... but I can't find the same scenario as mine.
Hi folks, hoping for some solid knowledge here, I'm sure there's been plenty of experience of similar issues. My personal tale of woe here.
OK, my old 2007 2.2d suddenly developed the yellow DPF full warning. Searched the forums and found a whole heap of possibilities which just confused the hell outta me. Found one post where a chap put some DPF cleaner in the tank and problem went away..... not for me I'm afraid, I went from yellow to red warning a couple of days later after trying twice to force a regen with a couple of long drives with higher revs... no joy there. I then looked for a 'specialist' cleaner, an hours drive from me, who removes the DPF, rather than flushing through the ports, and has a specific machine just for blasting out the DPF. By this time the engine is running really rough and it was an effort to actually get it there. He cleaned it, replaced the 2 sensor pipes, as they had melted, and the car ran better, but not great on the way home, next day yellow warning was back. He was now on holiday for a week, but I returned the car under warranty. He then highlighted that the DPF pressure sensor was dead (No mention previously). I bought a replacement, he fitted it, cleaned the DPF a second time and that's where I am now. I don't have any warning lights at the moment, yellow or red, but the car is still running really lumpy. I'm not bothering to return the car again as it was clear to me he had nothing other than cleaning to offer.
I have it booked in for an oil/filter change next week, as it would almost certainly have dumped diesel into the sump, and I'm barely using it, only for occasional very short trips where I have to. I'm suffering better half's Honda for work but sometimes she steals her own car back from me!!!
The car has about 170,000 on the clock and I have no idea if the DPF is original. I've seen a number of posts where people have had similar symptoms but the root cause has turned out to be from something else entirely, so I'm at a bit of a loss as what to look at next to eradicate the issue. I'm thinking of stripping the EGR off and giving that a clean, just in case it contributes in any way.
Any thoughts folks?

Have you had the codes read - not only might that highlight any additional issues, but also if your exhaust temp sensor or the glow plugs are not working that will prevent passive re-generation from occurring which might have caused the initial problem.
Though I have to say if the sensor pipes were bad and/or the sensor was bad then it might not have needed cleaning.
Otherwise "running lumpy" could be anything, an EGR and intake clean certainly would not hurt but may not be the issue..

Hi x-files
Thanks for the reply.
It seems I spoke too soon and red 'DPF full' warning is back this morning. I did have the codes read, and the only code showing after the 2nd clean was my radiator fans, which run constantly and have done ever since I had the car 5 years ago, there were no other errors showing at all. On the 2nd clean, they also commented that the cat was also clogged, as it was backing up from the DPF due to that not regenerating. I'm unsure where to go with this, do I replace the DPF? Does the cat need replacing also? Is there some other underlying issue that is affecting this which is stopping it regenerating. It's a bit of a minefield and I don't know how to try and determine what needs replacing, as the DPF and the cat will not be cheap options for a trial and error attempt.

Was the DPF counter re-set in the computer after cleaning?
Also one way the ECU determines if the DPF is full is the differential pressure sensor -did you buy a Jag or OEM one and are you certain the pipes went back on the right way round. It's something that can be seen in live scan data.

If you drive the car regularly with the opportunity for re-gen - ie 20mins over 50pmh then you should not have any DPF issues - if you do there is an underlying reason. I would find the issue with the fans, if they are on because of a temperature sensor then again that may stop DPF re-gen.
Really you need someone with some diagnostic skills to find out what the actual issue is - DPF issues are symptoms not the cause (though sometimes the cause is the wrong sort of use for a car with a DPF)

Thanks again x-files
Ha, I knew it would be tricky bugger. I've just found an indie Jag specialist not too far from me in Derby (MGA Jaguar) I think I'll give them a call and see what they say.
I hadn't even heard of the DPF counter, so I doubt that it was reset.
My daily drive is about 25mins, with about 50% of it around 50mph

Why is nothing ever simple?
I think if I can get it sorted, I'll offload and get a petrol motor again!!!! Feckin' DPF's

From my experience most DPF problems start with bad combustion resulting in more soot in the exhaust causing the DPF fault, common faults are the EGR v/v not seated or operating properly or a leak in the turbo piping either a split hose or a corroded jubilee clip.
Both worth looking at first!

Thanks cam, I plan to strip the EGR at the weekend
Just be carful if it’s the 5 port egr you cannot disassemble and a new or used one is impossible to find
I found out to my mistake car now gone .

Thanks Roger. I should probably clarify, I plan to remove and clean the EGR, if required. I'm not skilled enough, I think, for a full strip down and re-assemble. I will go carefully.

If you like your x type, and you can cope with a manual, get a 2.0d! no DPF there, ever.

Hi Euan. I really like my X-Type and I normally drive a manual, I only bought this auto as I liked the red, chequered leather/carbon fibre interior and it just happened to be an auto. I had never heard of a DPF prior to this issue, my previous car was a 2005 2.2d Sov, which I think was pre-DPF. If I can get this issue sorted, I will definitely be looking at a different option

Just remember the EGR ,DPF,and TURBO actuator are all linked.

Will do Roger. My mechanical skills are old school, and not up to the new fangled electronic gizmos, so I know enough to leave well alone things I don't understand. I'll take a peak at the EGR and see if there's anything obvious. I've booked the car in at the indie Jag place, but everyone is so busy, they can't fit me in until 18/10. Oh well, it is what it is, I'll report back when I have anything worth reporting back on.

There is a Thread on this Forum in the X Type Section, that a member states that it's better to replace with New as that type off EGR is not worth or there's No benefit in trying to Clean it and as Roger says they're very difficult to find.

Further to what @roger777 states if it is the EGR with map sensor they do not respond well to cleaning.
While you are waiting for a garage I would have someone rev the engine while you listen for a "whooshing" noise also run your hand down the pipe below the EGR and feel for air escaping.
If the turbo pipes are intact I would fit a full blank to your EGR and run like that for a while to see if there is an improvement, you will get an EML and a P0401 code but it will reset when the blanks come out.

It's been said that if you're going to fit a Blanking Plate Permanently it needs a 8 or 10 mm Hole in it.
Cam has given you something to go on there and you now know what you'll be doing at the Weekend.

This may be a radical option, and a step too far for some.....but, seriously consider a DPF/EGR delete. I got it done a while back and no more issues, more importantly no fuel dilution. And for the naysayers, I just passed the MOT again last week, emission readings all well within the specs.

This is illegal in the uk and and will not pass a MOT

The reason I said to use a full face blanking plate was to prove if the EGR v/v is not seated properly and passing exhaust gas constantly, it will give an EML and P0401 but so does a blanking plate with a hole in warm weather in some cars, but with a hole it will still pas gasses at the wrong time causing poor combustion, just a quick cheap short term check!
