    Yes, this is the problem and put quite simply in technical terms it is being run “lean”, too lean and it doesn’t work on all cars as they vary. If you are prepared to pay for it you could have it remapped where the feeling tables could be tweaked to increase fuelling in certain situations. A look at the lambda target tables would show an experienced custom remapped where the fuel was needed plus you would have to accept a small increase in fuel consumption.

    I got A3 8V 1.5 35tfsi 1.5L with stronic gearbox and experiencing "jerky" gearbox but after reading many posts about 1.5L evo engines "kangarooing" issue I started to think it might be the engine not gearbox. Most other posts mention manual gearbox. Does anyone know if same engine with stronic gearbox is affected? Thanks
