The 1991 BMW 3 Series has 3 recalls, the most serious affecting 318i, 318iC, and 318iS models: in very cold weather, ice can build up at the throttle and prevent it from closing fully when the driver lifts off the accelerator, leaving the engine unable to return to idle.
On 318i and 318iS models with an airbag, the knee bolster can press against the lower steering column trim cover in a frontal crash, blocking the column from moving forward as designed and raising the risk of driver 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.

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.
