Technical And another DPF / EGR problem... worth fighting this one?

[pointyhat]

Doblo '06 1.3 Multijet has been a bit jumpy around 1700rpm for a couple of weeks. Today, engine light comes on, NO limp mode for a change but out comes the OBD2 cable and MultiECUscan.

Two error codes:

1. EGR valve sensor error.
2. DPF clog factor too high.

So first one is usually crapped up EGR valve - happened about two years ago as well. As these are a complete sod to get to in this vehicle, I will refer this one for professional help. However not Fiat this time who charged £200 to clean it, not replace it!

Second one however is more worrying. The DPF clog was 102.2%. So I did a forced regeneration. It has done lots of small journeys around London this month so is sort of expected. However, post forced regen, it's still reading 86.05% which is still pretty high.

I'm not taking this to a Fiat dealer.

So questions:

1. Should I get the EGR refurbished and cleaned or just replace it.
2. What should I do about the DPF. Does anything even need doing to it? Worth regenning it again a couple of times or is that dangerous?
3. Shall I just get rid of it now before it starts costing more?

For the sake of diagnostics:

EGR opens to 67%ish when idling, above about 2800 rpm it goes down to 2%.
