Original BMW Stopper Bolt for BMW 1 to 7 Series, M2, M3, M4, X1 to X6, and Z4 (2006–2021)

Part number 11-37-8-648-357 is the current Original BMW stopper bolt for the variable valve timing adjustment hardware on four- and six-cylinder BMW 1 to 7 Series, M2, M3, M4, X1 to X6, and Z4 models from 2006–2021. BMW introduced this number in November 2014 and marks it exchangeable retrospectively, so it replaces the earlier 11-37-7-516-306 on older cars as well as current production. Each bolt weighs 39 g.

Original BMW Parts carry a 24-month parts warranty.

Because the new number is backward-compatible, owners of 2006 to 2014 cars who find 11-37-7-516-306 on an old invoice or diagram can use this bolt in its place. BMW applies it across an unusually wide engine spread: the N51, N52, and N52N inline-six, the N20 and N26 four-cylinder, the N55 turbo six, and the S55 in the M2 Competition, M3, and M4. That covers chassis from the E82, E90, and E60 generation through the F22, F30, F32, F10, F06, F01, F15, and F16, plus the E85, E86, and E89 Z4.
