V50 2.0D - Ongoing DPF issue *Help please!*

[CoreyDog]

Hi all,

So I own a V50 2.0D on an 08. Great car with one major current issue, the DPF.

I had the "Soot Filter Full" appear so took car to local Volvo Specialist, apparently fault code on VIDA came back as conditions unsuitable for regen, odd since came on when doing 75mph on M1 for over 2 hours. Anyways, replaced DPF with an aftermarket and went away. On drive home car put itself in limp mode with engine service required. Turned out needed a new DPF sensor, sensor fitted and away I go.

Few days later, DPF Soot Filter Full up again. Back to garage and again showing Unsuitable Conditions. Garage recommend just to keep running it and keep an eye on it.

Two weeks later (Numerous Soot Filter Full messages later), driving up M11, DPF light on and stayed on. 20 mins later car in limp mode. Back to Volvo Specialist, new DPF is completely blocked, VIDA showing Unsuitable Conditions code, DPF pressure codes etc. So fitted a genuine Volvo DPF (Wow, they are expensive), away I go again. All pipes checked and perfectly fine.

Well, today after only 189 miles with new Volvo DPF, on the M1 at just under 80, DPF "Soot Filter Full" is back!

I'm ready to scream, I have spent close to £1000 on this and don't seem to be anywhere with it. Garage did say if warning came back, they would be stuck as what to do next.

Anyone have any ideas at all? I'm considering getting rid of DPF altogether, cost another £450, but I'm thinking that's the problem gone and never to return.

Please help....

Volvo told me that there was a tank that also needed topping up on my S40 2.0D, if the tank is empty then the car cannot re-gen and will throw an error.

also worth giving it a good thrashing and a nice long journey, preferably with a tank of decent fuel (BP/Shell etc), it could be that the exhaust manifold/turbo/EGR are full of st and clogging the DPF.

Another option is that your turbo is fooked and is chucking oil into the DPF causing it to clog?

Yes, as I understand it these use the Eolys additive system like the Peugeots and Citroens that share the same power train. There's a tank that needs topping up every 36k or so (Less if you don't brim the fuel tank every time, as the dose is triggered by the fuel cap opening and is the same regardless of how much fuel is put in)
That said, low additive should trigger a warning and fault codes of its own

Is the engine running correctly? is it producing too much soot? Injectors etc all good and not worn? I know the Mondeo Diesels are a pig for leaking injectors. No offense but its a ste engine, sounds like a tractor and has its fair share of problems - get rid and get a D5

Don't agree at all. It is quite a smooth engine - in some ways smoother than post-2006 2.4D/D5 engines which are pretty rough. Injectors don't tend to give trouble on them.
