Idle or Power Problem?

[andy64]

Got similar problem after 5k km. Vibration at idle (app 600rpm). Very annoying- particular waiting under traffic light and support head at vibrating headrest. Plus back massage in chair.
Reported at service several time. First time they clean Tbody. Worse -vibration switched from H frequency to low. Then Toyota service tell me" that is a normal" .
Sorry. I am not paranoid. Similar to last service when my brake pedal starts to sink to floor. Service officer also tell mi is a normal.
After bleed the system - problem vanish.
Frankly, I do not know as vibration is normal or not . I never got similar in past in any car. Better petrol (98) gives slim improvement -but not resolves problem. I am very angry but powerless. Regret my decision to buy Yaris

As i was checking cables related to TB i found a buildup of oil near the alternator and timing belt, i have read some post here from a user Hershey telling about a common problem yaris 2010 with the head gasket, is this true? If it is, can this somehow affects compression in a way that the vibration i'm experiencing is caused by this? I'm thinking of buying a UV oil kit to see if the buildup is caused by changing the oil or an actual leak
