Uh oh, DSG sound problem\question?
I'm a newbie with a 3.2 DSG & I've got a question. I'm hearing a fluttering/ticking/sucking sound from the engine compartment on the passenger side when I accelerate hard:
1. If revving the engine in neutral, the sound is not heard.
2. While maintaining a constant rpm, high or low, the sound is not heard.
3. When accelerating hard, the frequency of the sound follows the rpm of the engine. So as the car accelerates in 1st gear & upshifts to 2nd, I hear the sound speed up, pause briefly when the gear is changed to 2nd, the sound slower than it was in 1st, and then speed up again as the car continues to accelerate. This happens when accelerating in all gears.
4. 1300 miles on the car.
5. The radio & climate control is turned off when I do this.
I'm thinking this is coming from the DSG transmission. Is this normal? Anyone else with DSG hear this? Ideas? Thanks!

It may not be the DSG
Most of the DSG is on the drivers side, the passenger side has the engine-driven accessories like the AC, alternator and power steering pump.

I agree. That does not sound like DSG behavior
If something strange is happening with it, you'd expect to hear noises during shifts. But it sounds like you are hearing something constantly. It could be anything that runs directly off the engine.

Thanks. But if I accelerate & rev in the "neutral" position I don't hear the sound... does anyone know if the the clutch is still engaged in the neutral position and gears (synchronizers) are not engaged?
I'm guessing everyone else is just getting a normal "voom!" of the engine and none of this extra "busy noise"? Hmmm....

I was told the clutches disengage when in neutral
They also sometimes disengage when coasting at very low speeds. At some point during coasting the computer decides the engine drag should be eliminated and disengages 1st gear. But since you don't hear the noise when accelerating normally, it doesn't sound like it is something that is dependent upon whether the DSG clutches are engaged or not.
To cover the bases, have the dealer check the fluid in the DSG. Low fluid levels have been the culprit in weird noises in several instances according to the tech at my dealer (I had an issue with hearing a wierd chirping noise during 1-2 and 2-1 shifts).
When you say the "frequency" changes, do you mean the occurences/sec or the sound frequency?

Re: I was told the clutches disengage when in neutral
By frequency I mean occurences/sec. So the faster the engine the faster the occurences.
Well I called and scheduled with the service department for next week; I'll mention your DSG fluid suggestion (for the wet clutch?). Sure to have some interesting stories...

Might be the rocker/lifter combo. I had the same noise at 1600 miles...
and the rocker/lifter failed, wiping out the cam.
Car was in the shop for almost three weeks waiting for parts.
That was about 5000 miles ago.
The car has been trouble-free since then and runs great.

Errrrr ... Is there a sound worse than that of gears protesting as you miss-shift 3rd-to-4th at WOT?
