Factory diesel Jimnys (DDiS) - all info about them

I rest my case again Isuzu 1.7 is a great little engine not to heavy 90bhp without tweaking puts that French pile of shite to shame

Working in a non main dealer garage i see alot of different makes of cars.there isnt a week goes by that we dont have some modern diesel in broken,at present we have a 60 plate focus 1.6 derv thats looking like it needs at least 3 injectors.the 1.6 in this focus is a french unit used in pug shitroen ford volvo and mazda,we see alot of volvos with this engine as we are a volvo specialist.we had an s40 2 weeks ago that needed a new high pressure pump dealer part was a fortune.we have done just about everything related to this engine on different cars.

the renault 1.5 lump isnt a particular nice motor either,suffering from all the normal issues seen plenty with egr injector turbo excessive oil consumption.

Having owned many a "proper" diesel im partial to the isuzu 1.7td lump,fitted one out of a cavalier into my astra dti mk4 after the dti gave up at 140k.the isuzu lump had 200k+ on it,i did the white ring mod bleed valve had a straight through exhaust etc it went like stink and it got abused daily while running 50/50 svo derv mix.never missed a beat great little engines.

for me the problem is i see so many knackered car's /modern diesels it puts me off i wouldnt have a modern derv over a petrol any day.the best time to own a new diesel is when its new and you have the warranty on it once past 5 years old the issues rear there heads.

personally for me i wouldnt put the isuzu in my jimny as sitting at 55mph its at 3750rpm the isuzu would be nearly maxed out at 60.if i had loads of money and could trailer it to events i deffo would.buying a new jimny if i could the choice would be petrol over the derv anyday.

My 2p's worth

So it is a follows:

The 1.7TD Isuzu is better than the 1.5 DCi because:

It's Japanese
It runs 200.000-250.000 km's without using oil.
The 1.5 DCi is french
1.5 DCi is crap

Wow.. Those are some solid arguments..
What about the issue of not being able to find a suitable gearbox for the 1.7TD? Running it on petrol gearbox just suck. What about the 1.5 DCi being much easier to get more power from? Probably lighter too (don't know, just a guess)
Also, 250.000 km's isn't exactly a big deal on a modern well maintained diesel.

And claiming the 1.7td is better than the VW 1.9TDi, seriously?

One of the best diesels ever made is the Mercedes OM605/6 engine. The 1.7TD is not even close to this.

Thanks for your comment Gaz

Don't know how it is in the UK. But here in Denmark most new cars sold are diesels. People buy diesels without even looking at their needs. They let the mileage be the deciding factor, and that's it. And then they use it for commuting, 5-10 km's to work... never letting the engine get warm. With all the issues you mention to follow.

So I'd say, that most issues with new diesel is related to the owner. Not seeking the necessary info regarding how a modern diesel needs to be driven.
Yes, new diesel are more delicate than old diesel. But does that make the engines bad?
Not in my opinion. They run far smoother, quiter, just as many km's if not more, better mileage.

More than likely the same here but more of a mix of both, imo I think its going full circle and people are moving back to petrols.certainly ones who only do short journey's. Dpf issues for fun.

most of the cars I see they are down in the price bracket with a few miles on them with people reluctant to spend on maintenance and just doing whats needed to pass an mot or keep them on the road, (I live in the north east of england not a money area).you could get away with this on an old school diesel would run forever but not modern stuff.i appreciate they are a bit more refined but for me emissions laws has ruined what a diesel was all about.

my parter inherited a 2012 vw tiguan when she got a promotion at work she only had the car 6 month as it was due to go back to leasing company, she was averaging about 5000 miles a month, had a full vw history and the use it was getting was the right use for a diesel imo, it was on 127000 miles a month before it was due to go back she came home parked it up 2 days later we went to go out in it and it wouldnt start had to be recovered, turned out the fuel pump had went on it.it was always ran on premium fuel and never supermarket fuel as this was instructed from the lease company.by the end of the lease to me it felt very worn and tired and no doubt whoever hs bought it will start seeing issues with it.i will never be sold on the modern stuff at all.

First of all,about 250k kms on a modern diesel not being a big deal, sure, it's not. Getting there is fine. You just need to then take into account how much you spent on the shop taking care of sensitive cloged up injectors, shot fuel pumps, new egr, maybe a turbo rebuild an a new flywheel.But hey, guess the miles are all that matter.
Having had a ddis jimny i spent has much time on renault forums as i did in jimny and suzuki ones.
The amount of people with engine problems on dcis was absurd.And mostly serious and expensive ones. One may quote the millions of dcis around without problems, but i've never heard so many reports of problems from any other engine. And not just one chronic problem,but a whole host of them. Bad quality brass on the con rods leading to crank damage and broken blocks, desintegrating fuel pumps and wrecked injection systems, dual mass flywheels,shot egr and turbos. Not to mention the cases you never hear about.
And as for being easy to make extra power from a 1,5 dci, i sugest you do some research on that. Sure,it comes in every flavor from 65hp to 115 or 130hp, but the block is all they have in common . A 65hp dci has a maximum output of 90bhp,via adding the 85hp variant's intercooler and a ecu reprograming tho increase the boost from 1 to 1,1 or 1,2 bar. To go above this you would need the turbo from a 90bhp or 105bhp variant wich i think is a variable geometry unit, along with injectors,fuel pump and pistons from a 105bhp variant since the 65 o 85hp variant's would be damaged by the extra fuel pressure . This would most likely run you into the thousands. You can get a maximum of 20 or so hp from a dci engine before running into problems or spending a lot of money. Now, how much is it to sawp an engine or to turbo a petrol?
Ill say it again,the dci lump is an utter pos. You either treat it like a newborn baby or its gonna be trouble.
