Hello

if the engine has swallowed water by being driven through deep puddle or similar then yes its quite possible that its been damaged
sometimes in these cases its possible to repair the engine but often the bent rod or rods will end up wrecking the rest

so I'd suggest the most economic repair is to source a good used engine and have that swapped in

typcially expect to pay about £2000 for a engine and its aleast a days ( 8 hours) labour to exchange the units over

if a mercedes dealership was to tackle this then you're looking at a £200 / hour labour rate
So I'd suggest o use a independent as their labour rate will be about £80/ hour

as for locating an engine try the merc specialists

and if the work is done well then there's no reason why the car should not be perfect after this
