Dpf Problems

paddymc3 · 22-10-2009 04:03PM #1

Just wondering if anyone else is having issues with Dpf's?

I have a Mazda 3 Diesel with a 1.6L PSA engine same as in focus, s40 and most peugeot's an citroen's and the Engine Management Light is repeatedly coming on. Brought to the garage on a number of occasions they refilled the additive tank. then about 2 weeks later it came back.
I have followed most of the advice eg. driving at high revs for 10-15 mins which can sometimes solve the problem short term (a week or two).
Also when the light is on the engine sounds very rough expecially at idle!

Any ideas??

What milage have you coverd....??
The 1.6 hdi (110bhp) engines are much the same as yours and have
dpf issiues around 80 - 100k.
Normally when this fault comes up Peugeot normally just change the partical filter and top up the additive tank with eloys 176 ...reset the system.

I've got a 407 1.6hdi myself and it had " partical filter regeneration urgent "
@ around 77k.
I just topped up the additive tank myself and reset the system with planet 2000 (peugeots diagnostic equip) all is fine since..:)
it cost me 110 euros for the additive.
Peugeot normally charge 8-850 euros to replace the dpf and top up the additive tank...:eek:

You need to check the filter condition with some good diagnostic equip and look into live data see whats the pressure across the filter is e.g. Clean..getting blocked...or blocked.

Is the dpf regenerating every 3-400 miles ...??

Ouch 800 euros!!
its covered 90k miles and ran for a while without any fluid in the system.
Dpf if regenerating a good bit more often than every 3-4k probably more in the region of every 5-600 miles.
Problem with the mazda is it has no specific dpf warning system just the engine management light.

Is a main dealer only place i am going to find the proper diagnostic equipment??

I've also heard of people removing and cleaning the dpf's do you happen to know if this is viable and/or how successful it is??

If the dpf is regenerating every 5-600 miles that seems normal.

Most diagnostic equipment like launch x431..Dec superscan..snapon ..etc
should be able to check the condition of the filter....I use planet 2000
which is what Peugoet garages use...:D
As for cleaning the dpf it is possible and its a cheaper option..:)
when peugeot remove the old dpf it is sent off for cleaning and someone
else gets it as a replacment/reconditioned part...:rolleyes:

Usally remove the dpf...power hose it opposite to exhaust flow... blow out (dry)with airline and refit...maybe run the engine with the exhaust disconnected until the dpf dries out fully.....:)
I must remove my own and give it a power wash when i get time......:rolleyes:

On the 1.6 hdi the dpf is to the front of the engine and is easily acessed
for removal.
Also on these engines you have to tell the dpf ecu that your after fitting a new dpf....I did this on mine and it cleared all the faults.

below is a diagram of the 1.6 hdi (dv6) dpf which i guess is the same on yours...

if you want information on the removal of the dpf from the 1.6 hdi
P.M. me your email address and i can send you on some info.

Can the dpf be removed and repaced without any diagnostic needed

Yes it can be replaced without diagnostic equipment but it may need the equipment to clear the dpf message.
What problems are you having....??
If you topup your additive tank it will need to be reset with planet
(peugeot diagnostic equipment)

The DPF should have two small pipes coming from the body of it which connect to a differential pressure sensor. The hoses which connect the DPF to that sensor can get damaged and generate a false error code relating to DPF efficiency, or the sensor itself can sometimes go faulty. If your car is in the zone mileage wise then it probably is the DPF. Someone with an appropriate scanner which can read the live data should be able to see what pressures the sensor is reporting, and determine if the error is genuine (which it probably is). Some DPF's are available from spurious suppliers. I know some are for the DV6 which is fitted to the Ford Focus.

beetlefan · 23-05-2010 07:10PM

my 307 hdi is the 110 bhp model and it has done 57k miles. The problem is that the fan comes on almost every time after doing any journey and stays on for up to 10 mins, which is a pain as it is very loud . I had to replace the battery not too long ago and if the fan does not stop soon i will have to replace it again soon.

Row · 23-05-2010 10:03PM

If the fan is running all the time then theres something calling for it to run all the time or maybe one of the fan relays has gone faulty.
Dpf regens can also bring on the cooling fan if its regening to often....but with 57k your dpf should be o.k.
Think you may need to get a diagnostic check to find out where the problem
lies....

beetlefan · 24-05-2010 11:18AM

thanks can you do a diagnostic check on my car? and if so where are you located, i am in mayo but am in galway most weeks

Row · 24-05-2010 01:59PM

Hi beetlefan,
ye i can have a look for you....If you pm me your vin number i can have a
look at what you have.I'm around 10 min drive from Claregalway out the
Roscommon road (N63).
Ron.

