BMW service bulletin · NHTSA ID 10148328 · May 2014
What it covers
A service bulletin tells BMW technicians how to diagnose or fix a known issue. It is not a recall: a repair under a bulletin is normally paid by the owner unless the car is still under warranty or a warranty extension applies.
Cleaning Excess Butyl from RHT Roof Shells. Butyl adhesive is used to secure the seals of the retractable hardtop (RHT) to the steel roof shell panels. Particularly at high ambient temperatures, if excess butyl is present, it may start to seep out from between the seal and the roof shell.
