change in brake pedal feel (more effort)

My 2011 M3 last had a brake fluid change over a year ago. The brake pedal travels further before any feel of braking. It is definitely a worse feel than when the car was new.
I took it in to BMW and told them I thought the brake fluid needs to be replaced. They told me the brakes were fine and the next brake fluid change is not for another year (under the BMW maintenance program).

With a high performance car like the M3 I cannot believe they change the brake fluid every two years. I believe the worsening brake pedal feel is attributable to the degradation in brake fluid (If anyone disagrees please let me know).

I am thinking of paying for the change in brake fluid just to get it done now. I have to believe that the brake fluid degrades over time, not just total degradation at the two year mark.

It matters a lot on how and where you drive. Spirited track exercise required fluid changes very frequently. Hot brakes, hot fluids, air incorporation and mushy braking can be very dangerous.
Either your dealer, an INDY or DIY brake work is most likely needed.

Could it be that the brake lines were not properly bled? Meaning that there is some air trapped in them and hence the further travel of the brake pedal.

Brake pedal feel is always awesome after bleeding them. This only lasts for a few months in my experience.
