Ford Focus DPF

NewArklow2012

I have a 2006 Ford Focus 110bph Diesel with 80,000 miles. Finally the damn DPF has given up. I had known this needed replacing from my last service. The Ford dealer price is just unbelievable, at €1000 just for the part. I’ve been doing a bit of research and rang a garage in Dublin that will remove the DPF and reprogram the computer for about €650. It seems crazy to replace this on an old car.
I do heavy millage, Arklow to Dublin each day.
Anyone had any experience with removing and remapping these?
Many thanks

Can I ask how you know the DPF is gone? There are a number of things that can be done, and equally, can cause problems with that particular engine.

For example, a code scan can yield a P2002 which is DPF efficiency below limits, but this can be caused by a defective pressure sensor or its associated pipework. The cost of rectifying this is a lot less than replacing a DPF.

Incidentally, my wifes car with the same engine has over 100,000 miles, and the DPF is fine - except that sensor packed up and the EOLYS (regeneration fluid) needed topping up!

Hi
Thanks for the reply

I took the car to a Ford dealer last November and the following codes came up p242f and p2458. They told me that the DPF needed replacement then. Im taking the car to a geaarge today so will see what options they come back with.

I'll check those codes later and post back. Can you reconfirm the first code again? Are you sure its not P042F?

Hi

Yes those codes are correct, just reading them from the invoice

A bit of info on P242F

Sorry, forgot the link.

Beaten to it by a better man

There is a test the main dealer can do to eliminate the DPF pressure sensor as being a cause here. Basically, air of a known given pressure is applied to the sensor via its pipes and the live data is read to ensure that the sensor is seeing the pressure correctly. It requires IDS or a similar high-end scan tool to read the correct data though.

If the sensor is ok, a forced regeneration might work.

***EDIT: has that car had any issues with the EGR or intake pipework system? Has it been serviced on schedule using the correct oil?

I wouldn't go as far to say that shamwari....:)...interesting one on the way ford check the differential sensors..:cool:
When you think about it the differential sensors could go out of calibration over a few years of motoring....hmmm you got me thinking now...:D

It's very unlikely that the DPF has to be replaced, they're pretty tough. Something else is causing a fault, as mentioned it could be faulty EGR, wrong oil, lack of fluid and some other things. Get some proper advice and you should get out of this for €200 - 300. If necessary you can go to a Peugeot Citroen dealer (PSA make the engine). Here's a link to a guy on Octane offering a new service, he's a long established member over there: http://www.octane.ie/forum/showthread.php?p=1086569#post1086569

I had to replace a DPF pressure sensor on an 3 year old A4 2.0TDi a few weeks back. It was flagging all sorts of horrible codes that pointed to an imminent DPF meltdown!! New sensor fitted and the car was ok for another two weeks till the DMF then gave a rattle of death....:rolleyes: that's a story for another day.

Thank you all for the detailed responses. I'll let you know how I get on at the garage

Hi, would you mind telling me did you get the EOLYS topup done and if so how much was it?
