Today I was driving my car and everything seemed normal as could be. However, after some time I noticed a strange sound coming from the drivers side in the engine compartment. These kind of sounds are never easy to explain, but the best I can think of would be a whooshing sound with a metallic note. At first I thought it was the wheel or something maybe stuck up in the brake or something. It goes away when I let off the gas/depress the clutch. Then I thought no wait a minute, must be connected to the driveline because of those characteristics. Well, I am certain it is the turbo. Took my dad fr a spin and he agrees. Anyone had a similar occurance or any other opinions? Could my turbo be failing? Dealer visit this thursday.
