Thanks, I'll look out for that. I've also found a garage in Blackpool that does off-vehicle DPF revamps too, and quotes around £300. They stated that it tends to happen mostly on the 3.0d engine at around 75-80k. Other people seem to have paid up to £600 so it sounds quite reasonable, should it ever be required. 

Yes that seems about right. Mine is a 3 liter and around that mileage. Wish I had known this when I bought it, I could have been using additive which might have avoided a fairly expensive repair.

Hi all,

So, having just lavished £1500 on a service on my (new to me) 2014 XF I then got the dreaded amber DPF (Diesel Particulate filter) warning less than a week later.

In my case it was  Amber warning saying 'DPF Full' but not the Red warning which is apparently worse.

This car is new to me and despite having a 2008 diesel engined BMW I was blissfully unaware of the DPF debacle until this happened as my 2008 car hasn't been castrated with a DPF.

I should be clear here that this is an industry problem affecting most 2009 diesel cars and is not confined to Jaguar

So having then read an awful lot online about this it seems in summary that the DPF is a device imposed upon all diesel engined cars from 2009 by a witless government in a knee jerk reaction to climate change in response to European Legislation (and subsequently implemented in a similar half arsed fashion by most car makers).

So, In my case I made a point of not using the car until last weekend (i used the dirtier BMW instead). I had a good run lined up (50 miles each way) and my warning cleared about 45mins into the journey and hasnt come back on since however I have absolutely no idea of the state that my DPF is in which seems like something I really should be able to view on the console screen as it's clearly quite a relevant item.

Because I have no idea of DPF state I have booked car in to my local Jag specialist who tells me that he can see the current DPF level and can also initiate a clean (which seems to involve him driving it round the M25 in the early hours while his laptop is connected to the ECU in my car telling him what speed to drive at) as he runs through a 'forced clean' process.

I would just like to get a feel for what you other XF owners have experienced

If you have a solution please share it!

If you are also new to the DPF problem then I hope this topic will grow to help us all out!

I have a 3 litre XF. I initially experienced the yellow warning light after I had owned the (second hand) vehicle for abut 4 month and it advised me to take the vehicle for a drive at at least 50mph for (i think) 20 minutes. This seemed to work. Then about 2 months ago (after another 8 months) i had just driven 160 miles on the motorway at performance Jag speeds and had pulled onto an A road when I got the red triangle of death. I pulled into a local cafe for a drink and t put some ad blue in (which I thought was the problem) and everything seemed to be cleared. The a couple of weeks later I got a yellow engine light. having taken the car into my local Jag specialist, it transpired that engine omissions had backed up and blown the (I think he said) manifold. This would cost over £1K to repair. The guy said that this was a common problem particularly where the car is used for short distances and stop start  style of driving. He also advised that after he had fixed the problem, I would need to go to a specialist for them to try and clear the DPF. What a total pain in the rear. he also advised that the car would be O.K to use short term until the repair was carried out but I would get the red triangle of death (restricted performance) at regular intervals. This has proved to be the case.

As an interim measure I have started to use DPF fuel additive which (early doors) seems to be working a treat as performance has picked up, the car seems to using less fuel (it was a very thirsty beast, now not so much) and performance has picked up so well worth the £7 per bottle.

MOT is due in about 6 weeks so I plan to have that and the repair done at the same time. Instructions on the bottle advise that I need to use on bottle of additive in a full tank about every 3K miles. If this stops the problem from re-occurring then that seems like a good buy for me.

Thanks for the heads up. Speaking personally, I try to avoid eBay. Whilst there are some good deals to be had in there, I have discovered at my cost that there are a sizable number of sharks and scammers lurking in there. The so called buyers protection is also not what it purports to be and has a tendency to be worse than useless.

I bought my XF 2.2 just short of 6 months ago. The dealer (Citroen dealership) had tried to rectify a problem on the dif but whatever they did, didn't work culminating in a very loud bang whilst I was bomming down the motorway and an intense grinding noise thereafter. Fortunately, the Jag was only 1:3 into its warranty and the dealer fitted a new dif. All now seems well with this issue 5 months on (but I'm not holding my breath).

There is however a further repetitive fault. If I am doing a lot of stop / start driving, the engine gets rather warm (hot). When this happens performance drops through the floor and I have to drive with the paddles and rev high before changing gear to avoid a desperate limp. if I let The jag cool for a few hours, performance returns until things get hot again, when the fault becomes apparent again.

The dealer (perhaps being coy) didn't have a clue what the problem is. They did a test drive and said that they couldn't find a fault (a likely story). Over winter, the problem didn't show up quite as much but now that the weather is changing, the fault is becoming more prevalent.

Anybody got any ideas what the problem is and what the solution may be?

many thanks and B.W.
