Default Sportage 2006 CRD DPF cleaning

Hi,

I keep getting the DPF warning light up, and have been told that either the Deisel Particulate Filter has died or it's not going into a cleaning cycle anymore.

I'm praying the filters OK as a new one is over a grand (£1000), but kia did some work a while ago and forced the system into a cleaning cycle, why, none knows, but it seemed to help????

Does anyone know how to get the car to start a cleaning cycle manually, or will some of the shop bought cleaning additives work, or will they screw up the engine/cat/exhaust?????

By the way the light flashes, then later on stays on, but after a day goes out??????

Any help will be appreciated!!!!

Default DPF Cleaning

Hi Starlitz,

The Garage will force a DPF clean by connecting to the CPU & setting it to clean by injecting extra fuel just after the compression stroke,this unburnt fuel then reacts with the cat in the first part of the DPF to raise the exhaust temp to burn off the soot deposits which are blocking the filter,turning them in ash particules that are even smaller & will blow out the back,that is how i understand it!,I use millers fuel injector additive to the tank(last 18 months)gives a nice smooth engine & had no problems so far.

As for a manual way to start the process i do not think there is,but if you find out please tell!

The light flashing is telling you the filter is blocking up,a good run with rpm at 2000 or above for awhile usually starts a clean & sorts its self out if the filter is not to badly blocked.(i think the clean process takes about 20-30 mins)

cheers,

Gazcaz

Thanks Gazcaz,

It was the forcing of the cleaning cycle I'm interested in, especially as the dealer couldn't explain the overly hot exhaust, caused by the cleaning cycle for nearly 2 years, (lost faith at that point).

I have bought a canbus reader/thingy, and was hoping that i could check to see if the dpf cleaning cycle is operating Ok.

As for the millers fuel injector additive, where can I get it??

Cheers

Hi starlitz,

Strange a dealer does not know how a DPF works, but there you go!

Anyway i get the millers diesel power ecomax from halfords,about £12 a bottle & lasts me just under a year.

You can get it off the net slightly cheeper if you wish.

As for the regeneration cycle of the DPF it woud have been better if there was a dash indicator to tell you? but perhaps they thought it would confuse some?

Cheers.

In my experience the 3 dealers I have dealt with don't appear to keep up with newer models and technology., if the book don't say it they can't do it!!


And they charge way over the top to do anything, no wonder they can afford to give us free coffee in the dealership!!!!

Hi Starlitz,

I noticed the other day i was wrong on the time for a regenertion,after reading an AA article on the net they say it is only takes 5-10 mins, whether it is a passive or active regen.

So if the engine & exhaust are hot & you are doing 2000 rpm or more for more than 10 mins it should keep the soot level clear.

Gazcaz.
