Stall limps.
I have a 2003 325i when coming to a stop with the foot on the brakes (lightly), as the transmission downshifts I can hear a thud/clunk coming from the rear end of my car along with a increase in the rpm's. I also hear it as soon as I let off my foot of the gas pedal or accelerate causing my car to not drive properly and my transmission to hit my suspension very hard. So, I've searched this issue and other BMW forums and found that other people had the same complaints and this exact problem which is dangerous & very scary.
Driving the car the front driver wheel axial system fell off where the ball bearing held the wheel on 3/4" ball bearings fell off the car, and the other side was ready to fall apart as well I was driving and as I turned into the auto shop driveway the wheel fell apart good thing my teenage daughter was not driving it on the highway or expressway.
Bilstein is a maker of aftermarket shocks. The rear bilstein shocks for the BMW 3-series from 1999-2006 are prone to premature failure. Bilstein has updated the part twice in an effort to fix the problem, but the shocks continually fail. There are thousands of premature failures of these shocks in the last five years. Rear shock failure creates dangerous handling problems, loss of braking performance, and damage to the vehicle. Stop bilstein from selling any more of these dangerous shocks! I have had nine rear shocks fail, and bilstein keeps sending out the same part as part of the lifetime warranty.
Stalling, electrical issues, dead batteries, swerving.
