DPF full

Hi Rik.

I think when you have a red light, you have to get a forced regeneration at a garage.

Doesn't your handbook explain what to do, what i'm led to believe is if you have a yellow light you can go for a 20/30 minute drive after the engine is up to normal temperature (ie a Hot engine ) to get a complete regeneration. When a Regeneration is starting with my car I find that the the engine revs are idling higher than normal ( up by about 150 revs ) or the exhaust is making a louder noise than usual ( as if there's a hole in the exhaust )  if this is happening don't switch off the engine and go for a drive. Diesels are meant to be Driven as some members say give it a Italian tune or sometimes drive it as if you had stolen it.

In nearly 6 years i've never had a warning light come on, i've certainly had a few Regenerations and they can occur when your not suspecting it ( I was recently driving to the Cairnryan ferry and after travelling some 120 miles I pulled into a service station and yep a Regeneration was taking place so just carried on driving and the engine idling revs were back to normal after about another 10 miles ).

If a Regeneration is interrupted ( ie the engine being switched off diesel can enter the sump pushing up the Oil level witch can cause problems ) which is why most member's put less Oil into the engine than is mentioned in the Handbook.

I only use 5:5 litres instead off 6 litres and use a Low Ash C1 Oil WSS M2C 934B this is the oil Jaguar are now using and we advise to use only genuine Jaguar oil and fuel filters. There's also a debate about what diesel too use some members say to use Shell V Power Diesel Or another premium diesel.

I hope this has helped in some way, when buying a car it is usually recommended by members to get all fluids and filters changed and then you know how things are within the engine .

Regards Tom.

Hi Rik,

Tom has given you a perfect answer.

While I have never had the amber light come on in respect of the DPF I have had it come on with the EGR sticking, and to clean out the fuel system I give the fuel tank a shot of Millers Oils Diesel Power ECO MAX every other fill up  -- about ever 6 weeks  - which seems to help, as I don't do long runs that frequently.

Regards,

Peter.

Hi Rick, my xf 3.0ltr 2009 went into the dreaded red two weeks ago and I assume yours has gone into limp mode.I cleared mine by a hour and a half drive on the motorway, when I got home the car was still showing DPF full and still in limp mode but shut the car down completely ( double lock on the fob ) leave it for a couple of minutes and restart and it cleared.I do not do a great deal of miles so I steer clear of cheaper fuel and use bp  ultimate or similar the extra mileage I get out weighs the price. Good luck Alan

Hello,

just a quick one so my dpf light just came up the main problem I have with it that Iv just spent over £500 for replacing battery and alternator, and the lads from garage after dropping my car off said something about clearing the dpf light and taking car for a longer ride.

so I guess the light must of shown on them. Now they advising that it is very expensive to change the filter.

Welcome to the club, Kamil.

The diesel engine in your car does need a long run about once a month --  about 20 minutes keeping over 45 mpg, or putting the car into third gear to keep the Revs higher.

You should also use premium fuel and you can also give the engine an additive [I use Millers Eco plus Diesel] every time you fill up.  I have never had a problem with my S type with the V6 2.7 diesel.

Regards,

Peter.

I had the red DPF full message appear, telling me to visit the dealer. I took Captain Allan’s advice given above in this conversation. My XF had entered limp mode. I took it on a 70 mile drive on the A38, trying to keep the revs as high as possible. The warning light stayed on for the whole journey but, when I switched off the engine on my return and left it for 10 minutes, the car was fine again and had returned to normal performance. Thanks for the tip!!

When I picked up my xf in Coventry and was driving home on the motorway the dpf Amber light came on then red restricted performance.

The next day I added fuel and a good quality dpf cleaner,drove the car to force regeneration and the warning light went out, performance returned and that was a month ago,no issues since.

I add dpf cleaner once a month now.

So it's still ok to drive with the RED warning? I'm stuck at work thinking I have to walk home. There is a motorway near here i could give it a run on?

