Hi fellow owners,
I would just like to pass on a good and unexpected outcome regarding a worsening turbo howl/ moan that developed with my 2014 prado VX.
The local Toyota dealer had replaced the original turbo under warranty with a new hand- balanced one but with no real difference experienced with the moaning under load. I was thinking I might have to put up with this noise long term but later a problem developed with a rattle from the exhaust at about 800 revs and to cut a long story short, the rear muffler section was replaced under warranty because it was found the baffles had broken down and subsequently a miracle happened- the turbo howl reduced by at least 50% ! Maybe something to do with exhaust gas harmonics? Anyway, hope this info can help someone.
