Jag XF - how bad could it be?

[JOldcastle]

Hi,

I'm tempted by an XF, probably somewhere about 2016-2018. Obviously the reputation of some of the JLR stuff is patchy at best, although I'm not sure how much of that is from specific issues rather than the whole range.

I've heard enough tales of woe regarding the diesel Ingeniums to want to stay well clear, which means I'm considering the AJ V6 3.0d v6, or the petrol 25t (which I think is an Ingenium too).

Does anyone have an idea of:

- Are there issues with the 3.0d as well, or are those generally a bit more robust?
- Are the petrol ingeniums as bad as the diesels?
- Should I run away completely?

Thanks!

I work for JLR on the supply side and even though they drive great I wouldn't touch an Ingenium engined car petrol or diesel with a barge pole.

Mate had the 2.0d as a company car for 4 years with zero issues.

Think it was a 66 reg.

Did big mileage in it as well so they aren't all crap (However, having the knowledge it wasn't his car obviously helped with any anxiety)

Would recommend the V6 petrol,or an earlier xfr

As above, dont touch the ingenium engines.

So the 3.0 diesel and petrol are fine.
This eliminates a huge amount of bork factor, leaving you with a similar number of potential problems to most other alternative cars

I heard rumours the 3.0 diesels suffered from snapping crankshafts.

That might be caused by the oil dilution issues.

If that is the same V6 as fitted to the disco 4 then it is caused by undersized bearings and poor manufacturing/QC of the cranks.

So that will be a separate issue.

There is a graveyard of 3 litre engines with snapped cranks up in Scotland according to a previous thread on here.

My son has the 3.0l diesel and that also had an issue with water ingress damaging the ECU, which he was told was a common problem. I think he said it was a plastic cooling pipe that perished and water leaked onto it.

That cost him about £1200 to replace.

I would stick with petrol, JLR seem to have trouble with diesel engines.

We had an X350 Jag with the diesel and it was great. Owned it new from 2006 and sold it 2020. Had a blocked DPF but once cleared that was all. Did over 200k miles in it. The 2.7 is the lesser stroked 3.0.

That would be the earlier X250 model.

2013 on a 13 plate.

That was caused by water from the screen washer pump, fixed in 2014. There is a service bulletin for this.

That was the problem.

I knew he said water ingress//leaking, but not sure from where.

They're pretty lovely places to be; certainly the 3.0d has a couple of known faults - the crankshaft bearings being one; but it seems in the Jaguar application it's far less likely to happen than in the Discovery. Much debate seems to exist on 'why', but either way, it's a win for you!

Otherwise, very comfortable place to spend a lot of time. Definitely get the uprated Meridian sound - as with most premium saloons, the base stereo is a bit clock radio, but the branded one has some heft to it.

Isn't this due to the oil becoming diluted with diesel due to failed DPF regens?

The 3.0d is a good steer as is the V6 petrol.

Ballsy move, whatever the engine

I think the main problems with these engines are short journeys, stop/start and services intervals.
I do long journeys, turn off stop/start and service every 12/13000 miles.
Had the car just over year and 29000 miles and no problem, now on nearly 80000 miles.
Although before I had it service was long intervals and I think possible a large problem occurred , don't know what though!
