Hi Everybody,

I want to order new yeti AWD this week but cannot decide between those two engines.

Never had diesel before plus DPF problems scares me. On the other hand

this TDI engine is more economical. I don't drive very long routes usually, mostly mix

between town and suburbs. How about cost of servicing, is it higher for diesel? like parts etc? 

Probably I will be doing some off-roading so does type of engine matter here?

thanks

What DPF problems :P

Id describe my 1.8TSi as bulletproof considering the non factory standard power levels its subjected too. And 44mpg on a 70mph cruise.

I had some misgivings about this DPF thing before the guys here reassured me that all would be well.  Our typical journeys range between 3 (ouch!) and 12 miles, with something rather longer perhaps once a month.  Then of course there are the holidays with real distances involved.  If I think recent mileage might have been a bit too short and cold overall , it's the perfect excuse to visit a nice bit of dual carriageway and carry out the prescribed remedial exercise 

As above, what DPF problems?

Now done 71k miles and hardly ever notice a regeneration.

 

Servicing on the diesels seems very cheap; first at 18k was less than £150, 36k was a bit more, 55k was more but included Haldex oil and brake fluid change. Has never exceeded £300. As a comparison, my Freelander at a local independent, would cost me around £160 each 12k, and I was too frightened to ask what a main dealer would cost!

Servicing at the moment is very cheap...free for the first three years/services

Unfortunately, with my annual mileage, it wouldn't have been applicable for me!

HI Zorro, and welcome to the Forum.

I have had 4 diesel vehicles since 1978, (so I'm a bit Biased),

Have have been Serious, 4 WD Vehicles,all have done between 250,000/320,000 KM, with no major problems.

All except my latest no problems, ("Snowman" TDI 2.0L 4wd, auto) which is so car like, yet except for extreme 4WD,

is as capable as any I've owned, it has 18,000 KM on the clock.

The only thing to remember is that you need to warm a diesel motor up before driveing off usually 3/4 minutes,

if that is not suitable, go for the petrol motor, but haveing a Turbo you should do the same as above in the mornings.

I'm a Aussie and on recent trip up the Beach at Noosa North shore,

there is a place called the cutting which is the only way to get between the beaches, it's cut by a Mountain Range.

Long story short a Patrol owner with a 4" lift kit, said your not going to take that toy through there,

I had the greatest pleasure in hooking my Snatch Stap to his rear bumber and pulling him out after he got bogged.

So my Yeti has proven its a serious 4WD,not an AWD, just have to be aware of my ground clearence.

Hope this has helped, and not confused you more.

The reputation of DPF issues comes down to when were fitted to the older PD engines.

As these engines were dirty compared to the current CR engines they had a lot more work to do, used to get blocked and have more failures.

 

The newer Common Rain diesel engines are cleaner burning and designed to work with a DPF, hence very few issues.

 

Out of the two engines, both are strong.  Both can have faults, just like the small minority of any good engine can.

 

If you want torque and economy go for the diesel.

If you want less noise and smoother progress, get the petrol.

DPF issues are a nightmare across all makes and models, so I find it hard to belive Fox's argument above.  This has even featured on BBC Watchdog.  There is also the Dual Mass flywheel.  With these in most cases it is a matter of when they go, not if.  Then the fuel injectors are also fragile.  Get the petrol and get it converted to LPG.

DPF issues just don't happen anywhere near as much now as they did Allen.

The PD engines had DPFs fitted to pass the Euro emission rules, but they weren't designed for them.

That's why they suffered more issues.

Ask a dealer, they'll tell you the same.  Mine did.

 

The petrol had issues too with the timing chain tensioner that lets go.

Just like B33fy's VRS did, wiping the engine out.

 

I'm not convinced there is a great difference in reliability between the two engines.

Utter tosh!

DPF:

There have a few stories on Witchdog, and none have been with the current range of VAG diesels, and most have been because owners haven't followed the advice of the manufacturers in the correct use of their vehicles.

DMF:

Likewise. Both my Freelanders had them and both did 100k with NO problems. My Yeti has done 71k with NO problems. Nearly all the problems that have been recorded have been due to poor driving standards.

LPG:

You must be joking?? Hardly anywhere sells it now, it takes up too much room in the boot, and it is nearly as expensive as petrol!

Do you have personal experience of these alleged problems? Do you not think that if there were  problems we would have heard of it on this Forum?

