2017 M6 complete power loss

[jaf30]

I have a weird issue where occasionally my M6 completely loses power for 2-4 seconds before recovering. It feels like the car has jumped out of gear.

This only seems to occur when accelerating off a roundabout. It just so happens that it's the same roundabout every time, but this is likely a coincidence.

Things I've noticed when this happens:
After leaving roundabout, starting to accelerate to near wide open throttle.
Every time I've checked, the car has been in 3rd gear at about 3,500-4,000 RPM.
Engine holds its revs during the power loss.
Not traction control - no light on dash to suggest this.
No error codes in ISTA whatsoever.

Other than this one occasional issue, the car runs perfectly - No rough idle, smooth power delivery throughout the rev range. My current thoughts are that a clutch may be on its way out.

Not sure if anyone else has had a similar experience who could shine some light on this?

I appreciate this is the M5 forum, but as the drivetrain on the M6 is effectively the same, I thought I'd ask here as well.

Car is at 71k miles. Fully up-to-date with servicing.

Kind of sounds like the DCT is low on fluid to me...sloshing back and forth.

I'll check the level this weekend - a DCT oil and filter change is at the top of my maintenance list right now.
