Alternator belts should be changed every 36,000 miles (60,000km) for proper maintenance.
We recommend you look at your old belt prior to ordering. In some cases, this belt applies to the later dual spark models. You may be able to confirm the correct belt if the BMW # 12 31 1 341 779 is still legible.
The Continental Ref # 4PK611 should also be visible.
NOTE: Continental Contitech Part numbers are very similar, another way to determine which belt you need is by BMW part # OR length of the belt, which may or may not still be legible on your old belt.
