When did diesel cars get complicated?

I keep hearing how modern diesels can lead to problems. And only get one if you're doing over £12,000 miles a year. So wondered when they weren't so bad?

It's all about the exhaust emissions. No specific year, different manufacturers had different systems and dates.

Google euro 4, 5. 6 etc
 
have a look at the emission standards

Euro 5 was the beginning of the nonsense in 2009

the other downfall of the diesel is the aim for super efficiencies - one of which is spraying the diesel into the cyclinder at fantastical pressures, the stupidly expensive injectors capable of this don't last long - gone are the days of the million mile diesels
 
Diesels became complicated when people discovered the particulate emissions were harmful.
Like them or loathe them, you have to admit the clean up methods employed have been dramatically effective, admittedly with some complications.
Ever driven behind a classic petrol car lately? The pong is unbelievable and we all did it!

Neck sticking out......
Many cars of Japanese origin seem to be free of fuel additive chemicals such as Adblue, Eolys or whatever.....I've been told it's due to the position of the cat and DPF's but I can't qualify that.
'Er indoors has a 19 plate 1.6 Honda HRV - euro 6 and no additives that I'm aware of.

Anything in the last 15+ years will inevitably have a DPF, and probably Adblue as well.
However DPFs are not new, some older vehicles had them.

Even without, using a diesel vehicle for short journeys is a terrible idea.

As for used diesel cars you have two choices:
A low mileage piece which will be relatively new and therefore have been used on short journeys and be entirely ruined
or a high mileage piece which due to the high mileage will be entirely ruined regardless of age.

If you want some clunker which will last for ever, you are looking for something from the 1990s or earlier, and then the engine will probably run for a million miles.
However vehicles that old will very likely have bodywork that is entirely rusted and rotted away.

I doubt anything from 2000 onwards is going to be great on that score

the introduction of DPFs and engine management systems has led to diesels not liking short journeys

If you do too many short journeys the engine management will put it in safe mode.

Diesels have 2 expensive items: dual mass flywheel and diesel particulate filter and I guess the turbos are dear too
 
I've just bought a 21 reg diesel. It does have the pig's **** additive but otherwise it's great. I had a new, 22 reg, petrol car before that with one of those 3 cylinder crappy 900cc with a turbo rubbish engines and it was dire. Got rid before the clutch and the timing belt went south and bought one of the last largish diesel engined cars made with a chain timing belt. If I ever get another car, unlikely, it will be a self charging hybrid. They are crap but vastly superior to a full EV or the cars with noddy engines.
 
I have a euro 6 diesel with no additives and a DPF. I have never had the DPF light come on, I do loads of short journeys in & out of town and around the lanes, rarely I might go to a big town 20 miles away. Consistent 60mpg, whats not to like about that??

I must say having owned older mechanical fuel pumped diesels I was horrified at the complexity and swore never to touch it BUT I have not had too in 6 years of happy driving.

Not exactly. My 2004 Scudo van has the fantastic 2.0 HDi engine that was fitted to Fiats (JTD), Citroen, Peugeot, etc, etc. My model of van was manufactured up to 2006, so you can get a 21st century diesel with only an EGR and cat fitted. These two items are very reliable and I have only replaced the cat once in 17 years of ownership. No DPFs, adblue, etc - so handles short or long journeys without problems. At 108, 000 miles - for these engines, it's only just run in.

I hired a Clio last year with some engine like that. OK on the flat/motorways - but terrible on hills and inclines. Constantly having to take run ups and swapping cogs or it would die.

Having to always be thrashing an undersize engine must hammer fuel efficiency and engine life. Give me a big, lazy lump with power to spare any day. Preferably a V. :cool:
