sputter when accelerating
I have a 2010 VW CC. automatic 2.0 Turbo 4cylinder. 52k miles

just last week I noticed that when im doing...like 40mph..and I accelerate to 55..i get some sputtering. it seems to ONLY do it when already cruising. so when I take off at 0mph to 35 or 45 it doesn't sputter.. I bought the car with 22k miles from as a Certified used car. I have ONLY run NON ethanol Premium in the car since I have had it.

other than that, the car starts right up and runs smooth. I have not noticed a decrease in fuel efficiency. it IS due for service and oil change.

any help or thoughts would be greatly appreciated.

RE: sputter when accelerating
All fuel sold in the USA has some ethanol in it and it's supposed to be less than 10% unless posted other wise.

I have heard of a few issues with "lean misfire" under light throttle and also some problems with the turbo waste gate linkage starting to stick with age. Hard to say from this end. Have you tried any injection system cleaner? Does your owner's manual ask for a plug change at 50k on the turbo engine? (most are 100k these days) When was the last time you change the filters? Could be as simple as minor fuel starvation due to a partially clogged fuel filter.

Let us know how you make out as it may help others reading the furum.

thank you for your response. I will try the things you mentioned. I am sure when I take it in for service they will identify the issue.
