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. CAUSE During the engine warm-up the engine coolant does not reach operating temperature within the DME's allowable time limits. This is caused by either a faulty thermostat inside the transmission oil heat exchanger or a faulty engine characteristic map thermostat.

SITUATION
The Service Engine Soon light is on. Fault Code 1D2008: “Map thermostat: jammed open” is stored in the
DME. There may also be a complaint of low heat output with lower outside temperatures.
CAUSE
During the engine warm-up, the engine coolant does not reach operating temperature within the DME’s
allowable time limits.
This is caused by either a faulty thermostat inside the transmission oil heat exchanger or a faulty engine
characteristic map thermostat.
PROCEDURE
Note: The following checking procedure must be performed on a cold engine.
Remove the front underbody protection panel
(tightening torque of screws is 3 Nm) to
access the cooling lines to the transmission oil
heat exchanger (1).
Note: All illustrations were taken on an F30
328xi N20.
Clamp off the outflow hose (1) on the cooler
with special tool 81 64 2 184 117 (SI B04 07
11).

12 33 14_Fault Code 1D2008 Stored in DME
The outflow hose is the softer
(rubber) of the two cooling lines on
the heat exchanger
After clamping, remove the outflow hose from
the heat exchanger (1).
Loosen the cap on the coolant expansion tank
(1).
If any coolant starts leaking out of the
transmission heat exchanger (1), the
internal thermostat is jammed and the heat
exchanger will need to be replaced.
Follow Repair Instruction RA 17 22 010,
“Removing and installing/replacing
transmission oil cooler for automatic
transmission (N20, N26, N55).”
