Hi saflang,
finally someone like me.
I have the same and i got the following changed by my dealer: rims, tires, 4 front Control arms but the vibration is still noticable in 7th gear between 2k and 3 k rpm.
see my post in that matter. i will paste it here.
My dealer replaced the parts under warranty but they think it is rather the drive shaft or the diff which is causing vibration not the engine.
regards
sh
