Turbo/Engine Noise

Turbotim · Mar 9, 2011

Hi I have a 2010 ST D40 that has just had its 20k service.
While it was there I asked my dealer about what I can best describe as a Turbo Flutter noise. It happens when you rev the engine above 3500 rpm & change to the next gear. I thought it could also be something loose which is vibrating. The noise appeared just before the 10 k service & I asked the dealer about it then. They changed & bled the clutch fluid. This time they said it was normal & was the waist gate.
Has anyone experienced anything like this?

There is an issue with the turbo actuator in the 2010 ST model. Nissan know about it, and replace the unit. You'll eventually experience surging and failure to boost without check engine lights or error codes being generated.

That second thread has a link to a video on Youtube where you can listen to the sound made.

Car went for 30k service & I asked about vibration again.
This time they told me that they had a problem with the clutch line
& needed to order in some parts.

A couple of weeks latter they rang me to let me know part were in & I sent it in. Result all fixed Vibration gone.
