When I come to a stop in my T6 at a light or in my driveway, etc., the car pulsates annoyingly... The car is just shy of 75K miles. I took it in for service and forgot to mention it to the dealer. The dealer did notice it anyhow, and said that it would clean the throttle plate... and to "keep an eye on it for a few weeks." It didn't go away yet and it happens if the car has the A/C on or not....

Any ideas on specific causes/fixes, what I should tell dealer, or relevant service bulletins I should be aware of? Thanks!

could it possibly be a motormount? had a rough idle and the mechanic replaced the top motormount...problem solved.

Thanks for the reply. Replaced the motor mount already. The dealer "cleaned the throttle plate" and that didn't do anything. I am taking it in for diagnostics in about a week. While there is a specific service bulletin on erratic idle, the dealer says that they are going to look at other service bulletins and alot of fixes so I am in for alot of visits and diagnostic bills before the dealer is going to address the problem...

Hope for a positive outcome,
