Continental Contitech Part numbers are very similar. To determine which belt you need use the BMW part # OR length of the belt, which may or may not still be legible on your old belt. 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: There can be confusion regarding the new Continental Contitech Belt PART #’s which have recently been modified (2nd QTR , 2012). There are now 2 Continental Belt Part #’s ending with 611

Continental Contitech specifically designed the Contitech Elastic technology for use on the non-tensioned BMW alternators. Use of any other manufacturers belt will not ensure proper tension over prolonged periods.

Use of other brand belts can lead to
  1. Premature alternator bearing failure due to too tight of a belt tension.
  2. Belt slippage due to too loose of a belt tension.
  • Temperature-stable from -30 to 80 °C
  • Tropicalized - withstands high heat extremes
  • Extremely long service life
  • Conditionally oil-resistant
  • No retensioning necessary

The Continental Contitech elastic ribbed belts are self-tensioning which cuts drive costs considerably.
