D5 (2005 on) V70 -07 DPF issues but can't get anyone to help sort it.

[Charliek]

Hello,

I am new to the forums but hope the community can help. I'll try to keep it short but in order to give the whole story, it's likely not to be! I initially posted to the General forum but think this may be better. Apologies if you've read it there as well.

I've got a V70 D5 2007 185bhp 132K (My third V70 but 1st 185bhp DPF one - I wish I'd stuck to the old 163bhp versions!)

I bought it in April at a good price but think it had problems when I bought it. I bought it privately so accept 'sold as seen' though, so I have tried to deal with issues.

In May, after some stuttering occasionally when accelerating I had the initial things sorted, replaced glowplugs and had a 'manifold runner repair kit' fitted by my mechanic who is a good guy although not a V70 specialist.

A previous problem of the car going to limp mode and 'engine system service' required appearing still occurred when accelerating moderately hard i.e above about 3000/3500 rpm. Advised new turbo needed. My mechanic has diagnostic software although think generic and not Vida. Turbo fitted. So now £1000 post-purchase costs incurred. The problem still occurred, so ended up driving more conservatively!

More recently I've been getting the same 'engine system service' appearing and the 'soot filter full' message. I have no idea if connected to previous issues.

Initially my mechanic just reset the codes and we didn't look to resolve the issue but after it did it again I got a DPF guy to come out who advised, after using software, that regeneration not occurring so I needed to resolve the issues that were causing that first and that I should change the DPF pressure sensor, DPF temperature sensor, glow plug control module and thermostat as these may be causing the regen to not happen.

A second opinion by a Volvo specialist local(ish) to me basically condemned the car. They weren't really specific, I didn't really want to hear it and I got the impression that they just didn't want to try and sort the problem.

So where do I go from here? Get rid of it for peanuts? Not something I want to do.

Can anyone advise what they would do and/or who I could take it to in the Peterborough, Sleaford, Grantham area who have good knowledge of Volvos and DPF issues? I really don't want to go to a Volvo dealer to either get codes read or to fix it. I can't afford that!

I am happy to spend money on it but not if it doesn't get me a car that will go 'for a bit'. Happy to sell for a reasonable figure but as it is that won't be a good amount and I don't want to sell it without disclosing the issues for the new owner.

Any help is gratefully received and thanks for reading this. Please let me know if I should actually post in the V70 forum.

Charlie.

I think for all the money you could throw at it, spend ~£100 on a Vida kit from Cheshired5 and understand what's really causing the messages, then it can be dealt with properly, whether you do the work yourself or advise your mechanic.

For instance, on my D3, it can generate a fault saying EGR low flow (in Vida) however knowing that's not the case as I had already cleaned it, the fault was cured by replacing the TMAP sensor on the intercooler. Once you can get a visual of the faults recorded it will be easier to diagnose.

If your getting those messages and soot filter full I’d be guessing a boost leak somewhere or on the intake I had the same and it was the pipe under the engine.

I’m guessing the previous owner couldn’t find it either so sold it on, even a tiny hole will cause issues, it could be the intercooler as well.

If you can’t pin point it I think you can get those smoke tests to help.

But I would check every pipe and connection even if you get someone to rev it while you look.

check all the rubber hoses that go to the dpf pressure sensor and look for broken wires at the sensor plug. egr valves can also fail or to stick open. a good diagnostic tool is your best place to start. ask if any members are near who can help you

[Charliek]

Thanks everyone for your help.

Yes looks like I need the codes read properly.

Anyone local who can help me with that?

If not it may be time to purchase something suitable myself.

[Simmy]

also try asking on face book groups like torquevolvo or vt there are dozens of cross linked groups join some and put out a request for someone who has vida dice equipment . its only just in to new year so it might take a day or so.

The scatterbomb approach to diagnosis rarely works. It needs to be examined by someone that know that theyre doing. The specialist clearly doesn't, so that leaves a dealer.

Take it to a dealer. An hours labour to diagnose it will enable you to make an informed decision. More often than not the faults that trigger DPF symptoms are usually (not invariably , butn its rare to be otherwise) fairly minor and inexpensive once they have neen pinned down.

The good news is that these dry systems don't cause problems on their own. Its invariably a fault elsewhere that makes them misbehave, and even without the DPF youd still have the fault to identify and address. The is no additive system, the filter themselves are huge by DPF standards and near on impossible to block unless a faulty engine chokes them up, there is little per se to be wary of.
