Hi all, not sure if this is in right place but I’m looking for some advice
I have a c220d and have had it about two years. After about a month dpf was blocked and garage did a forced regen and I was advised to drive on motorways etc etc.
however the issue keeps coming back. I have had it Terracleaned also. I also have a fault saying swirl flap 1 jammed closed.
How can I fix this once and for all without dpf and swirl flap delete?
the finance company wouldn’t help despite the garage having to do forced regen in first month. I thought it was fixed but then few months later (out of warranty it comes back).

Many thanks in advance

I'd imagine you'd have to renew the manifolds and offending swirl flap . Some swirl flap mechanisms are made of plastic and can break. I've seen a company that produces aluminium ones , that's maybe something to consider .

Unfortunately emissions related équipement, is badly thought out, unreliable and a money pit to sort out. Have a go at fixing it, if it turns into a ball ache, delete what does not compromise any MOT inspection. Currently the emissions related equipment is a maker license to print money at owners expense, and they sure take advantage of it. Good luck.

Thanks for reply. I was told today to replace exhaust sensor by the guy who done the carbon clean.
It’s a headache tbh I’ve had the car 2 years and half that time been spent with dpf issues.
I’ve had a quote for £450 to delete dpf and swirl flaps. I don’t want to do this but feel I have no option.

£450 is expensive.

From reading many posts these "deletes" cause more problems down the line if the map is no good. Good luck with is all.

I understand that possibility. But frankly if it can pass mot, for now, I think its a solution. To keep throwing £1000,s at a non permanent solution is not. Especially when the real cost is a few 100. Emissions related parts need price controls, currently we are all getting mugged for it, if prices were not such a rip off most, me incl would not be deleting any of it. Given my total adblue system was replaced just before I bought it and 18k later its screwed again I certainly see no point in paying to replace iit again. Lesson really don't buy post euro 5 diesel. Or come to that egr dpf equipped motors of any fuel type.
What's green about throwing ur car away at 8.1 Yr because makers install crxp software and hardware basically designed to cost owner a fortune,and be uneconomic to repair. I think today consumers are treated as cash cows, not valued customers.

Deleting the ad blue can cause the dpf to not do a regen . If the ad blue solution applied is an old file , the mappers seem to of overcome this issue now and rewritten files , totally deleting the egr , dpf and ad blue would be the best solution.

Are you certain it's a blocked dpf and not a dpf pressure sensor giving false information.

According to the diagnostics it’s dpf blocked (soot level) but can’t be sure personally would the diagnostics of picked that up

They are very much related when it comes to error codes . A knackered pressure sensor can give a 400% soot level , even though the dpf is clean.

Deliberately misleading info I suspect, for anyone not familiar with the possibility. No accident methinks.

More of not publishing the truth than actually telling fibs, or simply misinformation alla diesel gate, mb version.

Sounds like the swirl flap motor has failed to me. It will flag a DPF code because the engine sees a fault and knows it will block.

Its there actually to prevent constant regeneration caused by limp mode. The disparity in software between soot and ash content will stop a regeneration cycle as the target thresholds will be out of spec.

It's a consequential fault code to be reprogrammed once the cause of the limp mode has been fixed.

But a good garage would know this already....;););)

You would think so . Think there's more than a dpf being rinsed tbh.

A continuously blocking DPF can a symptom of a fault elsewhere - for example boost leaks from intercooler hoses or a holes intercooler. Theses cause the engine to think there is more air available for combustion than there really is so it insects too much fuel creating soot which the DPF captures causing frequent regens.