Thank you

Hi, new to the club. My xf is showing amber dpf is full. Going to try the advice and whizz down the m5 and back. Let you know how if it clears. Fingers crossed.

Welcome to the club, Kev.

I have had the same with my S Type and done the same on the A 38.  I would advise a steady run on something between 45mph and 60 mph.

Let us know how it goes.

Regards,

Peter.

Just got back. 15 mins at steady 70mph and the dpf warning went. Will have to start going for a run more often. Going to try the additive.

I have the pleasure of driving my XF along the M4 and M5 for approx 130 miles each way, regularly to collect my children and feel that this keeps my DPF in good order.

However, I was always under the impression that a car should rev at around 2500 to give the exhaust and DPF system a good blow out, my XF will do 2000 at 90MPH and although I would love to go considerably faster, I cant get the car to sit steadily at 2500 rpm.  If I do 70mph the car sits at approx 1800 RPM.

I have tried using the paddles on the motorway, but after a few miles the car naturally reverts to automatic mode. Is there a way of turning this off?

Hi Carl,

Giving the exhaust system some revs you will find that a diesels lower revs than a petrol engine.   My S Type 2.7 Diesel gives me 2,100revs f0r 70 mph, while my X Type 2.5 Petrol used to give me over 3,500 revs for 70 mph.

Regards

Peter

Hi Carl,

Do you have the option of putting the transmission into "S" mode? If you do, then you can use the paddles to select the gear you want and it won't be overridden after a while like it does in "D". You do need to be aware of the need to do all gearchanges youself though!

Cheers,
Jon

Hi all,

Re XF 3.0 V6 diesel.

Thanks for the advice on this thread. Having a DPF full, consult handbook message and following the handbook advice of a constant speed long run which failed to fix the problem. I then tried the sport mode 3rd gear 3500 revs method above on a 40 min blast down the M50 and back. The following morning,  its all fixed.

Guess I'm going to have to find some excuses for a few longer trips.

Hi everyone - new here although by no means new to the "joys" of owning a Jaguar...  As I was driving last week the red "DPF Full - Visit Dealer" message appeared and the vehicle entered restricted mode.  I drove it home on the motorway using paddle shift to overide the automatic gearbox but it didn't seem to make any difference.  I called a local independent JLR specialist and they said that in most cases, this problem can be fixed by cleaning the DPF and then doing some sort of computer magic to clear the error as long as it's looked at straight away (i.e. don't drive it around for weeks and months with the light on).  However they did say that as far as they were aware, once the red DPF full message came on, you couldn't get rid of it by forcing the car to regenerate the DPF and that if you took it to a JLR main dealer, they would probably tell you that it needed replacing.  So I booked it in for a check and dropped it off this morning, stopping on the way to put a bit of fuel in as it was getting a little close to the 50 mile range.  I put just over a quarter of a tank of Shell V Power Diesel (anyone outside the UK, that's a premium fuel) and when I started the engine the DPF Full warning had gone, performance restrictions had gone although the EMS light remained active.  I left it with the garage as planned, explained what had happened and they were a bit surprised the error had cleared - but I guess we all learn new things every day.  They're going ahead with diagnostics and I will let you all know the results and any work that they do to fix/correct the issue.

As well as that, their advice for good maintenance of the DPF system however is similar to what's been said here:

  • Don't use supermarket diesel
  • Use Premium fuel if you can
  • Use things like Millers Additive in your fuel
  • Give the engine regular motorway journies

Sorry if that's teaching anyone to suck eggs but that's a complete run down of what has happened so far

Picked up the car and there was thankfully nothing seriously wrong with it.  The garage had simply done a clean and regeneration on the DPF;  the report said that there was 57 grams of soot in the DPF and there should be less than 7.  But it's clean now, didn't require a replacement DPF and with a better care regimen it shouldn't happen again.
