- Summary
- The crankcase ventilation system, vented into the intake tract of the engine at the bellows boot ahead of the throttle housing, allows warm water vapor from the crankcase vent to condense and freeze in the colder bellows boot when the ambient air temperature is 15 degrees fahrenheit or less. The build up of ice can dislodge and move into the throttle housing, preventing the throttle plate from fully closing when the driver releases the gas pedal.
- Consequence
- If the throttle plate is prevented from closing, thereis an increase in idle speed as well as slower than normal deceleration, whichoccurs without prior warning and could result in an accident.
- Remedy
- Replace the throttle housing with a version containing a modified heating system along with rerouting of the cvs hose. This will prevent ice build-up in the intake tract.
- Notes
- System: throttle linkages and control.vehicle description: passenger vehicles.

Vehicles covered
As listed by NHTSA. A recall usually covers only some vehicles of each model and year, often a production date range.
Has your BMW been repaired?
Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.
NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A BMW dealer can also check your VIN. Recall repairs are free.
