Weird noise when starting the engine

Hi,

I have a loud weird noise when starting my vehicle listed above, Enima (see beginning of video attached). Sounds like a cranking noise or wrong meshing noise and last for a second. Then the engine starts and run correctly (RPM okay and oil temperature rise okay). Does not seem to be linked to cold or warm engine. The solenoid contacts have been changed because signs of wear but the problem reoccurred the same day.

And bad luck, a second noise appeared, a while after engine start. Sounds like a wheel bearing noise but not sure (same video at one minute 05 seconds). You can feel the vibration under the foot when driving. The engine sounds fine. Once the sound has stop it does not happen again, until next start. I am not even sure the two are linked though.

If someone has an idea or encountered a similar issue, please help! :-)

Thanks in advance.
