BMW 3 Series: Engine
Affects BMW 3 Series · 1992–1994 — about 4K vehicles.
The hazard
On certain 318I and 318IS vehicles, under certain conditions, with low ambient temperatures (-10 degrees and colder) and a warmed-up engine, water vapour in the warm air from the crankcase might condense and freeze in the throttle body. This could prevent the throttle plate from closing as the driver releases the gas pedal and might result in loss of vehicle control. Correction: Throttle body heater will be replaced with a modified heater.
