BMW SERVICE ACTION TO REPLACE YOUR VEHICLE'S OXYGEN SENSORS AND UPDATE THE ENGINE CONTROL MODULE SOFflIVARE

Dear valued BMW Owner:

BMW has become aware of incidents of premature wear of oxygen sensors in certain 1996 BMW 31811, 3181, 318is, 318iC and Z3 vehicles with 1.9 liter engines.

In order to prevent this situation from occurring on your vehicle, BMW is conducting a Service Action. We are asking you as the owner of an affected vehicle to contact your Authorized BMW center at your earliest convenience to have the repair performed.
