Yes.. so the time has come.
My 2010 PTT have become sluggish. Numerous treads on this, but nothing that
gets my pulse below 150 again.

Had her in for a 100.000km maintenance the other day.
Dropped the PDK for a seal change and a new flywheel.
New spark plugs as well.

I feel some kind of hesitation and surge under acceleration.
Also there might be some loss of power.

The sluggish acceleration is most noticeable when not in sport/sport+, and/
or high gears.

No CEL
No codes
Engine burns oil, and have always done so.
Sooty tailpipes. Specially on the drivers side.
New fuel pump april 2014.

Any thoughts ?
Some sensor telling the ECU to pump more fuel into the driver side bank .. ?

Dealer lost when no codes.

Cleaned MAP.
Car running better, but still sluggish in high gears.
Noticable specially in comfort mode.

your post was not clear to me [i,m old] did the problem happen after the repairs ? do you think it was all of a sudden or gradual loss of power ?

andreashanger

Sorry.
Problems began before the change of flywheel and plugs.

No direct loss of power, but it feels like running on a slippery road with occational wheelspin.

I'm thinking coil packs or some sensor.

if your RPM,S are going up and you are not really picking up speed it sounds like a transmission problem slipping .....show the dealer/mechanic the problem with you driving it.

No slip in tranny, rpm stable, just feels like its slipping.
