When coasting (that is not applying any or little acceleration) at 40 to 60 kl, a knocking noise emanates from the transmission. I have driven another VY II and found the same happened with it.
Holden has tested the transmission in my car and says its normal. The presence of the noise is embarrassing. Passengers (including a Holden mechanic I asked to identify the problem) have noted the noise.
With the exception of the knocking noise noted above, the VY II 6cyl is good to drive. There is sufficient power. The suspension is firm. The trim is good. A good quality 4 sprk stereo is included. With ABS and dual air bags, the car is good value.
Our vy2 has no problems with it. fused ecotec gives plenty of power.
We also have a VY and have an intermittent knocking noise. The car is with a dealer who mentioned there may be some sort of recall on rockers or valve guides... I will post some more news if we think we've solved the problem... Does anyone know of a list of recalls for VY's?
