I know that the 1.6HDI used in pugs and Citroens is now not good. I want a diesel engined car but am struggling to know which ones are shite and which ones have sound engines.

Looking at 2006 or newer cars

Vag group PD130

1. Go to a garage at the weekend
2. Look for a car you like the look of
3. Test drive the car
4. If you like the car, buy the car.

If you are worried about used, buy a new one and let the warranty take care of any engine probs.

I think the budget for a 2006 might be a little less than a new car.

Appreciated. However, if it’s reliability and peace of mind the esteemed OP is looking for then perhaps a lease option would make sense.
To be fair this may have been covered in other threads so ignore me.

I think I mentioned in your other thread – the Toyota 2.0L D4D is a pretty reliable, cheap to maintain engine

Peugeot Diesel engines are still one of the best to buy

There all pretty much the same, and anyone who says different is just a fan of the one they like.

Different things go wrong in different engines all cost about the same to replace. the VAG ones last a little longer but you pay the premium when they go wrong. So it doesn’t work out much different.

Just service them and change oil regularly and don’t be to harsh on the turbo till its warm. and let it cool down no matter what anyone says.

VAG deisel engines are rubbish. Head gaskets go on them more often than people let on.

I unfortunately own a 1.9 CDTI (vauxhall, also found in Saab, Fiat and others i think) which i can confirm is completely sh1t.

I’ve given up trying to find a good 2nd hand diesel for 4-5k ish. If they work I think people keep them, its mostly the duds that are for sale. I think i’ll either buy petrol or spend more and buy at 1-2 years old and sell when stuff starts to go wrong out of warranty.

I didn’t have much luck with a VAG 1.9 TDI PD 115 engine either, mainly due to the head gasket going (seems i’m not alone in this happening), but by comparison with the vauxhall 600 quid to get it fixed with cambelt would have been a bargain.

Had several VAGS now and all been great or am I not letting on. MUHHAHAHAHA!

Had lots of Pug ones and all were great until the HDi came out, utter trash.

My pug diesel has never ever developed a fault and is some way from being regularly serviced

Owning a car is a leap of faith and you either get lucky or unlucky

We have no magic advice for you

Oh and to save time I like red coloured cars but the colour is never a deal breaker for me as a general rule 😉

ford tdci engine in my mondeo has done 150,000 miles with nothing apart from irregular servicing.
i always let it warm up before booting it, and always drive the last mile to the house gently.
and i regularly take the long way home to make sure it actually gets hot.
the main engine block comes from peugeot, and apart from various fords, can also be found in the x type jag as well.
(i am talking about the 2.0 unit here)

haratiohufnagel, where did you get that quote from my astra 1.9cdti, just had its head done, glow plugs, and cambelt and water pump by VX for £420,the cam and water Pump were due to regular service interval and the rest were down to begin on there first ones and sitting a 140,000 miles.

As you say if you have a good one you tend to keep them.

The quote was for the VW, not the Astra.

400 quid for all that work sounds very good though – where did you get it done?

said it before , maintainance and mechanical sympathy are key

if you rag it from cold , dont service it etc etc it will give up on you in the end.

now your buying a used car its a gamble as to what the previous owner did.

How many miles do you do ? from your last post i saw your motor was on 45k – it doesnt strike me that your benifiting from a diesel – stop concentrating on the “mpg figure” and look at over all purchase and running costs. youll probably get more reliability from a reasonable displacement petrol engine – which will be cheaper to buy and maintain , higher on tax and will have reasonable costs once you factor in that at the moment petrols about 6p a litre cheaper.

If this helps… the VAG group 1.9 TDI 130 in my car has now done 157k. It’s still on the original clutch, has only ever needed a preventative cam belt and water pump replacement at 130k. According to the full Audi service history, it’s only ever had four oil changes !!! 😯 ( Was on the long life servicing scheme, now switched to every 10k.)

trail rat has it.
my mondeo does more mpg than my wifes 1.6 petrol focus, about 50mpg vs 33mpg for the focus.
however the mondeo cost me £6k when i bought it, the focus cost <£1k.
5 grand is a lot of extra cash to save 25-30% fuel.
thats an extreme example, but the point is do your own sums, make sure diesel is the way to go for you.
when i bought my mondeo i was doing lots of miles (25k miles a year)
so diesel was definately the way to go, but when i replace it i will probly go for petrol as i only do 3-4k miles a year now.

+1

With diesels, I think there’s a certain merit to buying higher mileage cars.

Seems that if things are going to go wrong they do so early on, after 100k miles or so they seem reasonably indestructible bar normal wear and tear. I’m impressed that LenHankie’s 1.9 TDI 130 is on the original clutch.

Oh, and I’m pretty happy with my 1.9 TDI 130 – even if I did need to replace the clutch about a month after I’d bought it :/

I owned a vectra sri with the cdti 150bhp engine and apart from an egr valve when i first bought it I had nothing go wrong in 30k miles.

Bearing in mind it got ragged everywhere but was serviced regularly.

still did nearly 700 miles to a tank.

Now got a 2.2 mazda 6 and the engine on this is good to.

Clocked up 180k in my VAG 1.9TDi (130 PD) – never skipped a beat.

Original clutch, cambelt changed at correct mileage, and serviced every 10k.

