The sivide that was from mine was from siren ambulance and in the house I was repaired by the Turbo 1200 euros, the tulla did not forums to ask a mechanical that sounds in Congrete makes you.
Also make sure there is no manquito of admission out of the turbo punctured, because if he escapes some air, even if it is a pore, it is a long whistle, and not notes lost power. Review the pressure manquitos with the engine a bit accelerated to see if you notice a jet of air to pressure, the same can happen with the intercooler. Greetings!!
