Just bought my 2007 CPO 335i coupe. I should've noticed when test driving...i experienced bumpy pulsation coming from the rear of the car when braking at high speeds. During the test drive this was exciting a highway at about 65mph. At the time i had assumed it was bumps in the asphault from tractor trailers and as i was so anxious to get on the road with my new toy, i never made mention of it.
1,000 miles later it was getting worse and worse, and my concerns were a worn rotor (not covered under warranty). Fortunantely for me, the caliper was seizing on the rear passenger wheel. It was covered under warranty and since it caused some abnormal wear on the one rotor, i got new pads and rotors for the rear.
