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.

Fault Code 1D2008 Stored in DME: This Service Information Bulletin (Revision 5) replaces SI B12 33 14 dated February 2016. The Service Engine Soon light is on. There may also be a complaint of low heat output with lower outside temperatures.
