High mileage modern diesel's Problems?

I think that's probably coincidence. Modern diesels certianly have their problems, but they don't seem to be mileage/wear issues. Wondered what the larger picture is as mine is on nearly 70 thou
If I was buying a modern car at ~100k miles I'd be more concerned about the state of things like suspension consumable than the engine.
Just relax, if something is going to go wrong then it will. Just accept you may have to spend on a car to keep it safe and reliable.
I just bought a 80k mileage petrol Audi. It's 8 years old and has been serviced every year.
Since buying it I've spent a bit already. First I upgraded to Audi wheels I like, then I've put on a fresh set of quality tyres (was not expecting this until next year, but I hit a curb damaging a tyre so just bit the bullet), and I've given her a major service. Oh and the day I had it booked in for Its service the original 8 year old battery decided to die, that was hundred quid to replace.
So far then I've spent
Battery = 100
Service = 190
Tyres = 356
The only unexpected bit of maintenance was the battery replacement, but I'm glad it went now and not middle of winter.
I fully expect this car to be reliable now up until the day the fly wheel packs in. That could be years away. Either way why stress over it?

As said before don't panic... I've had company cars mostly from VW or ford diesels and a Seat. All went up to 120k in 4 years and gave no troubles. It's a mix of luck, usage and maintanence. All mine have been motorway miles so probably helped reliability. None of them ever used supermarket fuels either but that's a different argument!
I had an 407 with the 136hp hdi 2.0 euro V emissions compliant engine as used by for as well.
Serviced to schedule
At 90k had new turbo,
Dmf was questionable, no vibration but clutch making major graunching noise
dpf fine
Main problem, it had a niggly loss of turbo boost, that I could not find the problem, and a full diagnostic would have cost as much as the car was worth so dumped.
Nothing really wrong with the engine, just the emissions crap stuck all over it.

As above it depends on use rather than millage, no motorway use usually meens DPF issues, EGR and blocked inlet runners, worn clutch and DMF, most vehicals i see with the above issues are approaching 120K and rarely see motorways if ever, women drivers and older people get the same issues earlyer, IME youngish men tend to thrash them more and that helps beleive it or not.
last Mondeo covered north of 300k without any issues of note,
original clutch dmf injectors turbo etc etc. driven hard every day and used as a taxi so not exactly an easy life.
top tips
drive it hard regularly. albeit after letting it get up to temp and cool down properly
don't use cheap oil.

2nd engine in 09 octavia 1.9 pd has been pretty good- From 62-183k miles. Variable turbo vanes started sticking due to carbon build up on the turbo causing limp home mode activation now on a lower annual mileage. Hopefully fuel and air side cleaners will have sorted or the turbo will need stripping/ cleaning.
Unfortunately first one was an early BXE and did the all to well recognised piston through block trick. VAG completely deny the issue 2 years/35k miles later gearbox failed, almost certainly related to engine detonation. Dual mass flywheel was on the way out at 100k too, replaced with gearbox.
So at 2.5 yrs/62k miles an 8k car needed a 6k new engine (was owned by my former company then). At 5years/100k miles a 5k car required 3k of gearbox, dmf etc.
And this was an older 'reliable' diesel without a dpf and driven decent distances for 20-40k a year...
Avoiding VAG like the plague and trying Ford (Mondeo mk4) & hoping they're as good as many people say (after an earlier focus dog- turbo, 4 alternators, fuel pump, ecu, suspension collapse all in 75k)...

My 2005 320d has now 182k bought it with 58k. Apart from normal consumables like brakes, tyres and suspension components that where worn. Only thing needed was high pressure fuel pump. Still on original turbo, clutch, etc.
Quite happy with it overall, problem with my car is not the engine its a little rust spots starting to appear and brake lines will need replacing soon as it shows rust. About £500 for that when I come round to do it.
I think I will keep it until it dies really.

I have had three "modern" Citroen diesels (so same design of engine as Peugeot, Ford, Jaguar and Land Rover). The first two both made it to around 95k without any engine problems. The current one has 116k and whilst it has had a few things go wrong, none of its faults have been due to it being a modern diesel.
Maybe I've been lucky though.
Among friends and family, an Alfa had a sticking EGR valve, Vauxhalls had everything go wrong, a Toyota needed the whole engine replacing, and three people I know with VW/Audi diesels have gone back to petrol.

I've seen many low mileage diesels written off due to electronic failure of an expensive component or more often a fault that could not be diagnosed. We run a number of older (2001-2004) Peugeot 406 hdi all around the 200k mark and all mostly original. We're operating on the basis that any early catastrophic failures if they haven't occurred already probably aren't going to. We're four cars and five years in now so I'll let you know how it turns out...
[quote=spikeyhead]My Saab 0-3 diesel has 210k miles on it, had a DMF about 100k ago, snapped a cambelt at 120k but that was because I presumed the leasing company had changed it when due at 72k miles but they hadn't.
The engine is likely to get it's eight oil change next weekend.[/quoted
I suspect that leasing companies do the absolute minimum. eg: friend had a lease 320d coupe, with extended services ( yes, the car tells you but that only affects low mileage users) . So, he had a service at 20k, replaced tyres soon after, original spec and chopped it in at 37k. It would then appear as used approved at a premium main dealer price. The attention it had received was minimal.

My current 2011 diesel has done 291k to date, and my previous 2 both did 312k.
All serviced as per mfg recommendations, and none of them had any major issues.
The current car had a new water pump at 210k ish miles, cost £340, and that is really about it.
No DPF problems, no injector problems, no fuel pump problems, no turbo problems, no electrical problems, no gearbox problems.
Damn unreliable these modern diesels.
