That's all quite damning stuff. Surprised

It begs the question as to whether any diesel, and small diesels in particular, are really suitable for many drivers once you apply Euro 6 requirements.

Hi Supacat

You are correct regarding Euro 6 engines. the harsh reality is that for many people the vehicle is used primarily for the daily commute to work. In many parts of the country this can be a crawl to work rather that a drive to work.

So for that journey a petrol would be better in terms of lack of DPF filter, however how long will that last. Petrol have been Euro 4 for a while now so when will that change?

Not so relevant for now, but look at the areas that have LEZ zones or considering them in the future.

My wife has a very good car scheme and has had far more LR products than I (that and I hang on to mine rather than having to change every few years). One thing I had noticed regarding her last and current vehicle (both with DPF) is that the salesperson at the dealers 'mentions' the DPF but does not go into any detail of the pros and cons or even asking the consumer is a modern diesel the right engine choice for your lifestyle and commuting experience.

My wife's journey to work is 11 miles, this can take anywhere from 25 minutes to and hour and a half!!!

Because (and like most people here) have an understanding of the basic requirements of a DPF if we need to go somewhere on the weekend then a quick blast up the A3 makes me feel better. But for some people it is actually hard to get the car up to 60 miles an hour for a full 20 minutes without slowing down to a crawl at some point.

The danger is that even though the car will ask to be driven for that speed and time it may not always be possible.

And there lies the problem for the future, DPF's are great if you can drive accordingly, petrol Euro 4 will someday be outdated and banned from city centres and Electric is still not good enough if you want a direct replacement for you , your family, your lifestyle.

I'll keep my TD5 until our local council does something stupid and introduces an LEZ zone then extends it every year to make money, I mean save the planet.....

This was in LRM a couple of months back.

Thus is one of the main credibility issues that JLR has - lots of owners report issues, JLR buries it’s corporate head in the sand and then claims its the owner’s fault for not driving the car properly. SDv6 crank issue was the same, ICTP issues the same. They seem to hope that making ‘ Good will” payments to a few customers will solve the issue for everyone when actually all it gets them is a heap of bad publicity for being unsympathetic and a reputation for unreliability. One reason why after almost 30 years of buying a new JLR product every 2-3 years I didn’t replace my 2015 RRS with another Land Rover in 2018. Seems to me that they have become a company ruled by bean-counters and litigation avoidance experts now. Seems like they are scared stiff of honesty, “hey folks we messed up here, we are sorry and will cover all the costs to put your very expensive car right”. I wonder if a few more customers were to involve the leasing or finance companies that they use to buy the cars more when there are serious problems like design faults that those companies would refuse to finance JLR products.......... certainly a few years back I involved the finance company who provided my PCP when I had issues with a new Evoque JLR moved very very quickly to fix all my issues but when I read on RRSport, BabyRR and DiscoSport forums of the issues some people have it seems few people involve the company that has actually purchased the car that they are basically renting. Pangea Green D250 90 HSE with Air Suspension, Off-road Pack, Towing Pack, Black Contrast roof , rear recovery eyes, Front bash plate, Classic flaps all round, extended wheel arch kit and a few bits from PowerfulUK Expel Clear Gloss PPF to come

Some very interesting links there. Thumbs Up

I found one with some tech links here:

https://www.pistonheads.com/gassing/topic....;t=1833015

Most shocking is the fact JLR used SOTA update to change to service message appearing at 10% dilution despite "The possibility of mechanical failure highlighted by JLR will rise: we can predict 66% more engine failures due to 10% dilution." Shocked

considering the appalling reliability of the Ingenium engines, I am somewhat reluctant to fight SWAMBO on this...

Soo I read out of this that JLR are playing a very risky game of ostrich (head in sand) due to the design layout of the exhaust - DPF - SCR something that has blighted other car manufactures earlier on and lesson have not been learnt.

Peugeot with it's early HDI engines used to like blocking up DPF's so PSA used an Eloys fluid to catalyse the soot in the DPF to burn it off and help keep post injection down. The 1.6 HDI was famed for dilution in the oil and it would kill turbo's for a hobby. the dilution with small oilways / higher blowby / wrong oil's / drive cycle less than idea. Even then owners reported 10k oil changes were not enough to stop the sludge building up on some it is an engine to avoid.

VW again with the long distance again to the DPF means that regeneration is a long process as it's got a long way to heat up. I'm forever telling customers that 5 miles to town and back isn't a good thing to do, and they need to get onto the bigger A roads at least once a month and 'clean the cobwebs out' coupled with a bottle of Forte and a prayer.

Our 'old' defender is blessed with a close coupled DPF and that is something that I knew going into ownership was something that is proof against the naysayers who decried the 2.2 because of it having a DPF. The whole DPF's are bad are really only a thing as many manufacturers believe that they can use them remotely and have no issues with a stop start driving cycle. Something which I still don't think is tackled head on at the dealership on the sales desk.
"Yes sir you can put your order in but this engine around town is gonna require a very short service regime"
"I suggest the petrol as what you loose in MPG you gain in longer service routine"

I'd be interested to know how much knowhow is on the sales floor to give the customer the facts of life when it comes to city driving and using a engine not capable of performing as such. Now the question is will the new defender be like the Velar with a close coupled DPF or a remote one? Also can be found on Fb, Ytube, Insta & Twitter @4WDSouthwest

Some shocking information there, ultimately questioning the integrity of the type approval process for the D8 architecture.

Million dollar question: does the new Defender have a close coupled DPF?

Don’t forget that all new petrol engined vehicles delivered in the EU since July 2018 have also needed to have a petrol particulate filter - we don’t seem to hear of problems with them yet. Pangea Green D250 90 HSE with Air Suspension, Off-road Pack, Towing Pack, Black Contrast roof , rear recovery eyes, Front bash plate, Classic flaps all round, extended wheel arch kit and a few bits from PowerfulUK Expel Clear Gloss PPF to come

On the topic of pollution, has anyone heard or seen any information on how much c**p was spewed across the centre of London on New Year's Eve from the firework display?

From the TV coverage it looked like a massive cloud of smog developed downwind of the display, blocking out most of the view for all those on the other side of the river.

When you think how dense, acrid and sulphurous the smoke is from just a few garden fireworks, the estimated £3M show in London must have had a significant impact on the air quality and emissions.

I would love to know what the equivalent vehicle usage in the LEZ zone would be to match the pollution from the display!!

petrol engine exhausts run a lot hotter and can bun off particulate in the filter

"Approximately 0.029 tonnes of nitrogen oxide (NOx) were emitted by the official New Year's Eve fireworks display. This is roughly equivalent to 0.00006% of London's annual NOx emissions.

We have not been able to estimate the PM2.5 emissions from the fireworks. However, we anticipate that most of particles emitted would have been water soluble which, given the display takes places next to the Thames and weather conditions were relatively damp, would have reduced their impact on ambient pollution concentrations."

Thanks Supacat.
Not much in the way of NOx then. I bet the sulphur and soot particle count was horrendous though.

I was going to do the mileage equivalent at EU6 levels but ran out of time...

226,562.5 miles for diesel cars...

In the first 6 months they estimated they had reduced NOx by 31% or 200 tonnes.
