Aktualne najazdenych 100 km a od zaciatku ma studeny aj teply motor zvuk ako diesel

Nie je to moje prve auto, okrem inych som mal aj firemnu Fabiu 1.4 16V 55kW - VW motor a ten mal diesel zvuk za studena maximalne 15 sekund po nastartovani, kym natiahol olej, atd...
najzaujimavejsie z eng forums:
My mate with a Corsa C (1.4 twinport) had his timing chain go at 19K. Sounded like a diesel, loud ticking coming from the engine bay. Got it fixed under warranty, now runs sweet.
Pride mi divne, ze by pri novom motore boli v prdeli rozvody alebo zdvihatka ventilovRattling noise might be your tappets or timing chain, can be replaced under warranty

Samozrejme sa s tym chystam do servisu v ramci zaruky, no obavam sa, ze zo mna urobia idiota .
Pls help, viaceri tu mate tento motor, stretli ste sa s niecim podobnym?
