Acceleration Hesitation

[ziggyboy]

So let's just run E10 into everything and see how it goes then?

Can you provide examples on where the term "bullet proof" should be used so we're clear? How exactly is the 118TSI bullet proof?

I would think only when using a gun and only at the block

"The One" has a bit of a point - the 1.4 twincharge engine is much more reliable in overseas markets than it is here in Oz. I certainly wouldn't call it bullet proof, but it certainly has a better reputation overseas than it does locally. It appears the reason for this is the local tuning of the engine which means that the engine runs very lean to get better economy. Very lean = engine runs hot, detonates and then you end up with a hole in the piston (which has happened to countless 118TSI engines). The detonation is more than likely increased with the 7 speed DSG and it's desire to be in the highest gear possible at all times and labouring the engine.

It would seem that about the best thing you can do if you own a 118TSI is to get someone to tune it - not necessarily for a performance increase, but that way they can richen up the air:fuel ratio to a much safer level.

I don't disagree that there are less problems in colder climates (South East Asian 118TSI's are also problematic). However, the term "bullet proof" in my opinion should be used where the reliability of the said component far exceeds the norm. Even if this engine had less problems in colder climates, does it necessarily mean it far exceeds all other engines in those regions???? I have not seen any proof to suggest that this engine is far superior compared to all other engines in Europe.

Does vw run different tunes for each country's fuel?

Over here we only have access to RON 95 and the cavd runs without any issues in 25-36 deg c weather with fuel having a higher sulphur content than that found your 95 and 98 petrol.

My Jetta CAVD says 98 and in small brackets (95). Says I should only use 95 when 98 is unavailable.

However other Golf CAVD engines only require 95.

ouch... that sucks.

The earlier files from VW ran close to lambda 1 under full boost .93 or something that I posted in another forum. Basically it never went below a 14:1 AFR ............not a good idea on our Aussie fake 98 let alone 95.
I've logged another stock MY12 last week and it was pretty lean coming on boost but OK in the top end so they've definitely modified things quite a bit now. Still there must be quite a lot of cars still out there unfixed and on Friday I was cringing at the sound of one rattling past me with owner blissfully unaware of the thousands of marbles I could hear bouncing around under her bonnet

I get a feeling a lot of people simply ignore the fuel octane recommendation becausetightarseaussies.

I know my father always ran his 2.5RX on ULP despite the manual saying 95ron. My sister runs her 147tsi EOS on ULP because "I don't drive as fast as you do" (which is untrue - I just don't slow down much for corners).

So between trying to "save money"on fuel & VWs marginal tune these 1.4twinchargers don't have much hope

I did get this fixed awhile back. It ended up being a cracked plug & faulty coil pack. Dealer replaced them all under warranty.
