I've noticed recently when bringing the car to a stop in neutral, just as it's almost stationary the engine starts to shudder as if it were about to stall. If I dip the clutch and return to neutral it goes away. Also the revs usually pick up a small amount, maybe 100 rpm but a noticeable swing on the needle even though I'm not on the throttle or in gear.
If I slow the car down in gear and then brake to a stop with the clutch dipped it gets around the issue, it's only when the car is in neutral and braking to a gentle stop and low speed and doesn't occur consistently.
Any one experience anything similar or have any ideas what the issue is?
The car is an 07 2.0 TDi (140) S-Line with 44,500 due it's third service in about 4k
