    Did they replace all the pistons ?? (sorry if you've already posted this somewhere)

    I finally got my own 118TSI back on 18 December, with all four pistons and injectors replaced. They also updated the DSG software to the latest release.

    I'm still running in the engine, but I've noticed some improvements. The fuel economy appears to be around 5-10% better on my freeway runs, even though I keep changing the revs in the range between 1500-4000. The gearbox is a lot smoother, though there is occasionally a bit of clutch judder.

    On the downside, the idle speed used to be rock steady at just over 700RPMonce the engine had warmed up, but after this service it was rather rough, varying constantly between 600-800RPM. However, after a recent freeway run, the idle stability improved significantly, leading me to hope that the problem was just a dirty spark plug in the cylinder which had the cracked piston. If this is the case, some more long drives with the engine fully warmed up might fix things.

    In any case, once the holidays are over, I'll be taking it to a specialist tuning mechanic to get it looked at. I'd love to be able to keep the car, because when it works, it's fantastic!

    yes they said they replaced all the pistons and injectors and a bunch of other associated bits and pieces. Waiting for a call from Essendon VW to advise what they find. Have to say Russell the sales manager is a star, no questions asked arranged a loan car from the lot for me again. Will keep you posted.

    Hi Sentinel I hope you have better luck than me. Sounds like we got our cars back around the same time with four pistons and injectors replaced and the service recalls and dsg updates etc. They thought mine was due to one of the rings self destructing or had been installed badly from factory. Who knows, sometimes I dont think we (owners) get the full story. Anyway mine was running nicely too with definately stronger accelleration until yesterday when it just stopped fingers crossed you dont have to any issues.

    Now I'm worried too. At least my car is still under warranty.

    I'm still going to get it checked out by a professional, as soon as the holidays are over.

    Ive just about finished my R & D with a mk5 GT 1.4 and I have to say all these failures do not suprise me . Piston to bore clearances all over the places , really crap cylinder head casting , intake air temps through the roof at idle and absolutely no cool airflow over the engine on a hot day its only a matter of time before the engines grenade . I'll put up a post shortly on what Ive found and what Ive done and hopefully it all works (VW just throw another engine in so dont expect them to magically fix the issue!) .

    37 degrees in Melbourne today and my intake temps were hovering around 57 C for the most part, dropping slightly when on the freeway (high speed with low load). Need to hurry up and get the S3 FMIC installed so I can measure the improvement.

    Quite a few people have said that Australian petrols fall short of their official octane rating. For instance, that the fuel sold as 98RON is really only 96RON.

    Would it be helpful to use octane enhancing additives? I've seen a few made by Nulon or Wynns, that promise to increase octane ratings by anything from 4 to 8 units.

    Are such additives safe for use in the 118TSI engine, or could they cause damage?

    I'm quite interested in this question, because predetonation destroyed my engine, and all pistons and injectors had to be replaced under warranty. I don't want that to happen again, but I'd like to know if there is any downside to using octane-boosting additives.

    Update, for anyone who's interested: I asked a similar question in the petrol and lubricants thread, and received a few useful answers.

    Octane-boosting petrol additives?

    I think I'll use the Wynn's additive in small quantities, until I can get the engine checked out.

    Still no news on my car. Not even a call to advise when they will know something. I had to chase them only to find out they have not even looked at my car yet grrrrrrr
