So, what are the benefits of the TSI FL Octy II against the pre FL TFSI?

I already know its quieter (not sure if that's a benefit), rides a little better, and the trim is nicer with some nicer features.

I had a short test drive, but not enough to know what it's really like. How does fuel economy compare between the two (in standard tune).

It also seems from some threads that it responds better to a generic remap than the TFSI does. What about oil consumption - any worse?

I've searched the site for as much, but I'd need a week to find / read all of the FL TSI posts, and I have to make a decision tomorrow morning.

Better fuel economy, emissions and is chain driven. Expect better reliability too. Is basically a detuned version of the MK6 Golf/Scirocco engine.

I understand it remaps slightly better than the TFSi.

One known issue with the newer engine is catastrophic engine failure due to cam chain tensioner failures but they arent that common.

All in all the TSi is a big improvement, just doesnt offer any real performance advantages as standard.

what about the rest of the car?

I don't think there's a *lot of difference between the rest of the pre and post facelift cars, they will still share many of the same parts, although some will obviously have been revised.

I read an Evo or Auto Express test on the Edition 35 that suggested the EA113 (TFSI) engine was actually a bit stronger than the EA888 (TSI). I daresay they both have their strengths and weaknesses.

So far, the TFSI engine is largely bomb proof. The harder I drive mine, the less it's consuming oil, and runs sooo smoothly.

The Tsi isn't detuned from the Golf engine they just don't tell you that it's the same !

@bullit, the engine is identical as is the ECU

However , the difference between the two cars is the GTI runs marginally more boost hence the marginal increase in power.

My 2.0 TSI was 215hp stock.

What timing chain failures?

FL car is nicer, more up to date with some of the modern VAG technology. Personally think its better looking too.

If you can afford a FL id say get one over a pre FL.

And yes the EA888 engine in the Octy is the same as the Golfs but it is it wound down to 200ps, has a different engine code too.

Go for it. Great car. The radiio, clocks are different, more modern, there is no cambelt to change. Performance wise, there is no startling difference and fuel economy is (according to the figures) not much different. My TFSI normal avg is 35-36 Mpg. It is lower in the winter and higher in thrasher weather. I prefer the preFL looks and I am sure that the FL owners prefer their own cars styling. Otherwise they're the same.

one of a few threads on google.

Happened to me in my Leon FR. Chain tensioner failed and destroyed the engine. It happened on the Thursday in Aberdeen and Seat had a new engine delivered from Germany and fitted under warranty by the next Wed. Great service. Engine had only 6k on the clock at time of failure.

Seems like vag "knows" this us a field issue, and are probably keen to keep it under control before it becomes a full recall. In which case, it should be a straightforward process to get the repair done under warranty from now on.

Really. Where did you hear that?

TFSI seems to be more reliable for the moment. But since all TFSIs are a few years old it's not a straightforward comparison.

There are enough reports of TSI problems that I would be wary of buying for the moment.

Concidering this engine is in VERY wide use accross the VAG group I don't think there is an issue. Not sure on the number of engines they produce but it would be a very high number even if they have a 1000 it will still be a small number manageable over the Audi, VW, Seat, Skoda network over the multiple countries the sell in. I would not worry to much. That said if your not in warranty then this is a real heart breaker as your engine is toast. The pistons smash the valves to bits. The photos of mine were epic!

I'm prepared to take the risk, on the basis that it's a) very low, and since there are several precedents where it has happened and been replaced FOC under warranty, and c) I've got about 2.5 years of warranty left to run. At some point, if the problem is severe enough there will be either a service campaign, or worse a recall. The coil packs on the TFSI are a good example of a field service action.

Really. Where did you hear that?

Engine code for the Octavia is different to the unit fitted to the MK6 GTi and Scirocco, mechanically the same just with different mapping.

The rolling road your car was run on was probably giving generous figures, the 197hp (200ps) tuned unit would not be making 215hp standard I'm sure of it.

I remember looking at some logs from someone on here. Can't remember who though

What' about point B!! ;-)

Never heard JKM's dyno described as generous before.

Why would they even bother to change the map for a known product between companies.

That as the case may be and you may well have been lucky with yours running more stock power but its fact that the TSi in the Octavia has a different engine code and should be running less stock power. Its been discussed on here before somewhere.

I'm all ears.
