  The well-known Bachmuth-Mochizuki-Roman'kov Theorem \cite{BM,Romankov85}
states that every automorphism of the free metabelian group of rank $\geq 4$ is
tame. In 1992 Yu. Bahturin and S. Nabiyev \cite{BN} claimed that every
nontrivial inner automorphism of the free metabelian Lie algebra $M_n$ of any
rank $n\geq 2$ over a field of characteristic zero is wild. More examples of
wild automorphisms of $M_n$ of rank $n\geq 4$ were given in 2008 by Z. \"Ozcurt
and N. Ekici \cite{OE}. The main goal of this note is to show that both
articles contain uncorrectable errors and to draw the attention of specialists
to the fact that the question of tame and wild automorphisms for free
metabelian Lie algebras $M_n$ of rank $n\geq 4$ is still widely open.
