Why are modern diesels so troublesome, by a mechanic.

[jongood]

An interesting take, if you're stuck for time just second half.

 

[Roger S]

That was interesting and makes a lot of sense. The Citroen/Peugeot XUD was a superb engine and would last with out issue for 100s of thousand miles, now with the Ingenium engine used in a few modern cars you can get as low as 50,000 miles before you have to start spending lots of money, progress !

 

[DandJ]

He states 'fit for purpose for everybody..' They never were. They were often mis-sold by sales bods...they should have been 'reserved' for those doing 15k a year rather than selling small Fiestas or 106s to Mrs Miggins who only does 2k a year and invariably drives in and around town or city all the time. If sold properly, perhaps they'd not be so demonised now ?

As a Heavy Diesel Mechanic, I couldn't agree more and that is the reason I searched for a long time before buying my S/H Murvi on the 2007 Fiat Ducato LWB chassis.
It has the 2.3 multijet engine with EGR etc BUT legally does not require any DPF, CAT or AdBlue.

Yes, it does restrict me from driving through some Cities but most of them, both here and abroad, I have driven through already and these days are better seen from the top of a Double Decker Bus with someone else driving and free with my OAP BusPass.

(In a few years time when I reach 85, it might be up for sale, so the wisest of you, will place your deposit with me NOW!
Who knows what the future holds, you might get it early? )

That video makes me feel smug about the Ford Duratorq TDCi diesel in my 2007 Hobby T500! Like most people I lust after something brand new but the more I read about Ford's wet belt problems and Ducatos going into limp mode the more I feel I should stick with what I got!

If/when I upgrade I shall have to think carefully about power unit reliability given my style of use. My principle ambition is to spend time in Europe. That means a circa 275 mile drive to Channel ports. That is the sort of use diesels are meant for but much of the time the van sits on my drive doing nothing. That is the opposite of what works best for the engine.

So what Euro 6 diesel units are rated as reliable by Funsters?

Maybe I should look more closely at Euro 5 despite Crit Air limitations? Euro 5 and an auto box might be a nice compromise. Hmnn!

Is it a case of if they build something to last, who buys new?
The old film " man in a white suit" spings to mind.

 

[funflair]

OK diesels have changed since our old 2400cc 4 pot in a Mercedes 123 series, I say changed and in many ways changed for the better as they are more economical, quieter, more powerful and cleaner of course, but yes those improvements especially in emissions come at a cost of added tech and systems which are not always reliable, it's OK pointing out these various failings but in reality what choice do we have? smaller cars could be petrol, hybrid or even battery but the bigger stuff still really needs the grunt of a diesel engine, I am sure hybrid would work on truck chassis but I don't see much development in that area so yes we are stuck with diesel so we either all buy up the older stuff or we take the risk me? I am living on the edge with a Euro 6

 

[Pausim]

He says some manufacturers have made the transition to cleaner diesels without losing reliability. As far as I am concerned it is some manufacturers that are failing us not the Euro standards that are trying to reduce pollution. NOX is bad for our health and I would rather not have to breathe it.

 

[martin2603]

I’m going to stick with my Euro 6 non adblue Ducato . Have so many problems with the adblue in the HGV , just drives me to distraction .

 

[Hedgewitch]

What an excellent little video, and such a pleasure to hear someone talking straight to camera like that - no waffle, no filler, just pure information and details.

At around 10:00 he mentions the current VW engine as "not being one of the best" and TBH, what VW have done to the T6 engine is half the reason I've sold my Transporter. Too complicated, too much going on in the ECU, and when you live two hours from a VW Commercial dealer, to ruddy inconvenient.

Thanks for sharing that jongood.

Yes I had a beautiful Peugeot meridian 1.9D estate, never out a foot wrong, used to service it myself, it had a bladder to pump fuel through. Over 150,000 on it sweet as a nut.
A nutter in a Land Rover crashing into it wrote it off

The point is though that the previous generation XUDs etc were ok for use as a shopping car because they were simple, compression and fuel and away they went.

Shame he doesnt say which ones. Definitely not Land Rover, Ford, Mercedes, Psa etc. Fiat engines are mostly ok but gearboxes are terrible.

I had a 2003 Seat Arosa 1.4tdi brilliant little car (same as the VW Lupo)
But eventually it kept going into limp mode and nobody knew why.
I buy petrol cars now, my 1000cc Volkswagen UP wouldn't pull a hen off it's nest.. but It's reliable and I like it

 

[Spriddler]

That's one reason that I'm more than happy with my 1998 m/h on a VW T4 base. No ECU, DGR, AdBlu, Turbo or Cat converter and it has been faultless and never even had an Advisory during the 12 years that I've had it.
The hab dep't is well built with solid wood and all the domestic equipment and uncomplicated electrical system (no 'Anxiety Panel' ) has been totally reliable. It's not quick, but I'm retired, only tour abroad, never use motorways and rarely have a 'destination' in mind.
Pocket money motorhoming.


And my motorbikes are 'Historic' category so no VED or MOT's required'.

 

[nicholsong]

I am very happy with our 2002 Fiat 2.8jtd. A basic diesel, which any mechanic worth his salt can maintain without gizmos.

I did have it re-mapped, not because of the engine but to get a better match between engine and the high-ratio 5th gear. I could have fitted a different gear but the engine had the torque available.

We do not want to go into cities, so emissions zones are not a problem, now that I do not live in my house in London. I feel little guilt about emissions as it is my only vehicle and does 4,000 miles a year. Some people buying often on the internet could cause equal mileage and emissions.

MOT equivalent is also not a problem if it stays on Polish registration as it is exempt, and no road tax in Poland for any vehicle.

The Merc engine on my old boat was built in 1978 and is still running 46 years later, so I hope my 22 year 2.8jtd will do the same. I doubt they have emissions control in Hell, so maybe I will be OK taking it with me.

Im gonna hang on to my 3.0L euro5 as long as I can until the money runs out

So is 2002 Fiat exempt from MOT's in Poland?
I thought, if it stayed in UK over a certain length of time, it had to be re-register here?
Is that wrong?

Google mercedes nox sensor and have a read? Apparently they just go without warning and its a dealer job to source and program the new one. Like the silly gearbox servo on the 7g transmissions.

 

[BikerGraham]

He did which really surprised me as Mercedes Adblue reliability is one of the worst.

 

[cyberyacht]

My 150BHP 2.3 is Euro 5 and qualifies for a Critair 2. so I'm 'not bovvered'

 

[ontheroadagain]

There are lots of 20 year old motorhomes on the road still running great and proving to be very reliable. I do sometimes wonder if a new 2024/25 motorhome will still be on the road in 20 years (assuming they aren’t forced off the road by environmental legislation). Our current motorhome has been back to the garage more times than any other vehicle I have ever owned and it is only 3 years old. I just wish Toyota/Mazda/Honda would make a large van!

Hi to all, We have a VW lt35 mk2 lwb camper she has just gone through M.O.T with no advisory reg 2005. She is basic can but she does the job no problem.

Modern diesels are fantastic. The problem is that manufacturers keep creating ever more elaborate and expensive ways of stopping garages from sorting out simple issues

 

[Odd job]

I have recently bought a Nissan pick up truck. Had it for a few months and love it, but on the FB groups I've joined there are many tails of woe, often from newish vehicles. Some have had new engines, under warranty, at fewer than 50,000 miles. I still have a years warranty left, but I'm now worried enough to be willing to pay £875 a year for an extended warranty when it runs out. For a Yorkshire man that scary

HOW MUCH!

I've bought vehicles for less than that!
