The 1991 BMW 3 Series has 3 recalls, the most serious affecting 318i, 318iC, and 318iS models where the throttle can stick open in extreme cold, leaving the engine unable to return to idle when the driver lifts off the accelerator.
On certain 318i and 318iS models equipped with an airbag, the knee bolster can press against the lower steering column trim cover during a frontal collision, blocking the steering column from moving forward the way it is designed to. That movement is part of how the column absorbs impact energy, so if it is obstructed, the driver faces a greater risk of injury. On 325i models, a loose ground screw in the windshield wiper switch can cause the wipers and washers to behave erratically, reducing visibility in rain or snow when they are needed most.

What can fail
In cold weather below -10°C, moisture from the crankcase ventilation system can freeze at the throttle housing, blocking the throttle plate from closing fully when you release the accelerator. This may cause slow deceleration or higher idle speed.
What the fix does
The throttle housing will be replaced with a heated version and the crankcase vent will be rerouted to prevent freezing.
