I hope some of you can help me here.

The car used to be so quiet that you cannot hear much when all the windows and doors are closed.

Suddenly, I can hear wind and road noise when I drive the car today. When going over hump, I can hear some rubbing noise from the door.

I notice the following:

1. The weather here has suddenly changed to about 12deg rather than 20+deg last week
2. The door close assist will close the door but then after a couple of seconds, I can hear a slight gas release sound, the door comes back out a bit. The door is still lock. I do not know this is always the case because I never pay too much attention to it. I might have to adjust the door latch because the door is not closing perfectly althought it is not bad. I do not think the door latch is the problem, even if it is, how can all the door latch has gone wrong suddenly.

Is there anything I need to pay attention to. What can be wrong?

Many thanks....

Michael
