New car delivered today, E350 cdi convertible 2011. Lovely.

But there is a problem.

At low revs, on a steady throttle, it feels like the engine is missing, and the rev counter fluctuates by 100 rpm or so. Its quite annoying.

More acceleration and it goes away and drives fine.

Now, this car was from a used car dealer, and I know I can tell them to stick it if there is a major issue. They are 3 hours away from me.

But I like the car, so will need of course to get it diagnosed, but is there anything anyone knows about?

Cheers
