Two problems related to air bag light on have been reported for the 2004 BMW 330. The most recently reported issues are listed below.
Takata recall-I've been going round and round with BMW USA and hendrick motors in charlotte, nc since Dec. 2015 trying to get info on when they are going to fix my death trap. I just learned today on this site that my car is priority 1 in high humidity area which charlotte certainly is. Plus the air bag lights have been on since Dec and reported to them and this is the low profile sport model car that is a bumpy ride. I was told in Jan by BMW that an interim bag was sent to NJ specifically for my car, but hendrick clams they no nothing about it. , they have my info and every time I call to see when they will have parts for the recall I get the same insppid blow off, we don't know anything but we'll call you as soon as we do. I just received a letter from BMW saying the parts are ready to call and make appt to replace and hendrick says they don't have yet they are on order should be 2 weeks but they cannot confirm the date, no one knows or has any info what so ever so don't bother us any more. I guarantee that priority had been given to any car that was on their lot for resale!.
