Just wonder if anyone in here have experience a hard brake pedal after the car have not been driven for a while, otherwise, the brake system works fine. Going into the dealer soon, just trying to decide if i should bring up this minor issue.

I don't have this problem on my S5 after not driving it for a week, but my A4 used to do that if I didn't drive for at least 3-4 days. This is normally indicative of a very slight vacuum leak, but whether it is actually a problem depends upon how you define "a while".

Its happening about once every 3 starts in the morning, i remember some VW use to have a nitrogen booster on the braking system to assist the brakes if the car lose power. Sometimes the nitrogen leaks out and the part has to be replace.

If it loses pressure in less than 24 hours, that could be abnormal and suggest a slight vacuum leak.

IMO you should absolutely raise it with the dealer. They cannot check if they don't know.

Really? No one has mentioned anything about "stiff ... in the morning"?
I thought we had a childish bunch here (or am I the only one?)

I think someone posted / deleted it by post 3. Guess they thought better of it.
