EXTRA NOISE

[ste-vx2]

I hear a funny noise when I accelerate that is NOT coming from the engine because it's not revving up or down nor from the road. The noise only occur when I press the acceleration harder at any speeds and it stays the same regardless what speed or rev I have. Has anyone experience anything similar? What to do?

If you look in the rear view mirror when the funny noise occurs you will also see some flashing blue lights.
Probably best at this point to stop the car before you do any further damage.
But seriously, just take the Adele CD out of the head unit. Problem solved.

ah yes the infamous "noise"

dude, try and be more descriptive please.

Yep, so it's like a humming kind of a noise that once is there stays there for as long as the hard acceleration is on, permanently, something like: "hushhhhhhhhhh" and it activates when I press the acceleration more. Not a rattle, not ticking noise, nothing super loud. If I accelerate lightly there's no such noise whatsover at all. So I accelerate lightly up until 30km/h then press harder. The noise activates as soon as I press harder. If I become light on right foot, the noise goes away as nothing ever happen. I accelerate lightly up until 60km/h then harder. Same, noise activates then. I accelerate harder from the traffic lights? Noise kicks in straight away.

that certainly is a description, got me beat can't think of any humming noises. Do you feel anything (other than dread) when the noise happens, like is it a vibration?

only thing i can thing is that perhaps at those k's the engine mounts or something are worn and you are getting a vibration.

 

[ste-vx2]

No, no vibrations. The engine does have a small, very small trepidation, when idling, but that's just the engine. I'm suspecting the transmission...

Transmission slipping?

Wheel bearing most likely
