Hello! First post herešŸ˜

I own a FL DCT with 24.000km. I'm noticing some problems while accelerating in 8th gear the clutch it's like slipping/ the revs doesn't go smoot

Just wanted to know if someone experienced the same problem or do you know something about it.

It only does it in 8th gear, on 7-6-5... just perfect when you accelerate. It's only the 8th gear that it's like slipping the clutch ( I don't feel any lose of power, only the sound and the rpm chaging weird)
 
I wouldn't really floor it on such low RPMs on 8th gear... it's more like a cruising gear. But I am impressed that the car does not downshift, that seems like the issue to me.

I wasn' flooring it, maybe 50% of throttle, just the point before it does a downshift. I went this week to the dealership and they saw that the car came with low oil level in the DCT actuators (only in that part of the gearbox). They are going to do a DCT oil change and "reset" the actuators to see if it was the problem

I have the same problem, if you solve it please post here de solution
 
In auto mode the ECU makes decision on gear choices for engine load, speed of vehicle, and throttle position; you can't really "lug" the engine or over-torque the tranny cluches unless something's amiss. Low fluid could be the culprit.
