Two problems related to catalytic convertor have been reported for the 1997 BMW 318. The most recently reported issues are listed below.
While driving 65 mph engine check light remained on, and exhaust fumes were coming into the vehicle while the windows were closed. Consumer stated there was a recall on website concerning the catalytic converter oxygen sensor . Not able to locate that information in our data base.
Catalyic failure at <20000 miles seems unusaul. In talking to two dealers, both service departments indicated that the "318's had a problem with the converters that year". Seems to me that if they had a problem, they should fix rather than waiting for it to break, then my having to take time off from work, and rent a car while mine is in for repairs.