 

Fred 

In 32,000 miles I wouldn't have known that I have a DPF if it hadn't been for this forum

26,000 miles here and I've only twice heard the car regen as I switched it off and got out and not once in all those miles and nearly 3 years have I seen the DPF light come on.

 

As Bossfox explained most of the issues came about when PD engines and other older diesel engines had DPFs fitted to them BEFORE 2009 to meet the then new Euro 5 legislation.  The two were not really designed to work together and add to that silly drivers not reading their manuals and voila: DPF carnage.

 

On a Common Rail engine that has been designed from the outset to have a DPF you will have little problem if indeed any at all, as most people can attest on this forum.  And in saying that is there even ONE thread in the Yeti forum where someone had catastrophic DPF issues?  Yes TP's regened a bit more than it should but I can't think of a single thread about anyone with a catastrophic DPF failure.

 

So the choice between 1,8 and 2,0 TDI is more about MPG I'd say.  Work out the fuel cost over your expected mileage in the time you will own the car and you will see which to go for.

Zorro says 'I don't drive very long routes usually, mostly mix between town and suburbs.' I would say that over shorter journeys, it's difficult to tell whether diesel or petrol has the better economy. Diesel takes quite a bit longer to get properly warm (15 miles plus?) and it's not going to deliver optimum mpg until that point.

I'd suggest that if we were talking about journeys of 30-50 miles or more then the diesel is undoubtedly the more economical. Over shorter journeys, and especially eg a 5-10 mile commute, possibly little to choose on the economy front.

From experience of cold (-6!) early morning starts you start to get heat out of the vents after about 4 miles, and the temp gauge is at normal after 12 miles. Oil temp is a little slower.

IME Oil temp is quite significantly slower and oil temp seems to be quite a good surrogate of mpg, eyeballing the maxidot figures.

thanks  Gombax, I have no doubts of yeti 4x4 capabilities because I have read about haldex a lot plus many very good cars use that system.

You're mostly talking about older engines which indeed had great reputation, cureent diesels are not the same, aren't they?

I mean 18k miles or 30k miles is still not ennogh I think to be sure.  I read some parts of new tdi engines like flywheel can break around  75k miles.

1.6TDI more often though.

 Obviously speaking from experience there...   :wonder:

 

 I have had four cars with DMF, all did well over 100k in three years and never had an issue with DMF, usually they let go when they have been abused by poor driving styles, riding the clutch on a hill instead of using the handbrake and such things.

 

 DPF, fitted on my Audi and one on my Yeti, no issues other than a sensor on the Audi that was replaced, 143K on the Audi when it went, now I have the Yeti and it has 93k on the clock after two years, DPF issue, no nor a DMF issue and I have to add my cars are always on long life servicing and get well used.

 

 So, I suggest to the OP that your comments are ignored as they are misleading to say the least. 

I've had both and did have some issues with the DPF -none that impeded use of the car but some which necessitated an unplanned journey to get the light to go out. No attention needed from the dealer and no limp home episodes. In my case I am happy to admit it was a wrong choice of engine by me-I loved the effortless progress and the long range-on a long trip the car was peerless. My daily commute however was entirely unsuitable (1.9 town miles) and my weekend trips diminished for family reasons. I have a petrol now and am very happy with it but am more than 10mpg worse although on cheaper petrol and under 10k a year I expect I won't end up worse off by any significant amount.

zorro onenote troll funny not random words

Well done to Yeti-Man for getting 44mpg on a 70mph run.

 

Realistically Zorro, for your type of journeys you won't see that kind of mileage out of a 1.8 petrol.

I think I'm right in saying the 1.8 petrol is the worst in the Yeti range for economy. I didn't want a Diesel but wanted a petrol engine, with some umph.

I also do short journeys too and from work (3 miles) which is killing my average mileage from new, which is at just under 27mpg***.

On a 25mile run out to the hills of Derbyshire on 30-50mph zones I'll get an average of 34-36 mpg***.

I don't drive in a way to try and use less fuel, I like to put my foot down when I can.

 

Some on here comment on the 1.8 being fast. I wouldn't say it was fast but it is definitely no slouch. It is quite a torquey engine though and it will stay in 6th gear on motorway runs, even up a modest incline.

That sums up the standard 1.8 well IMO. My daily commute is 10 miles each way and I usually see 32-34mpg. The petrol warms up far quicker in winter and doesn't suffer the dramatic difference in lower mpg as the Tdi does as a result. Also, the petrol doesn't 'feel' as quick but it is actually quicker than a 170 when you use the revs fully.
