    Loud buzzing noise starts 15 seconds after cold start as oil pressure increases. Seems to gradually fade as engine warms up.

    appears loudest at the two braised oil hoses on drivers side.

    what is causing this buzzing noise? Doesn’t not seem to be the oil type.

    Maybe one of the two hoses is sitting against the inner wheel arch which amplifies the noise?

    Sounds like the oil pressure relief valve is lifting, but you normally cannot hear it, might be an idea to have a look at it.

    What sound when accelerating engine ? Does it stay the same or its gets louder ? I'm thinking it can be the intermediate gear bearings.

    The oil relief valve will lift when cold, the fact it stops when the engine warms up makes sense as the oil is getting warmer
