Default 14 S8 4.0tt Turbo Lag

I recently purchased a 2014 S8 and just wondering if anyone else has found a good solution for the turbo lag. I absolutely love this car, and have little complaints but the turbo lag when you initially accelerate while driving conservatively drives me crazy. Has anyone found a reasonable and simple solution for this?
Thank you in advance for your input.

I don’t have any turbo lag, but I have the engine/transmission set to “dynamic “. You may want to check your setting. I love the color of your car! Mike

I have no lag on mine either. You may want to get your car checked out incase you are developing issues

Given the hot V design, about as low lag as you will find, and a whole lot of power quickly for me. If you truly want no lag, too late now but there is the quasi unicorn D4 W12 that also takes big depreciation hits used. My D3 W12 was certainly, right there, right now with torque way low down in RPM's. Also maybe go into the DriveSelect settings and change them for engine & tranny.

Yeah, like the others, turbo lag is not normally an issue at all with this motor.

Default I have a 14 S8

And I know what you mean - in “comfort mode” it’s a bit sluggish to respond to throttle and then you’ll get kind of a big rush in power eventually. As stated above try in dynamic mode and see if you have turbo lag then.

I appreciate the responses from everyone. It could be that I'm just being overly picky. I usually drive it in dynamic sport mode, it just seems that initially starting out there is a fine line between slowly accelerating (which has a slight delay) and getting on it aggressively.
It's definitely an amazing car, which I have zero complaints!!

Thank you in advance for your input.

1.) Absolutely beautiful car!!!

2.) As others have stated, should be very little lag on this motor due to its design. Having said that, i believe i read somewhere that on cold start and for first 5 - 10 minutes of driving, I believe the engine has a safety feature which essentially reigns in the turbos until everything has reached optimal operating temperature. Maybe this is the "lag" you are experiencing? Does it happen all the time or just within first 5 - 10 minutes of driving after car has been sitting?
