BMW Z4 known problems

Some of the common problems or complaints about the BMW Z4 are:

On models from the second generation, there are known issues with a badly designed rear bumper vent causing the water to leak into the boot and could potentially destroy some of the various electric modules that are located in the boot.

Engine misfire when the engine is idling caused by a faulty DISA valve. You may also hear a rattling sound arising from the engine.

Rattling sound arising from underneath the car when driving over rough surfaces, or speed bumps caused by a weak flap in the rear section of the exhaust.

The second-generation (2009-present) Roadster, has the folding roof mechanism stored in the boot. This mechanism has a synthetic molding, which is quickly damaged if there is anything left in the boot when attempting to fold down the roof. The most possible damage will be a crack in this molding.
