Search results for query: dpf

Not uncommon to get the ‘hot’ smell when the van is doing a dpf regen, have a search if your not sure what this is but basically the engine raises exhaust temperatures to burn off ash in the dpf filter, normally happens twice per tank of fuel (ish)

an exchange vw dpf was about £2.5k fitted by Retro Resus last year in my 108 BiTDI

the new DPF needs coding in, or "setting the defaults" - so the ECM expects a new DPF vs a learned blocked one.

This being done under warranty? Running low fuel will prevent regens. Which can leads to excessive dpf buildup. The dpf can be flushed with a mobile guy and chemical etc. So you paying for this, or is this warranty.?

Dpf left in situ, though if I’m honest that will get deleted if it gives up the ghost. Primarily left in place due to obvious MOT concerns New EGR June 23, coded out but not plated out.

Sorry to hear. Been there. £2,200 it cost me for a new DPF and NOX sensor. Refurb.

...no faults or warnings at all. Have attached the detailed engine report. No soot in the tailpipe. Is this because its all stuck back up at the dpf? Has anyone used these DPF cleaning firms that go through the sensor port yo clean instead of taking it out? Is it any good? Would have thought it...

And when combined with the egr it’s a recipe for engine destruction.

How often does it regen? I ran too long with a clogged dpf resulting in turbo failure...

I need to get that app :) I’m interested in unravelling the mysteries of the DPF :) Oil ash is low, it’s limit is set in the ECU somewhere, I think around 100g ash. I can’t comment on the other numbers as I haven’t studied DPF enough yet sorry. But some others will be along to help soon I am...

...and expensive to replace. Blanking and / or coding it out will benefit the engine heaps, and improve mpg and longevity… is there an upgraded DPF out there? Or a more efficient exhaust system? Will it make a difference? (I accept the legal aspects and emissions etc) I use high quality and...

You’ve been dealt a rough hand there! If it’s any consolation I’m pretty dam sure my turbo and dpf are a ticking time bomb, just patiently waiting to soil itself at the most inconvenient time possible

Cheers. Is this a big job?

Long overdue update. They sent lots of data to VW and eventually….you guessed it….. replace DPF :slow rofl: He kept saying that on their inspection it looked fine but you can’t see anything inside the DPF with a visual inspection anyway so I always thought that was nonsense. I’m laughing not...

...well documented here and all over the internet but I'd like to hear from people whos vans have had a replacement engine and either: a) had a new DPF/EGR fitted b) kept the same DPF/EGR with a new engine (this is what the previous owner did with mine, hence another new engine needed!) c)...

Except removing any/all of those things is illegal. Egr and ad blue are just software solutions. Dpf involves physical work in altering the dpf internals. If it gets discovered and fails it’s mot you’ll have to shell out a couple of grand for a new one. I’d leave the dpf alone.

Anyone tried a DIY? Some video on YouTube. Desolves the carbon soaking in DPF cleaner

Yep- seems to be the consensus that with removal, proper clean and refit the dpf has had it's day anyway so that's fairly pointless.... Don't want to destroy this lovely new turbo! Also don't want to spend more money but it's looking inevitable. @WinFreak I know you had a lot of other issues-...

Just got this back following turbo and DPF replacement. Assuming this is within normal parameters, but just wanted to get other opinions.
