Cruise hesitation

[904mk7]

For reference the car is dsg with a custom tune stage 3 dsg tune fbo and e30

During cruising speeds under 50mph around 1600rpms and when it's hot (90*+) I get a weird hesitation/bucking when I'm holding speed at that rpm. Any less or any more rpms it goes away. Seems to be about 15% throttle. I logged it and notice the afr's drop to low 11's and 10's.bit doesn't happen Everytime, but enough to be annoying. I'm thinking maybe 02 sensor going? All other times the car is perfect.

Bump. No one has experienced this issue?

I'm thinking that you're in too high of gear at that speed and the bucking you are experiencing is lugging the engine just like it would with a manual trans. Either change to a lower gear or don't give it 15% throttle. Whose DSG tune do you have that it wouldn't downshift to avoid that?
