Hi all,

Looking at the new shape Octavia with the 1.8TSi engine. Getting a bit confused, but is this the same engine as the 1.8 TFSI by VAG?

Anyone had experience of these engines? Reliability-wise?

Currently I run a 1.9 TDi (110 bhp), decided my next car will be petrol instead, as I am getting wary of the newer diesels and the issues surrounding DPF, EGR, dual mass flywheels etc.. The other issue I have is that the turbo on my current car has variable-vane technology and it has just got 'gunged-up' for the 2nd time, despite me driving it through the rev range as the garage recommended after the first repair. I believe variable-vane technology is only used on the diesel turbos, and not this particular petrol turbo. Can anyone confirm this?

Thanks

Yes, more than likely, but you may find that the Audi version has variable valve timing though.

VAG use the terms TSI and TFSI interchangeably these days, rest assured there's only one 1.8

So then I suppose the next question is reliability - anything to watch out for on the 1.8 engine?

No idea sorry its not very popular as so many people just buy the 2.0 TDI by default, and its only been on the market for a couple of years or so meaning its a bit early for any faults to emerge.

OP you might find it useful visiting the Briskoda website and see what people say.

Now I've got a hankering for the Audi A4 with the 1.8 TFSI (160) engine. The main thing that put me off the Octavia is that there is no ESP as standard, unless you go for the Lauren & Klemint(sp?) model.

OP, having exactly the same thoughts myself. My turbo is giving me grief at the moment, going into LHM when the boost rises, resetting on switching off the ignition. The car has been great for the majority of the time, but as the miles have been racked up and the various faults startedd to occurred, the cost of fixing them has become a factor. I also do not like the numerous reports of the problems with the 2.0l tdi oil pump, I had enough issues with the fan problems on my current car, really knocked my respect for VW quality, ridiculous engineering, and such arrogance to suggest it wasn't a problem. Some of the petrol engined alternatives, (not just VW), seem to give nearly as good mpg, and although I wont get the same tdi ooomph, from some of the non turbo-ed petrol engines, I'm hoping there would be less to go wrong/replace. ( I have me Elise for thrills smile)

I believe the TFSI is the older engine. Certaintly in the Skoda range it has been superceded by the TSI units.

I have the 1.8TSi in my Scout and can say hand on heart that it is a superb powerplant.

Skoda are quoting 160bhp but it seems that some of the units are developing upto 180bhp.

It is very, very smooth almost like a 6. It also has a chain instead of a cambelt which should be a good thing.

One things for sure I would not go back to my Octavia 1.9TDi !

I have only ever owned petrol driven cars ,would never have a diesel (though i do have a caddy 1.9tdi for work) My car delivers 36-41 mph even with 80k.

I will rest my case your honour.

Ok, back on topic now... So we've determined the 1.8 TFSI and TSI are the same engine, just different badges. So what about the comment above about it being chain driven on the Scout? Looking on the web, it seems that the 1.8 TSFI Audi is belt driven rather than a chain?

Also, to the poster above on the turbo oomph, this is one of the resons I'm looking at the 1.8 TSFI, as this is turbo petrol but still claims around 40 mpg combined (I know this will be driving 'sensibly' rather than with lots of overtakes...)
