My brother MAY possibly be changing his car this year.

He likes the look of the XF - especially the interiors - and is considering a 2.7 - however a 3.0 may work out better due to the cheaper road tax*.

So im wondering if the good people of this forum could give me the lowdown on just how good - or bad reliability of these are.

Have read tales of woe on the 2.7 both here and elsewhere - but what im wondering is - are these tales of woe - isolated incidents - or are they indicative of widespread reliability issues.

Hes well aware that Jags don't always have the best reputation - so be all means be brutally honest

Thanks guys

  • the irish road tax system is worthy of a big massive post on its own

I'm interested in this topic too, particularly any problems with the 3.0.

I'm still thinking about getting a current-gen XJ. The vast majority of used XJs in the UK are 3.0 diesel, so although I'm not a big fan of diesel generally, I probably need to go for it in order to have a reasonable choice of colour/spec.

Try to avoid the 2.7, the 3.0 D is more reliable, stronger and sounds a hell of a lot nicer to boot.

I think the 3.0 was updated from the 2.7 to add a way of securing the bearings for the crankshaft. otherwise I think the engine is just an updated 2.7 with extra capacity, the TDV8 is based on it also.

There are a lot of 2.7's out there in a wide variety of PSA/LR/Jag cars, and you only generally hear about the ones that fail, rather than the ones that are still running fine at x,000 Miles....

Having said that I'd go for the 3.0 diesel if I had the choice again (if I couldnt man maths a V8 Petrol)

No problems with my 3.0D. The only thing to fail on my XF has been an am tuner module & that was replaced under warranty.

No problems with the actual engine of my 2010 XF 3.0 Diesel S but did have a cracked seal on the DPF which caused it to go into limp mode but since that was fixed under warranty there have been no other problems. Some 2.7 engines had turbo actuator problems but I imagine all those would have been fixed by now.

I've had a 2.7d Xf (2008 model) which I bought in 2012 with just under 95k on the clock and a full Jag service history.

It's been very reliable for me with just standard servicing needed and a diff seal being replaced at the last service.

Until this weekend......when the DSC not available warning came on.

I've had it checked out by local specialist today and they are going to take the car in for further investigation on Thursday. The guy who runs the shop said that he's seeing a few wiring issues on the older cars now. So that might be something worth bearing in mind.

The main gripe with the car is the Sat Nav. It is possibly the worst I have ever used, the routing is awful, to the point I will only use it for finding a specific location when I'm within a couple of miles but even then prefer to use TomTom or Waze on my mobile phone. If you have an iPhone and want to dock it, check that the car has the iPhone connector and the right cable to work with your phone.

The other thing to bear in mind is the type of journeys you do, if you are only doing short trips then a diesel is probably not suitable as the DPF will not get warm enough and may get blocked requiring a decent run out to regenerate. This is not Jag specific but is an issue with all the modern diesels that have DPFs fitted.

I don't think they are any worse for reliability than any other modern car, providing you pick one that has been looked after and serviced correctly.

My 3.0D is currently at around 40k miles, no problems with the engine what so ever.

Generally speaking, the car is very solid.

Regarding the 2.7 vs. 3.0, I guess it is always a good idea to avoid the first generation of any new model. No matter what manufacturer. It seems to take them ~3 years to find the common niggles and alter the production line.

We got a fleet of them at work (Police) and really looked forward to their arrival.

A few years in and we're not ordering anymore. Sadly, they haven't been reliable enough. The facelift improved things a touch, but we can't afford to lose cars as regularly as we do with the Jags.

Can you give some details of the things that went wrong? Also, was this the 2.7 or 3.0?

Second.

Individual stories are rarely representative, but a fleet of the same cars is actually telling a lot about common problems. Also, how many cars were in the fleet?

Off the top of my head we had 8 (along with Audi A4s and BMW 5 series). The cars do around 80k/yr and are used 24/7.

The 2.7 diesels were horrendous and we constant engine problems including a number of replacement units. They constantly broke down. They had a habit of starting, driving to a job and then they refused to restart. It got a bit tedious having to call for recovery.

The facelift ones have been more reliable, but still suffer brake and electrical issues. I can't really be more specific because when they break, they just get sent to workshops and then reappear.

They do lead a hard life, but so do the Audi's and BMWs and they do not suffer anywhere near the same problems. The most telling point is that the fleet manager isn't ordering any more. It's a shame because they have real road presence and drive well when they work, but they are a tool of the job and we need to have confidence in our cars.

In contrast, I've had exceptional reliability from both my XFS's (3.0d 2010 and a facelifted 2012, both bought new) and have just bought a new XFR.

I have to say, My experience is not based on long term reliability, I chopped the first one in with 32k on it and the second with 11k, no reason for the changes other than going to the facelift from the first car and then the dealer of offering me a deal I couldn't refuse on the XFR smile

I had a 5 series (F10) BMW and had so much trouble with it, that I got rid at 6 months old, my wife also had many issues with her E93 BMW

I can't comment on the early 2.7's but the pick of the range has to be the 3.0d's even dare I say it, frugal for such an engine

Spoken at length with a resepcted Jag Specialist in Doncaster last week and he commented that he was now seeing 3.0d engine Jags failing in the same way that the 2.7d have been known to.

Buying a 3.0d does not guarantee you reliabillity

avoid jaguar diesel 2.7 models as there horrendous. I currently have one and it's a nightmare. restricted performance is a problem if you mostly drive in city as dpf is linked to city driving hence restricted performance. motorway driving is best. then you have air suspension faults. my bill is 8,000 pounds and counting. go for 3 ltr diesel, manual is best as it's cheaper to replace clutch than auto gearbox. how ever I think 3 ltr diesels are automatic only.

Au contraire...

I had the 2.7D engine in an S-Type for 60K miles and it was brilliant. Faultless reliable performance.

Then I had the 3.0D in an XF and it was plagued with 'restricted performance' and sensor failures.


Maybe it's an XF thing? The 'sport' mode and kickdown were definitely peculiar.
