Sensitive observations reveal that radio-quiet Active Galactic Nuclei (AGN) are not radio silent. A strong correlation found between the nuclear 2-10 keV X-ray and radio luminosities for a well defined sample of local Seyfert galaxies, suggests that the accretion flow and the radio source are strongly coupled. In these sources the accretion rate is linked to the radio-loudness, as expected in low luminosiy AGN where an advection-dominated accretion flow is supposed to be coupled with a compact radio jet. However, the same correlation has been found also for high luminosity AGN where instead standard accretion thin disk is responsible for the high energy emission. We present recent results on VLBI radio observations of very low luminosity AGN which had revealed an ubiquitous presence of sub-parsec cores and/or structures going down to sub-mJy flux densities compatible with jet-base or outflow physical scenarios.
