Time for the 2.1 version of my Mercedes OM471 engine sound, plus a big bonus, i have rebuild the new SCS recordings of their DD15 engine sound (OM473).
So now you will get two differents sounds for the Actros.
My OM471 has been improved a little bit and i have also added the interior original accessories and the air brakes, with of course the ugly air gear sound of the Actros
They both sound very realistic. )
Of course this works only in 1.39+ version of the game.
