Slight engine vibration - dual-mass flywheel?

[jdp1962]

My engine (2.4V6, with Multitronic box) has a slight vibration at around 1800rpm. It's only at that crank speed, the rest of the time it's smooth as silk. My local garage reckoned it might be the dual-mass flywheel.

Anyone got any thoughts on this, or any ideas how much a replacement flywheel is likely to cost?

I spoke to AMD for my s3 and it goes for about 250 pounds I don't know how much it would be for your model, hope it helps...
