Petrol or Diesel Engine VW Tiguan - 140TDI 162TSI?

[spicyrambutan]

It depends, ....if I'm going to tow the caravan with 4 people through the hills and at 110km/h on highway, I rather have the TDI under the bonnet, it will drive better. I hate to even think what the fuel consumption would be under these circumstances with the TSI.
Or which would last longer?

Oh, and as far as the extra cost for the diesel engine? If you pay your car monthly, then you pay less for the fuel every months, which will offset the extra cost. Plus the TDI should retain value better than TSI. Both can be tuned to get more power and again the extra power should be less taxing on the TDI.

I'm not planning on towing a boat or caravan, and I will be doing more inner city stop/start and suburban driving than country / freeway driving.

I'm sorry, I only replied to comment that TSI drives better. Wanted to point out that not in all situations the TSI drives better.

But, not everyone gets an "Ok" fuel economy when driving petrol engined car in the city, whereas the TDI will return very good fuel economy under all driving conditions for any driver.

I wish you luck with your decision, I'm sure that you'll be happy with the either.

Was told by the dealership that it's best to drive atleast 20km on freeway weekly with TDI engine to clean the engine. If you manage to do that on a weekly basis then could have more maintenance issues? Seems like old traditional advice but still worth considering

I chose the 140TDI. I'm averaging 6.5l/100km on shorter trips around the Inner West of Sydney and 5.4l/100km on longer stretches down the M5 (I have to do a 100km round trip every couple of weeks). This is my first diesel engine and having had it since early December I'm really happy with it. I tend to fluctuate between "normal" and "sport" modes when around town and flick it over to "eco" on longer roads (I do notice the car's acceleration from a stand still is more lethargic in eco mode). Honestly, I hardly notice any hesitation when in the other modes - it drives really well and there's never any hesitation when over-taking.

Some rough calculations based on diesel and pulp prices as well as approximate distances per tank for my particular driving usage sees the diesel coming in between $1000-$1500 per year cheaper in fuel on 20,000km per year. I didn't include other costs such as adblue (diesel only expense) or servicing costs (diesel is cheaper). My intention is to hold onto the car for around 5 years so that works for me.

That figure is specific to me and will differ for others but, to me, that meant the $1500 difference between the 140TDI and the 162TSI was effectively nullified after the 12-18 months.

For those saying the 132TSI - you can't get that in a highline so it's entirely irrelevant, the only comparison available in our market is 140TDI vs 162TSI.

It's really hard to give advice on this kind of question because there's so many variables to individual driving circumstances and preferences which should have far more bearing on which engine to go with so take each opinion, mine included, with a grain of salt and test drive both and choose.

I don't think you'll be disappointed with either as it really is an awesome car - particularly with the R-Line option

Mine (140TDI) is still on first tank filled from dealership and my long term is 8.9
Even I rest the consumption still 8.7. I have a 10km patch on 100km/h every day on a 25 km journey each way. Definitely not happy with consupmtion.
Not sure why its so bad.

The only reason I bought TDI over TSI was consumption and here I am.

It's the first tank. I can't remember exactly how mine was with the first tank but I am not sure I'd be too bothered with the results from the first tank alone.

I've had mine for almost 4 months and 3600km.

Having said that, your driving style and traffic conditions definitely matter. I was just stuck in the parking lot that is the inner west Sydney traffic on a Saturday and the car is reporting my usage for this trip at 11.5! Yesterday I did a similar trip, without the traffic, and got 6.5

Just wait until the engine is properly bedded in - typically by 5,000km.

If you're still getting high consumption take it back to the dealer.

Running-in an engine if you live in and drive in Sydney or metro areas can sometimes take more than 15,000kms. I have a 130TDI and took it to QLD and back when it had 7,500kms, spent 2,500kms on highways. On return engine felt much better, more alive and was drinking less. Was getting around 6L average after the trip, now with 19,000 kms can easily bring consumption down to 5,5 litres. Best I ever managed on M5 was avg of 4,9 with light traffic. If you are unlucky and stop on every red-light, that will push consumption up. With a new car, long term takes a while to bring down. Be patient. Where do you fill up? Diesel fuels vary big in Oz. That can play a role too.

Use BP diesel only. I found that the BP diesel gives the best fuel economy and power. Also, within the first fuel tank, the car would spent a lot of time idling on the spot and moving from spot to spot at the dealership.

The is no BP refinery in SA it is only in WA, unless diesel is shipped from BP Kwinana (WA) I suspect you are buying rebranded diesel from Port Stanvac (SA) which is a Mobil refinery. I am in the industry heer in QLD and this happens all the time!

I use Caltex Vortex Diesel beccause BP says it is Bio diesel and thought we werent supposed to use bio in VW. I get pretty good figures so wont be changing

BP Bulwar here in Brisbane, buy their diesel direct from Caltex via a pipeline under the river. Some of it they blend with an additive to make Biodiesel.... Normal diesel is refined by Caltex and rebranded by BP

Hmm, I rest the counter to make sure that it starts averaging for my trips. Every other trip I have the consumption is 8+.

I am in Canberra and I know the dealership will try to convince me on driving style but my driving style is not that bad. I own another Honda Civic which has manufacturer consumption as 8.2 and I vary between 8.3-8.4 means my driving style is normal.

All I can say is the quality of the fuel could be issue but as I can see people have been getting good mileage whether its BP or Caltex. Since, the consumption difference is not small its significant and that is why I am concerned. Mine consumption touches 20 (on blue circle) when starts from stationary and then comes down.
Today I did 25-30 km run on 95-110 Km/h while returning from friends place and got 7.9 still not good.

Will the computer diagnostic at the dealership will pick this up ??

Just allow more time mate, see what the consumption will be on next fuel tank.

There is no Port Stanvac refinery anymore, closed down years ago...
