DPF Problem

[sirdaniel]

Yes it is the 2.7d. The garage performed a forced regen and all is clear now. Still not sure if this is going to solve the issue long term but will have to see.

Hi , I have owned a 3 Ltr diesel xf for a couple of years now and have been down the problematic DPF road several times .After a forced regen of the system I have avoided poor grades of fuel and found BP and Texaco top grades have made the car far more responsive , they are a bit more expensive but that is all I use now and although I do mainly town miles I have not had a warning light regarding the DPF since , Winns cleaner does help initially but I have been told it's not advisable for prolonged use .

Hope this is useful and enjoy the Jag

Hi Alan,

I also use the premium fuel - Shell V power as there is a Shell Station 500 yards away, and the cheapest fuel in the area - and there is a real difference.  I do try for a longish run once a month.  I also try not to use additives too much.  I think most suggest that no sooner than 3000 miles.

I tend to go by the feel of the engine to check whether it seems to be running well or otherwise.

Sharing experiences is a valuable thing to do, Alan, and appreciated.

Regards

Peter.

Hi Peter , yes the better grade of fuel has made a marked difference to performance ( much more responsive when you put your foot down and mpg ) and eliminating the DPF problems , still give the car a good run regularly which is what it's all about .

All the best Alan

Hi All

I have never tried the 'premium' fuels, but my 2.7 XF covers less than 10 miles a day normally in traffic and I do find that the 'DPF Full' amber warning is seen every couple of months. I think the important thing is to act on the amber warning ASAP as if it goes to a red warning you'll then need the re-gen, so as soon as I see the amber warning I normally follow the handbook instruction of driving for approx 20 minutes at a speed in excess of 30 mph, this always clears the warning.

I do sometimes use an additive to reduce the combustion temperature of the soot particles, the one below that I use recommends usage every third time of filling up.

[sirdaniel]

I completely agree on the fuel. Since I got the car 3 weeks ago I have only used BP ultimate, Shell Fuel Save and Shell V power. I am just praying everything will be fine now. Because its a 2008 car but there were only 42,000 miles on it, it could be the fact that the previous owner didn't give it the runs it needed.  

I got in touch with the local Jaguar dealer this morning and they said it could be the fact that I was driving too fast when the light had come on. He said that 60MPH is the optimum speed for regenerating and if I was driving too fast it wouldn't of kicked in.

Also, the light was on amber, but still required a forced regen.

Hi Dan

Yes I have just checked my Handbook and it definitely says that if 'DPF Full' shows drive for 20 minutes at a minimum of 30 mph, I think a lot of people think they need to "give it a blast" to clear the soot whereas it just needs to reach normal operating temperature for long enough (20 mins) to do the job!

Hopefully yours will settle down now that it's in your hands as 42,000 miles is not a lot for an eight your old Jaguar.

Kevan

Giving the car a bit of a blast can clean out the EGR valves, but as Kevan says a nice steady run at 40 mph is a good test.  If I have not been on a long run in a month, I take the A38 to Burton - on - Trent  --- about 40 miles round trip on a dual carriageway  ---  on a Sunday morning when it is quiet does the car a world of good.

Not posted in here for a while. The last 6 months have been a nightmare with the DPF. I'm now on my third replacement, the first two (long story) it transpired were not regenerating as they were not genuine JLR. The previous were giving red alarm after only two days returned from the garage. It's now been 9 days and no issues so far. The garage has done a lot of free work trying to get it right and it looks like going for the cheap pattern was the wrong decision, they never asked by the way, just said a new one is £1100. I paid £480 last week for the difference. Car feels better than it has done since I bought it June last year. I'm hopeful it's now fixed. Trips up and down the motorway at 65 approx every 250-300 miles will be part of the owning regime going forward. Hint you can tell by the mpg display of your car is doing a regen, don't ignore it, keep it driving at as constant speed as you can on cruise until you see the mpg creeping back up, use one of the other trips to confirm. You should get into the 60's on a steady dual carriageway run. 

