Another XF 3.0 diesel blown engine (at 53,800 miles)

Keep us posted!

OP - does that price of £2.9k+vat include removal and refitting of the engine and all the ancillaries? i.e. a "drive in/drive out" price? Or is it just for the rebuild itself?

I have been looking at the 3.0 diesel XJs for some time - they are getting to be quite cheap, especially those with intergalactic mileage, but I am really nervous about owning a modern diesel with all of the problems we hear about (and let's be honest, JLR are not exactly dominating the reliability league tables). I understand that at the cheaper end of the market you have to have some appetite for risk, but I dread the thought of buying something and then paying thousands to rebuild the engine and then having it feel never quite right afterwards. Or being unable to find somewhere that does the job.

When I did some research a couple of years ago I could not find anyone that rebuilt the V6 diesels. The Jaguar specialists I spoke to said they didn't know anyone who did it and said that the only option would be a new or reconditioned unit from Jaguar, for much £££. Hence interested in this.

Yes that’s the whole job and because I’m local hat included vehicle pickup too. I won’t see it again until I get the car back clean valeted and running sweetly. That’s the plan. I’ll know in 3 weeks if it comes to fruition as hoped!!

What should happen when the oil gets too diluted is the ‘Service Required’ messages comes on in the instrument cluster. That’s the only warning you’ll get and if that happens before your service is due then you need to take it somewhere that can check the oil dilution levels and the number of demanded regenerations, incomplete regenerations etc.

Very common to happen to low mileage, town driven 3.0Ls

has been happening since the 2.7 was launched. These engines are just not comfortable driving around town with a DPF fitted and an incomplete regen dumps diesel into the oil.

So in just twenty years Jaguar have gone from manufacturing cars with the expectation of a quarter of a million miles or more life from the engine to it being commonly accepted now that a engine with perhaps a fifth of that mileage is quite likely to spectacularly lunch itself?

This will not do...

The problem is that a huge majority of them were mis-sold to customers. Sales staff should have been asking what the use patterns of the cars would be before they were sold and for the people who just drive short distances and around town they should have been clear that the engines were not appropriate. The problem was everyone jumped on the “ill have a Jag that does 50mpg” bandwagon and that meant nobody bought the petrol units and when they did they depreciated like a stone.

OP that quote of £2600 is that to be in a position with everything done and ready to drive out or is there further work?

I guessed that had something to do with it.

Still, I love the thought that versions with brick sthouse petrol engines rather than flaky diesels are the ones that depreciate like stones though...

Not all the Petrol engines have been great because, certainly in Europe, the diesel thing was so massive so it diverted R&D. The early v8 had its nikisil problems for a start and I wonder what the consequences of development of the new ingenium engines will be which are 50/50 Petrol and diesel just as the world is shunning one of the fuels.

Still we are going off track. Good luck with your rebuild OP

Hi craigm
£2.9k + vat (£3450) all inc ready to drive away. All behind well,. that’s the unproven theory, I’ll let you all know! Thanks for the good wishes....

[gduk0256]

Another question, although my sump diesel had some oil in it (yes, it was that way round, lucky not to have a runaway IED under the bonnet) I got no dash warning of any sort. Ideas?
Thanks

Thanks for that. There is a thread on another forum about this exact issue and so called “experts” are saying that’s only for a partial rebuild and quoting 15k etc etc. You know the usual no idea types. Good luck

[gduk0256]

Hi craigm
I know what you mean. This one is CS regrind, block skimmed, bores honed or lined, new (custom) main and big end bearings, timing kit (chains, belt tensioners, oil pump, pistons ceramic coated or replaced, rings, con-rods honed or replaced, cyl head(s) stripped, skimmed, appropriate size gaskets, new valves.
All new seals gaskets etc. Drive away smiling but checking oil level every 4hrs😱) Looks good on paper, let’s wait and see if the Old adage ‘...if it seems too good to be true....’ plays out. Before someone else says it! I’m hopeful though, so thanks again for interest and supportive good wishes.

I feel the pain. My XF lunched itself within 18 months and Jaguar bought it back off me

[Aletank]

So is the preventative maintenance to have the DPF removed ?
I remember a good few years back when looking through Autotrader at XJ's and there was alot with, new engines replaced by Jaguar under warranty, probably petrol engines at the time.

Those will have been the nikisil lined v8

Removing a DPF would solve it but with the big clamp down on diesels happening now that must become an MOT check and fail at some point.

[groomi]

This makes for scary reading as it's the first I have heard about the problem.

I have a 14 plate 3.0D Sportbrake which I am intending to keep at the end of the PCP in March as I can't find anything equivalent for the same sort of money and don't want to start another PCP.

I do a good mix of driving, so hopefully won't have any DPF problems, but this makes me nervous. I fell foul of the timing chain tensioner issue on my old X308 XJR, so am well aware that warranties are useless in such situations.

[gduk0256]

Indeed groomi
The JLR diesels seem particularly dpf error prone for some reason. Removing is not an option legally as I understand it. I may be wrong tho. Legislation has stated that from 2009 diesel vehicles must be fitted with this. So, to make this work, I'll need to drive nearly double my usual daily mileage once or twice a week to ensure complete dpf regeneration it would seem. Thus more emission of the nasty nanoparticles which the dpf doesn't remove. Imagine all the affected vehicles in the UK running excessive mileage, just to stop the engines from grinding to a halt...... Some government department got this all wrong (for a change!!)
I'm on a 100% renewable electricity deal.....there's only one way forward and that has to be away from the inFernal combustion engine. 😳 Ah well....
Still, need to get the xf back up and running. First priority. Lovely car but brand loyalty out the window!

I find using v power diesel really cuts back on regens, makes sense because in our old remapped seat it noticably smoked on hard acceleration but on v power it didnt at all so if there is less particulates the dpf has less work to do.
