Shuddering S6

[Brian Pleet]

My S6 has been problem free right up to right now @ 100k km.

Last week I felt some hesitation when I hit the gas in 4th at 3,000 RPM,
followed by a shuddering, as if it was trying to catch its breath. Within 3
seconds the shudder was gone and the car took off, as per normal.

A few days later, I started to feel a momentary hesitation even below 2,500
RPM and then the engine would respond and the turbo would kick in normally
at about 3,000 RPM.

Is there anything I can do/check/fix before I take it in to the dealer on
Monday?
