335i brake fluid change?

My 335i is bothering me to change the brake fluid, but I checked the brake fluid and it looks really clean. Do I actually have to change it? It's possible that it was changed by the previous owner (brakes were all done by the dealer recently he said) and just not reset but I doubt it.

I change the brake fluid the poor man's way every two years. With a turkey baster I suck out the brake fluid in the master cylinder and replace it with fresh fluid. Drive the car around for a while and do it again a week later. Not a perfect solution but cheap and easy to do.

I highly recommend changing the brake fluid at the recommended intervals. Brake fluid absorbs water which causes it to break down and makes it no longer suited to be used in a hydraulic system. Also heat can break down the brake fluid. If the previous owner had the brakes serviced at a dealer id assume they would reset the reminder and it cant hurt to do it anyways. The procedure i do it suck as much as you can out of the master cylinder and replace it with new fluid. Then start with the R/R, L/R, R/F, L/F
Side note, make sure you use DOT4 fluid and not DOT3

This method really won't do much, as the fluid that has been exposed to heat and other harsh conditions is the fluid that's in the lines. Brake fluid doesn't "circulate" like power steering fluid or coolant. This is why the fluid in the reservoir generally looks pretty clean. You have to bleed the lines to really have any effect.