I think you will find Sportchip is highly recomended in dublin
he can switch off DPF so you can remove it or leave it with no errors and forget about the problem

Have you any idea of the cost...??

scooby girl no1 · 04-06-2010 11:50AM

I might be totally wrong but he was doing it for €350;
I think it's cheaper now but you'll better look on web or give him a call

Row · 04-06-2010 01:28PM

Thanks scooby girl no1,
Think i'll stick with power washing my own dpf,it should be then good for another 100k or so..:)

Row, are you saying you can use Planet to connect to mazda for regen/reset additive qty??
Have planet & lexia myself but always use Carman for the japs
just wondering as I dont have IDS for Ford/Mazda.

I was referring to a 307 hdi on that reply.....I don't think planet/lexia will work
with ford/mazda as they use different ecu's..it maybe worth a try tho...:)

crosshair1 · 04-06-2010 10:06PM

Ok didnt realise, was pretty sure it couldnt be done but
as its a lot cheaper than IDs would be great if it did.

On my focus, 2 hoses which appear to be coming from the DPF back to the sensor have blown off, I have had a ENGINE SYSTEMS FAULT on my dash for the past while and have sent the car back to the garage to get topped up with the additive but the problem never seemed to be solved. My car is now with a ford dealer getting the pipes replaced and hopefully that clears the problem. However if the problem is with the filter can i get the it cleared as the last thing i want to do is pay out for a new DPF.

I have a 05 1.6 tdci ford focus, the 2 pipes which comes from the dpf to the sensors have blown off and are currently been replaced at a ford dealer, however if my dpf needs replacing i am running into big cost and is something i would rather not do. There is 96k on the car at the moment. I would like to try cleaning the DPF before i replace it and would appreciate if you could send me your information or any thoughts you would have on my problem.

Afaik the Focus uses a different dpf which can't be split like the peugeot/citroen dpf.
maybe they can still be cleaned but not sure how successful cleaning is on the focus dpf...

maybe ring around a few ford garages (up north maybe) and get a quote on a new dpf+additive toppup and see how it compairs to down here.
Best of luck with it...;)

I think its the one unit on the ford, the cat and the DPF together. The mechanic in work told me it injects fuel into it to clear it out, is this the additive your on about or does it use diesel fuel?

I think the additive is added to the fuel and that must be what clears it out.

The additive is injected into the fuel tank where the signal is taken from the fuel cap sensor which knows when you top up or add diesel.it also takes into account how much diesel is actually in the tank so the correct amount of additive is injected....The additive reduces the burning off temp of the sooth in the dpf from around 550deg c to around 450degs c so it regens faster and less heat is required to carry out a regen.

I have bought the additive before but not sure if it was put in correctly, is it a big job to refill the additive or how is that done?

when you buy the additive it comes in a kit which makes it pretty straight forward to topup...but you will need some good diagnostic equipment to reset the system...otherwise it will not know it was topped up.
just be carful as this additive can be nasty stuff.

Yes i got the kit with the additive however the garage i sent it to only had a handheld diagnostic kit so maybe they were unable to reset the system properly. i wil get the ford garage to top up/reset the system.

While looking for something else, i found a place selling the DPF fluid:http://www.stationautoservices.co.uk/jlm/store/products-delivery-service/
I'm not connected with them but just thought i'd share the find.

edit: I dont think they deliver to Ireland. aaarrggghhhh! why not???

TrevTbar · 31-03-2011 04:42PM

Anyone know the best place to find a Catylic Convertor/Dpf for a 05 1.6L ford Focus. The pipes going for the dpf to the sensor blew off because of the pressure. The Convertor/dpf seems to be completely blocked and needs changing. Got a quote from ford garage for 1140euro!!! Any ideas of cheaper options???

shedweller · 31-03-2011 05:00PM

I believe the usual way is to remove (lol, there's a simplification!) the filter then use a pressure washer through it to clean it out. A shot of compressed air to remove water is done afterwards although leaving it on a radiator overnight should do the trick.
Here's a BMW owner doing the job:http://forums.5series.net/topic/94725-diy-maintenance-for-the-dpf/
He's using a leaf blower to dry it out after cleaning. Class!

Good luck and let us know how you get on.