Sadly got written off 🙁

It’s all well and good mentioning warranties providing the warranty covers those elements.

Personally think the focus diesel (1.8), Mondeo and Octavia engines are fine. Couldn’t agree more with trail rat. I looked after my 306 and it lasted really well. The 206 is awful but I don’t pay as much attention to it

Seems that if things are going to go wrong they do so early on, after 100k miles or so they seem reasonably indestructible bar normal wear and tear.

Well, I’ve had one of the old tractor engined Escort TDIs blow its head gasket at 128k
I’ve had one of the 2.0L TDCi engined Mondeos spit its turbo out in bits at 130K
It then started chomping injectors at 132K
I’ve had a 2.0L HDi engined 306 go without a peep from 60K to 90K before being written off being rear ended on the motorway.
I currently own a 2.2L TD4 engined Freelander 2 which has done 32K kms, with no issues.

So IME, the ones over 100K cost lots, the ones under did/do not – perhaps not a big surprise

I had an old pug 1.9 blow a head gasket. Current ford 1.8tdci doing perfectly well at +70k (nothing in the grand scheme i know). EGR issues can sometimes be sorted with a blanking plate off of ebay for a few quid.

I’d check the Honest John site for known faults. Turbo issues can be helped by idling for a few minutes before turning your engine off.

All VAG diesels – i.e. those in Volkswagen, Audi, Skoda, Seat and some Volvos.

PAS (Peugeot-Citroen) used to be great before they started swapping technology with Ford.

Out of the Japs, Isuzu are probably your best bet (Fiat and Vauxhall use them).

Out of the Japs, Isuzu are probably your best bet (Fiat and Vauxhall use them).

Only the 2.2 I think which is the Isuzu truck engine with a cam-chain. the rest are fiat designs (not a bad thing, Fiat invented the modern diesel engine design).

As for everything else, it’s pot luck 2nd hand. You could buy an imaculate one lady owner diesel with FSH and a reputation for reliability, then find the old dear had filled it with petrol 2 weeks earlier.

Get the car you want, that way at least you wont begrudge spending money on it.

Been looking to change my Mondeo TDCi with something a bit newer.Need a diesel as i tow a caravan.

Virtually every make i’ve looked at seems to have some inherent problem with their diesel engine.
The best seems to be the Toyota 2.0 D4D and the newer Mondeo with the 1.8 TDCI engine.
Due to emission laws nobody seems to produce a low tech diesel anymore,no egr,dmf,dpf,turbo etc.

“2.2 I think which is the Isuzu truck engine with a cam-chain. “

which is why ive ended up with a frontera

By the end of next week my 1.9 pd130 will tick over 205k miles…

Original clutch, exhaust, turbo, dmf etc. Cambelt changed every 60k miles, not ragged until warm, mainly fast A road journeys.70mph=1750rpm so it’s not really stressed.

I’d happily have another.

Nissan Primeria 97 diesel. Even from new the engine had very little power and is a belt cam but in 190,000 miles the only thing to wrong with the engine is the crankshaft sensor – £80 for the part – fitted myself in a hour. Original clutch too. Like the pugs, old school engines go and go.

Ford TDCI has the DMF issue though doesn’t it?

Ford TDCI has the DMF issue though doesn’t it?

They pretty much all (all modern Diesels ) have this problem

its not an issue if your not a serial clutch dropper.

if you have no clutch control and give it lots of shock loading then it can break up , if you drive smoothely and treat it well (there is a theme here) then it will last a good innings.

They are not an inherantly bad design , they protect other componants in the power train and smooth out the transition. If you didnt have a DMF you would have an insanely heavy clutch – anyone thats driven a landy with an HD clutch kit fitted knows what i mean. SNATCHY

buying used and cant change your own clutch then its just another reason to buy petrol or buy automatic !

Been looking to change my Mondeo TDCi with something a bit newer.Need a diesel as i tow a caravan.

Eh? WTF has towing got to do with needing a diesel?

might need the nose weight of the heavier cast block to avoid having to get a 3.0l + petrol.

said it before , maintainance and mechanical sympathy are key

if you rag it from cold , dont service it etc etc it will give up on you in the end.

now your buying a used car its a gamble as to what the previous owner did.

Bang on. The thing is if the OP is buying a car less than brand new then he has zero clue how its been treated before him and how it will let go due to the previous owners does he.

He wants to walk out of a known car into completely the unknown.

VW TDI PD’s diesels and HG- well known for the alu? porous heads aren’t they?

b r are you serious.
Diesels tow better than petrols unless you’re prepared to pay the costs of running a big V8 or V12 petrol.
More torque is produced and at lower revs.Look at the Caravan Clubs towcar of the year and see how many petrols there is.

307K on my 1.9 PD VAG . Original Head GAsket , and 1 clutch change .
60+ mpg in summer , 55 odd in winter .

I guess its all about the service history and how the previous keeper ( s) drove the car.

DMF and DPF are the biggest issues , injectors and turbos next , swirl flap and EGR on Fiat / Vauxhall/ Saab/ Alfa 1.9’s
Turbos on 2000 – 2004 Primeras used to fail
Mg Zt cdti fuel pumps go , and MAFs , If your 2006 or newer not an issue.
