yield as good a result as a new one. Also, a new one isn't always as expensive as you think. Mine is a genuine Volvo one and was under £300 for the part.

Given we rely on the car as the main family vehicle I concluded it was a false economy to do anything that had a chance of not fixing the issue for a guaranteed 75k more miles.

Yes phoned up a DPF cleaning company locally and they quoted me £75 for a full diagnostic to find out why the DPF as failed/blocked/not doing regen. Which I already suspect why - Eolys Tank Empty - No Additive. I have ordered some now to refill and will use my Vida software to reset it once refilled.
They quoted me £249.00 to do a full DPF clean, I have checked the price of a brand new replacement DPF - aftemarket ones go for around £160 and genuine volvo ones go for around £290 so like you say makes no sense in having the old DPF cleaned you might as well buy a new one.

I was tempted to remove the old DPF and buy some quality DPF cleaning or oven cleaner as this is designed to remove burnt on carbon. And leaving it to soak before jet washing it out and leaving it to dry properly. All a fraction (more or less free) if I get another few years out of it, got to be worth it - No?

Personally I'd still buy a new Volvo one for the peace of mind. Harsh cleaning risks removing the coating on the inside of the DPF that prevents soot from clinging to it that I'm lead to believe is a risk of any cleaning. If that is the case I think any form of cleaning could end up being a false economy.

You pay your money you take your chances I guess.
