SITUATION
After engine start, the malfunction indicator lamp (MIL) and Check Control message (ID 29) "Engine fault!
Power loss" are displayed in the instrument cluster.
In addition,

The following fault codes are stored in the Digital Motor Electronics (DME)
Engine runs in failsafe mode
Engine cannot exceed 800 - 1,200 RPMs

Fault code
10170C
And/or:
100213

Control module
DME

Fault code text
Throttle valve, function: Jammed briefly

DME

Throttle valve, function: Sluggish, too slow

Note: The complaint occurs when the vehicle has been left in ambient temperatures of 23°F or below
for an extended period.

CAUSE
Certain unfavorable ambient conditions in combination with a specific driving profile may cause
condensation to form at the throttle valve. The valve can thereby freeze when the vehicle sits for a long
period of time at low outside temperatures.
As a result, after a cold engine start the throttle valve cannot open at all, or only with difficulty.
Note: The closing function of the throttle valve is not impaired in any way.

CORRECTION
Program the vehicle.

PROCEDURE
In the event of a vehicle arrives at your center with the SITUATION described above, proceed as follows:
Perform diagnosis with ISTA.
If the diagnosis carried out in the warm workshop-

Does not identify any "real" fault
Complaint occurred during the engine start
Vehicle had been at a standstill for an extended period at low outside temperatures

The cause of the complaint was most likely a frozen throttle valve.

Check the fault code details of 10170C and/or 100213, If the ambient conditions are as follows, a frozen
solid throttle valve may be assumed:
Ambient temperature
≤ 41 °F (5°C)

Coolant temperature
≤ 140 °F (60°C)

Driving speed
≤ 3 mph (5 km/h)

To rectify the situation, program the vehicle with ISTA 4.20.2 (supports I-level 19-11-530, released midNovember 2019) or higher.
Note: An optimized DME application is available which activates the throttle valve with increased power
several times during an engine start at low ambient temperatures (icebreaker / breakaway function).

WARRANTY INFORMATION
During this workshop visit, the affected vehicle may also show one or more programming and encoding
Technical Campaign repairs open, the programming and encoding procedure may only be invoiced one
time.
Update the vehicle to the required I-level or higher by performing and submitting for one of the open
Technical Campaigns instead. Please be sure to also perform any additional work (before and/or
after) the campaign repairs require and/or close the remaining open programming and encoding
Technical Campaign repairs as outlined in the corresponding Service Information Bulletin.
Only if the above situation does not apply, the BMW software solution is then:
Covered under the terms of the BMW New Vehicle Limited Warranty for Passenger Cars and Light Trucks.
This repair is also covered by the terms State-specific Emissions Warranty (dependent on the vehicle’s
model year, state of registration and its inclusion on the model-specific list of covered components).
Afterwards, it is then covered under the terms of any active and remaining BMW Certified Pre-Owned
Program coverage that applies to the BMW vehicle.

Please claim this consequential control module-related repair work (including performing the IRAP
Control Unit Recovery procedure first as required, refer to the SIB in AIR) under the defect code listed in
this bulletin with the applicable AIR labor operations.
Please explain this additional work (The why and what) on the repair order and in the claim comments
section
For control module failures that occurred prior to performing this programming procedure:

When covered under an applicable limited warranty, claim the applicable test plan and the corresponding
control module-related repair work using the applicable defect code and labor operations in AIR
(including diagnosis with separate punch times).
Other Repairs
If other eligible and covered work is performed as a result of performing the ISTA diagnostics and related
test plans, claim this work with the applicable defect code and the labor operations that are listed in AIR
(including diagnosis with separate punch times).
