It has happened once or twice, but this rarely occurs in my experience. And I've had my car over a year now.

I'm happy with my car so far. Even done some soundproofing to the car so that makes me even happier.

DSG jerkiness and drag will always be there, it's the characteristic of the gearbox but so far I'm okay with it. Surely an automatic transmission will feel smoother no doubt but the quick shifts of the DSG makes it all worth it.

The service center is kind of crap, but I figured since I just drop of the car. My dealings with them is minimal. And I usually book about a month in advance and triple confirmed 2 weeks before and a week before the actual service date.
