XJ Diesel DPF Issue - Outraged
Discussion
Is anyone here aware of a DPF issue specifically relating to the V6 3.0 in the XJ (same engine in XF, F Pace and various Land/Range Rovers of course)?
Mine is a 2016, 25k miles, full history and meticulously driven for the last 10k miles by me in respect of the annoying 'diesel' procedures, ie, relatively few short trips, mostly high speed ones, to allow the DPF regeneration to take place.
I am not a fan of diesels generally but have had many reliable ones as company cars from BMW and Merc. Never had any DPF warning lights ever until now with the Jag (my own)
On a local trip it flashed up the Amber warning to tell me to get on a motorway to clear the DPF, in spite of a few days earlier doing a 400 mile round-trip on motorways. By chance I was near the top of the M3 so jumped on it and dropped a gear or 2. Within 2 minutes the warning went Red so I limped home and got it towed to local Jag dealer in Guildford.
Their diagnostics (which we have to pay for these days - another bugbear) resulted in a comment to me and my Motoreasy warranty co that the DPF and Throttle body needed replacing due to carbon build up. Over £3000 to fix. Of course the warranty doesn't include carbon build up
What a complete waste of time that diagnosis is. Telling me there is carbon build up isn't the cause of the problem it's the outcome.
There has to be a specific fault somewhere in the system to allow this to happen, yet all they can state is a vague description of the current state of the parts without telling me why except to imply it is driving style which cannot justifiably be true given the way I have gone out of my way to avoid this. I use another car for most short trips. Besides, why was I only given 2 minutes of Amber warning before going Red.
The technician is even claiming it is too bad to be possible to clean!! Boll**ks!! Every specialist I have spoken to has said they think it can. One even told me that the same dealership told them they sell a lot of new throttle bodies. This would suggest these are regularly faulty, causing a fueling issue.
Naturally I am telling the dealership this isn't good enough and I expect Jaguar to pay for it (and to tell me the real problem). I have also contacted Jaguar UK myself.
Incidentally, earlier this year they gave it a free early oil change due to oil contamination, which suggests a fueling issue also.
Rant over but has anyone else had a similar experience with this engine? Without doubt this will be my last diesel from the JLR group, possibly from any manufacturer, given the expense it appears so many people incur whilst trying to save money via diesel.

Thanks for that. Immediately found a useful article that will provide good ammo to hit jaguar with. It was stated in that thread that the DPF on this car (and a RRS) is mounted too far down the exhaust for Regens to get enough heat in the DPF to burn off excess soot. Just what I needed, some info to tell them it is a design flaw. My wife is a lawyer so I will be threatening them with a messy and expensive legal action aside from bad mouthing on forums
Here's the thing, yes it is the 300bhp, and I do always carry out due diligence but nothing seemed to show up 2 years ago. Even now it doesn't easily come up in searches. So it's not as 'well known' as thought and certainly wasn't 2 years ago.
But even if there was more evidence at the time I can guarantee that whatever car you search for info on regarding reliability or known issues you will find examples of people having a bad experience. It's the nature of the beast. Search for something specific on the internet and somewhere, someone will have something to say. That's partly how 'fake news' works. The search engines and social media have algorithms that target you based on what it is you look for. Worked for Brexit, worked for Trump and so on.
So what I am saying is, nothing of note came up about this car of note to put me off which is is probably due to the relatively small numbers of Jags sold when compared with doing similar searches on BMWs or Mercs, etc, that have sold in significantly larger numbers. So they might seem terrible cars but there are far more of them meaning the odds of failures are greater.
I am am already going down the goodwill route but focusing on the fact that, if I am paying for a diagnosis, guess what, I want a diagnosis. Not some vague report stating carbon build up. I could have told them that was the outcome.
If I can get something more specific about a fault in the throttle body function the warranty company will pay up whereas they won't for a vague description about carbon build-up.
From conversations with numerous DPF cleaning specialists and from reading stuff here and on the JagInfo forum it would appear any one of them can give me a more specific diagnosis than 'carbon build up'.
So I accept I will be lucky to get much out of Jaguar and if it's anything it might still be cheaper to go to an Indy to replace the throttle body which I am concluding is the original faulty part and have the DPF flushed
I am in Weybridge, Surrey, if anyone knows of any good specialists near me. I have used XJ Motors who are good and there are several mobile DPF cleaners but other suggestions very welcome
It's a fabulous car and even my dislike of diesels didn't put me off but I won't buy another diesel.

One other thing to bear in mind is that the best threat is often that of poor reviews in social media and the internet generally.
I know someone who bought a new Volvo that had major problems. Even though bought new the dealer and manufacturer kept fobbing him off until they realised how much bad publicity he was giving them online. They eventually gave him a full refund.
This is also part of my approach with them. Again, will probably be fruitless, but worth a try

Update:
Jaguar have offered a 40% goodwill contribution.
I will probably take the car to my local Indy specialist XJ Motor Services to remove the DPF and I will take it to a specialist cleaning company and get that part done for about £150 as it will still be considerably cheaper than the extortionate amount Jaguar want for a new one even with a 40% deduction.

I have considered that but the ones that I would trust to remap my car don't also cut out the DPF. I would have to get that done prior.
And overall the cost isn't any lower than getting it removed, cleaned and refitted. For the time I will keep the car that would be preferable.
I'd also not be happy about selling a car with a 'mod' like this without disclosing it and that might rule out some potential buyers.

Thought I would give an update for general info
I rejected the jag offer of 40% off as it was far cheaper to get my local Indy to remove the DPF and take to Maidenhead specialists for a thorough bench clean
They showed it was only 60 5% ish blocked so the Jag's onboard and dealer diagnostics are clearly crap to say ti was totally blocked. They got it to 99% flow rate so it's back on the car. Then took it back to Jag for the throttle body but all of a sudden they relented and opted to clean it instead of replace. They did that for just £80+VAT which was very fair so they probably wanted to see the back of me
Total outlay less than £470 for the lot
Trouble is that although the same shouldn't happen for another 4-5 years or 25k miles it has put me off bothering with it. I use my 14 year old XK most of the time now and will sell the XJ. Shame as it's a cracking car and if I could find a V8 2016+ car for similar money would go for that but with so many great cars out there, probably not. Thinking AMG C class, another BMW X6M like I had before, a Mustang or even a Kia Stinger V6 twin turbo which really impressed me especially for the money
