This bulletin applies to 2016 BMW 228i xDrive vehicles. A fault code 1D2008 may be stored in the DME and the service engine soon light is on.
The fault code refers to the map thermostat jammed open. There may also be a complaint of low heat output with lower outside temperatures.
During engine warmup, the engine coolant does not reach operating temperature within the DME’s allowable time frame. This is caused by either a faulty thermostat inside the transmission oil heat exchanger or a faulty engine characteristic map thermostat.
Owners of 2017-2019 GMC Acadia vehicles may comment about the SES light on, or the engine may have a slight noise coming from the front of the engine’s belt area. The noise may or may not be present when it comes into the shop.
This bulletin applies to 2018-2019 Chevy Traverse and Equinox, 2019 Blazer, 2017-2019 Cruze and Malibu vehicles, all equipped with a GF9T 45/50/60/65 transmission. A “rotational click” noise may be heard after the engine is shut off.
This bulletin applies to 2017 Nissan LEAF vehicles that stop charging before being completely charged and DTCs B2840 (power delivery module), P3170 (on-board charger) and P3171 (on-board charger) are stored.

The brake control relay with bracket should not be replaced as part of this bulletin. It will be necessary to reprogram the PCM with software version 14.00.019 or later using Techstream 2.0 or Techstream LITE.
