2.2 dpfissyes.

[Jamesh]

My new van a ford transit 2.2 mk8 has a dpf issue. The dash is saying exhaust filter full.

I cannot get it to regen despite driving 250 miles yesterday. Much if it in limp mode....

Any ideas? Garage suggesting clean / delete / new dpf....
Booked in Wednesday.

Cheers James

There are known issues with the sensors on the transit dpf. A forced regen from the ecu can be done using Forscan via the OBD port

 

[Phill D]

As said above, check dpf sensors first. If they are good and the dpf is blocked then a forced regen via the ecu.
I am told that forced regents can only be done twice before the dpf is shot. But I cannot confirm that.
Occasionally a dpf can be so badly blocked that it needs replacing.
Not cheap....

we had a Dpf type warning light come on (on a Peugeot boxer) and it turned out it was to indicate low adblue, could that be the case with yours?

 

[Jamesh]

It did say low ad blue so I topped it up.

Then it continued to say low ad blue despite adding 5l of ad blue.

It wouldn't regen despite running at 3000rpm for best part of an hour.

Im hoping the garage can force a regen on it!

Otherwise it will be a new dpf. I've found one which hopefully fits for £360 from EEC which isn't bad??

Our dpf light didn’t go off until we next restarted the ignition. Fingers crossed you can get it sorted!

 

[Phill D]

Now that you have topped up the ad blue, try disconnecting the cab battery earth for several minutes then replace it.
The ecu may then search for its parameters and all be OK.
Worth a try

The atomiser for the dpf regen injection device is probably blocked. It is in the exhaust before the dpf buy needs a code reader to prime the small injector pump if cleaned or replaced - a garage job I suspect.

 

[Jamesh]

Update....

Garage have said they couldn't force a regeneration so I can

1) Have it removed and decoked.

2) have it removed and deleted -illegal!

3) have a new one fitted at £700+ fitting.

Cheers James

I would go with Phils idea. It almost like a reset,,you’ve got nothing to lose,,

[Phill D]

How will they decoke it, the inside is like a carbon fine honeycomb, I can only guess by chemicals which I suggest is likely to reduce the life of the dpf as it will eat some of it away.

The thing u would want to know is what caused the blocking to become so extreme so that the normal process could not burn it off, what else is not doing what it should..

 

[Wabs]

other than that have you thought about a carbon deep clean? There are a few companies that do it and they are mobile.

 

[Wabs]

By chance, I’m having my Range done tomorrow, I’ll let you know how it goes if you like,my neighbour has has his camper and two cars done and said the difference is amazing,,,let me know

 

[Phill D]

Just to make the point..... If you know what caused this then that's fine and can be avoided or sorted.
But,
If you don't then there is a strong chance of it happening again and your hard earned money will be down the drain.

tell them no;2 but to remove the internals & refit. or no;1 & remove interals & refit

Or No.4 - go to a garage than can check the atomizer

 

[Phill D]

And re map at thed same time

 

[Jamesh]

Thanks guys.

Let me know how the range rover gets on.

Will get them to check the atomiser.....

I think it's done alot of low speed driving and it's limited to 60mph.... Needs a derestriction + remap!

Cheers James

Definately a re map,,,

 

[Wabs]

Little update as promised,,,had the car carbon cleaned today and a little re map done.All very tidy work,,just taken her out for a drive and the difference is VERY noticeable,,so I would recommend it,,,good luck James with your issues,hope it gets resolved,

Correct answer the atomiser has blown new one from ford hope it works.

That's a good result. I might get it done at some point. How much did it cost?

Cheers James

 

[Wabs]

£ 380,,,it may sound pricey, but it cleans all the sooty build up from the engine, that price included the re map, I’m going to get the MH done soon,,glad to see you have sorted your issue out

 

[Jamesh]

Van back from garage running fine!

Do you think a in the tank dpf cleaner would help?

Thanks for all the help.

The atomizer really needs to be removed and cleaned or replaced. It sits in the exhaust upstream of the dpf and gets blocked with crud from the engine. It's purpose is to inject diesel and ignite it to get the dpf to regenerate. If it isn't working the dpf will never regenerate and clog up pretty quickly.

Cant do any harm,

The injected diesel doesn't ignite, the increase in exhaust gas temperature is generated by a catalytic reaction within the oxidation catalyst.

Not sure about the transit but the Citroen version ignites it with a glorified glow plug and fuel injector

 

[gus-lopez]

If it is restricted to 60 mph that wants removing asap.Otherwise til then drive using 3rd as top gear.

 

[Jamesh]

I agreed getting it done asap!

Is it worth remapping?

Also the is apparently a software update to inform you its regening so might ask about that too.

Cheers James

A now atomiser was fitted.
