    If memory serves, the maintenance-free belt is applicable to 2004 and later. What may be worth investigating is the changeover that was done to the pulleys and belt in the 1100 series. Yours should have been done, and you should have the ribbed belt.

    Regardless of what BMW or others may say, there's
    no such thing as a "lifetime" on "never needs replacing"
    belt....

    Here's ample info on oilhead belts:

    I think the maintenance free refers to the fact that it needs no re-adjustment during its service life. You still need to replace the belt occasionally.

    My memory is hazy but I recall that there was an update to a belt that didn't require re-tensioning after 6k miles. If so, I think that is a super-cession and should be the only one available. It isn't the same as the Elast belt which became standard in 2004 when the freewheel alternator pulley was introduced.

    Maintenance free is not the same as lifetime, don't confuse the two.

    What the OP's "friend" probably meant was that the belt doesn't stretch, so no readjusting necessary. On the 1998 BMW this is not necessarily the case. After the first 6K the belt needs to be checked for tension.

    No 6k mile retension on the 1100 per this.

    Depends on the actual belt. From your own link (BTW NOT a BMW official document).

    Perhaps you should discuss it with the author, Anton Lagardier.

    What I was going to say! BMW loves to advertise various "service free" items on their cars too -- it's bullshit there as well.
