Only when accelerating hearing this rattling noise (can feel it through pedal also) in all gears arround 1200-1300rpm.
Not every ride hearable at same sound level like this. also hearable when almost standing still and drive slowwwly from a short slope in drive or rear.
Warm or cold weather doesn't matter.
Warm or cold engine doesn't matter.
The sound is already there at low torque.

Anyone got a clue?
it started at 35.000km. now at 39.000km.
visual inspection done at 2 garages already.
The RS is chipped and running at 360hp and 510nm torque.

I had this with a Hyundai Coupe - fortunately it was still under warranty as it needed a new gearbox.

Hmmz and you had any other issues with the gearbox or just the sound? 

Just the sound.  It only occurred under particular load conditions.  There was a long slight rise after a junction on the road home from work, and gentle acceleration up that in third gear always triggered it.
