My '10 V6 TDI has an occasional odd feel on the highway, at 60+ mph.

It feels like the car is hesitating a bit, intermittently.

Or, it could be a slight hop in the ride...maybe a wheel out of round, or unbalanced. Tires are relatively new 19" Conti DWS.

I can't tell which it is...

Happens on all kinds of roads.

No CEL on the dash, no codes from VCDS.

Thoughts appreciated!

Happens only on constant light throttle. Goes away when coasting or on acceleration. (Rules out wheels/tires) Tires and wheels are cool (brakes aren't binding).

Consistent, will happen over a long drive, so it's not regen.

Thoughts appreciated!

Have you changed the fuel filter recently? Other than that could be injector or injection pump going. Have you ran any fuel injection cleaner through the system.
