In galaxies hosting AGN, gas outflows likely play an important role in regulating the star formation hence the galaxy evolution. Recent studies point to a close connection between these outflows and the detection of compact radio emission. The observed non-thermal radio emission could be associated with radiation-driven winds launched by the disk or with jets and lobes of weak and small-scale radio sources. Discriminating between the two scenarios is important to understand how feedback between the AGN and its galaxy works. VLBI observations probe the radio emission at high-angular resolution distinguishing core and jet-like features from diffuse emission. However, only a small number of sources has been observed so far. The nearby galaxy MaNGA 1-166919 is an ideal target as a bi-conical outflow of ionised gas co-spatial with a double-lobed radio structure has been discovered. No clear jet-like feature is visible at arcsec resolution. We propose EVN+e-MERLIN observations at 1.7 GHz in order to investigate the radio emission with unprecedented sensitivity down to millliarcsecond (a few pc) scales.