Whatever you do don't be tempted by removal  

 

[Old Peter]

I drove down to Brockley in SE London today, some steady driving and some stop start in London Traffic. The DPF should be well clean now, and the total 145 miles was done in under 4 hours  including a stop, and 45.8 mpg was quite satisfactory.

Hi gang

I had this for the first time as I started onoffice car park to leave for home today. Still there when I got home so after the rush hour I had a quick drive down the M1.

Cleared after 10 mins at 70 (I know you only have to do over 30, it says in my hand book). Appears that you must have full working temp first before you try this reset.

Anyway it worked. Town centre driving on visits this morning and afternoon, Jags need to be let loose now and again!

750 miles in and no issues so far. Let's hope it's been put to bed.

That's great Christopher! Fingers crossed!

Wynns produce a DPF cleaner which you can buy at Halfords for £9.99 for a 325ml bottle. Just a fuel additive.

I had a similar problem and used a DPF cleaner additive in the fuel tank. Never had the alarm come in again.

XF 3.0 S 2011:

I had the PDF full warning 2 years ago. The warning was reset several times but came back. Turned out to be a crack in the manifold. The wrong airflow (or something, not an expert) triggered the PDF-sensor, but it had nothing to do with PDF. A very expensive replacement of the manifold solved the problem. 

Just wanted to share the info...

[MarcSwarbrick]

If you’re in the Nottingham area you can’t go wrong with QED Motors, they’ve sorted us out on many occasion with our XF 3.0. This isn’t an ad, they’re just good guys who do a good job for fair price.

Hi mick

Do 50mph on the motorway to regenerate the car don't red line it leave it on auto and that should clear it if not you can get it cleaned for around £250

[Davy B]

Hi Mick

just got my car back yesterday seems ok but I am not £1240 new inlet manifold as it was cracked and I suspect helped fill up the DPF which put on the red triangle and limp mode   2012 xf   Still love the car  but think it may get traded  as if the other side cracks I will have to take in a lodger  Inlet  manifold Replaced and DPF cleaned faults cleared £1240 only done 96k and full jaguar history Jagtech at Teeside fixed it proper motor engineers Jaguar trained 

[Davy B]

Forgot to  ask how do you tell when it has done regen

[Gareth2665]

Hi All

 

I have had a good old head banging with Jaguar over the DPF. If you have the DPF FULL red warning light on the car will not do a passive regeneration. That means it will not regen whilst driving.

I had the Red Warning light recently and after taking it to Jaguar was told ithe DPF needed replacing at a cost of £3993.00. (According to their JLR diagnostic equipment)I subsequently took it to a DPF specialist near me who fixed it for £90.00.

 

In a nutshell.....your ECU guesses the Soot counter and Ash values in the DPF based on driving habits etc.If it gets to a certain level it will perform a passive regeneration whilst you are driving. If the journey you are doing is not long enough to get everything up to temperature to burn off the soot it will not regenerate. If this driving style continues and it does not get to do a regen it then thinks it is full and subsequently gived the dreaded FULL red warning.

I took Mine to Fitch Autos who were brilliant. They did all the tests to confirm it was not full and then did a manual check with a Manometer to confirm there was actually very little soot in there. The soot counters were reset then when it was driven it performed its own regeneratin and works perfectly now.

 

HOWEVER...it has to be checked properly. You cannot just reset the counters as this can cause a fire and serious damage. The values have to be calculated and ckecked by professionals mate.

 

hope this helps....if you need the details of the DPF place i went to let me know

it just shows how Dealer's try to Rip off Owner's, well done in getting it sorted.

Having same issue with dpf red light drove to manchester for a funeral and back thought it would have cleared as usual but not this time. I have 2010 3.0l xf anybody know of somewhere near Liverpool/Wigan that is reasonable for checking and cleaning/clearing error
