The rough running sound when cold is normal, it's a peculiarity of the 8 individual throttle butterflies I believe.

However, I have a Q for those with DCT: do you find that the car accelerates less smoothly when cold or even when just warm? ie when I have driven for a while, then stop the engine for a few minutes or so eg when I go the shops or pick up my son from school, I find that for a few minutes upon restarting the acceleration is a bit "gluggy". Is this normal?
