what is this vibration?

[reddog]

hay all, iv got some vibration in my steering.(not to server, but noticeable, and a little worrying)

it is only there under light throttle/no throttle...hard throttle seems to be gone.

it only happens +80kmh below 80 it isn't noticeable.

.....

iv swaped by rims around(back to front), so i think i can cross them off the list.

07 jetta diesel, with DSG gear box.

....

any suggestions?

You could get the wheels balanced and a wheel alignment and see how that goes.

yeah id go the wheel balance and alignment. Made mine wayyy smoother (Golf). Another thing is the diesel may be vibrating, ie the motor might be in synch with the natural harmonics of the body etc, and just starting to vibe everything. Can happen. If i idle at about 1050rpm and get it just right the whole car shakes because of this(i think). Naturaly i dont do it on purpose.
