SUBJECT

Left Side Engine Mount Broken

February 2015
Technical Service

SB-10057529-2505

MODEL

I01 (i3 and i3 REx)
SITUATION

The left side motor mount or motor mount support has failed. As a result, the electric drivetrain moves excessively
in the chassis. A banging noise can be heard from the rear of the vehicle during load reversals. In addition, the
vehicle may experience a Drivetrain Malfunction CCM or other electrical drivetrain failures.
NOTE:
If this failure is present, the vehicle should not be driven, as additional consequential damage could result.
CAUSE

The motor mount or motor mount support is damaged due to excessive shock to the driveline, such as a sudden
loss of traction or underbody impact, during acceleration.
PROCEDURE

Only properly trained personnel, who have passed all applicable technical training courses, should perform
any maintenance or repairs on any Hybrid or Electric Vehicle. Work performed by unqualified persons
may result in severe injury or damage to the vehicle. Additional information may be found in REP 61 00…
Observe safety instructions when handling electric vehicles.
1. De-energize the vehicle per REP 61 25 900 (De-energizing the high voltage system).
2. Replace the left and right side motor mount support, motor mount, and securing bolt per REP 22 11 165.
a. To line up the holes in the motor mount and motor mount support, insert an 11 mm drill bit to ensure
proper alignment prior to installing the bolt.
3. For vehicles produced up to 6/2/14, replace the left and right side axle shafts per REP 33 22 000 and 33 22
002.
4. Replace the two AC lines secured to the AC compressor. Refer to REP 64 52… for notes related to working
on and opening the AC system.
5. Inspect the ground cable that runs from the right side motor mount support to the chassis for
stretching/damage. Replace as needed (BEV only).
6. Inspect the HV cable that runs between the REME and KLE for possible insulation damage. Replace as
needed (REx only).
7. Inspect the underbody V-brace beneath the drivetrain for possible damage. Replace as needed.
8. Inspect the wiring harnesses running along the bulkhead in front of the drivetrain. If any wiring damage is
present, submit a PuMA case for further assistance.
9. Inspect all fuel lines and replace any that have been damaged (REx only).
10. Inspect the 12V electrical connectors on top of the KLE. If any of these connectors are damaged, replace the

KLE. Then inspect the EME in the area where it contacted the KLE. If the EME is damaged, it must also be
replaced.
NOTE: Prior to replacing any HV components, refer to SI B00 03 06 to determine if a TC PuMA case is required.

Sublet – Bulk Materials

Sublet Code 4

Reimbursement for the repair-related
See sublet reimbursement
bulk materials (Please, do not use part
calculation below
numbers for claim submission)

Sublet reimbursement calculation for claiming the used quantities of repair-related bulk materials (BMW part
numbers) is at dealer net plus handling.
Enter this material cost in sublet and itemize the amount in the claim comment section.
Other Repairs - Consequential
As outlined in the Procedure section, when additional work and/or parts are required as a direct result of this issue,
including the applicable “non-overlapping” labor operations listed in KSD2, claim these items under the defect
code listed above.
Overlapping Labor
If invoicing other KSD2 flat rate labor operation codes for the additional work results in overlapping labor being
claim, invoice work time labor operation 00 50 000 for the additional time (FRU) minus the overlap instead.
On the repair and in the claim comment section, please identify the labor operation labor operation code(s) 00 50
000 replaces and itemize claimed FRU amount.
Even though work time labor operation code 00 50 000 ends in “000”, it is not considered a Main labor operation.
Also, since work time labor operation 00 50 000 is an extension of another repair, separate punch time(s) are not
required.
Additional Repairs requiring Programming /Encoding
If a vehicle control module or component was working properly and/or had no related faults stored prior to vehicle
programming and it fails to program correctly and/or requires initialization, this additional work must be claimed
with separate labor operations under the defect code listed above, refer to KSD2.
Repairs to address control modules and/or components with pre-existing conditions are not eligible to be claimed
under the defect code listed in this bulletin.
