when the car in tiptronic mode for hard drive about 1-2mins following is vibration & feels like clutch slip, but then after 10second cool down it will back to normal

Please give me advise WHAT IS WRONG, I m Really sick of this...thanks very much

Bit more info? Vibrating when accelerating? Vibrating when cruising? Is the car tuned? How hard is a hard drive? Sorry man not quite sure what your trying to describe.

yup..Vibrating when accelerating..but the engine was running fine...n yes flash tuned 338kw, continously rev 6k/rpm then shift, imagine how hard will u drive when u race a motorbike

and sorry, eng is not my 1st language but pls help thanks

Check the centre bearing on the tailshaft

Rubber can break away causing shaft to wobble and vibrate

No problem, If its vibrating when accelerating then id probably be looking at your tailshaft or the condition of your sparkplugs (should be 0.8mm gapped) and maybe your coil packs as they can degrade after time.

Also might be a good idea to look at upgrading the transmission especially when you rev it 6k to change all the time

Does the gear indicator flash on the dash when it vibrates or anytime after?

If it comes good after a rest it may be valve springs are they stock ,or you might be cooking the trans fluid revving that hard,

thx for reply, I suspect the tail shaft or gearbox overheated,because when it was vibrating I could feel the engine running fine(boost stable) the feeling is "power cannot transfer to the wheel" would get some pros to have a look!! thanks

thx for reply, yes stock valve springs, do u think the power is over the springs limit?? trans fluid overheat sounds like it :)thx
