I understand that power, torque and consumption values from brochures are tested for N95 petrol. So this engine is really mapped (designed) for N95? Or, that " min.N95(RON/ROZ)" on fuel door, is only for commercial reason?

@korni
You are the first that I know who have this noise, with 1.8 TSI engine. Maybe is another source of noise. Also, nobody with 1.2 TSI complain about this noise.

This noise is specific (variable oil pump) 1.4 TSI engine.

Hello,
I am curios to know if you use only N95 petrol, or some of you use N98 and notice some improvement. Sorry I can not speak your language, I hope you will forgive me. I use for my 1.4 TSI 103 kilowatts from yesterday Mol EVO N99 and the engine sounds better.

So we have to live with the noise. Have a nice day.

@Rizan,
I see that the car came from the factory with 1/2 of normal oil quantity.

Hi,
It seems that the noise is normal for engines 1.4, 1.8 TSI . The noise is made by high pressure fuel pump , injectors and injector ramp . At cold start , in that split second, more fuel is pumped for start up because the engine is cold (you can see on RPM indicator, it rises at 1200 rpm as the noise lasts). Attach a video , at the end, injector noise is heard like the noise:

So that is the reason the noise is heard. The engine is cold, the noise will be heard. The starter has nothing to do with it.

Velmi dobře. V případě, že nejde o nic vážného, a já vím, co to je, a já řekl tiše. Nemyslím si, že je obtížné zaslat odpověď e-mailem.

Studovali jsme VAG fóra z Anglie, Francie, Itálie a Německa, a našel mnoho automobilů, které mají tento šum (motor 1,4 TSI 103 kW) .Nimeni nebyl nalezen řešení. Poslal jsem e-mail (s videem)) Škodových závodech a já jsem dostal pouze vyhýbavou odpověď. Myslím, že dál hledat řešení, nemá smysl.Automobilka a továrna, takže se nemusíte odpovědět na otázku. Je mi líto, že jsem si koupil tohle auto, lepší hůl na Škoda Octavia Tour 1,6 MPI 1/2008. Zdraví všechny.
