01 05 25_G12 G30 HT COOLANT EXP TANK BREATHING LINE/PIPE EXT LTD WTY 10 YRS/120,000 MILES

This coverage described above applies to the
specific vehicle (VIN), it is transferrable to the
subsequent owners, and is subject to the same
vehicle eligibility requirements, limitations, and
exclusion criteria that applies to the BMW New
Vehicle Limited Warranty for Passenger Cars
and Light Trucks.

Note: This bulletin is notice of a limited warranty extension. This is NOT a notice of a Recall or Service
Action.
There is no immediate repair required unless the BMW vehicle is currently experiencing this problem.
Customer Notification Letter
Even though this is NOT a Recall, BMW NA is sending VIN-specific customer notification letters.

CAUSE
Over time, this breathing line / pipe's (Items #4 and #3 shown above) plastic quick release connector may
become brittle, and in some instances crack and break off, this could result with a coolant leak.
Should this occur, a corresponding Check Control Message (CCM) stating to "Top up coolant, the coolant level
in the expansion tank is below the minimum" could display.
There may also be traces of the leaking coolant in the engine compartment and beneath the vehicle.
Note: To replace this hose on the G12 (740Le Sedan) and G30 (530e Sedans) vehicle models, removing and
installing the water pump is required for access. Coolant pump replacement, if required, is not included under
this extended coverage, please advised and work with the customer accordingly.

CORRECTION
Follow the instructions in the PROCEDURE section.

PROCEDURE
If a vehicle listed above arrives at your center with the issue described in this Service Information Bulletin,
perform the corresponding diagnosis and when it determined to be applicable, replace the coolant pipe from
cylinder head to the expansion tank.
Any other required coolant system-related repairs are not covered under this ELW coverage, for example the
water pump. When applicable, invoiced these items on the repair order separately, and review for other
coverage that may apply.
Warning! Risk of scalding: Carry out the repair work on the cooling system only when the engine has cooled
down.

Important: Life-time coolant filling - Never reuse used coolant!
Installation note: Only use prescribed coolant that applies to the vehicle! Observe the mixture ratio!
For cooling system disassembly/replacement work related to plastic and/or rubber components only where a
partial quantity of coolant is drained, new coolant must be used to replenish the amount that was drained, up to
the top up/full level. DO NOT OVERFILL THE COOLANT SYSTEM.
Other Cooling System Issues And Repairs
This ELW specifically applies to the coolant system’s expansion tank breathing line/pipe, however, these
vehicles may arrive at your center with other coolant system component issues that are beyond the scope of
this extended warranty coverage, for example, the water pump.
It is important to identify these other situations during the vehicle’s RO write-up. Then, if the New Vehicle
Limited Warranty coverage period has expired, your center can proactively advise the customer that the
diagnosis, and repair of these other cooling system issues do not qualify for coverage.
Important Warning for Working on the High-Voltage (HV) Systems on BMW Group PHEVs
740Le xDrive Sedans, 530e Sedans, and 530e xDrive Sedans
Only properly trained personnel, who passed all applicable HV Technical Training Courses, should
perform repairs which require disconnecting, or removal of High Voltage battery components on any
Hybrid or Electric Vehicle. Work performed on High Voltage systems by unqualified persons may result
in severe injury or damage to the vehicle. Additional safety information is found in Repair Instruction 61
00… “Observe safety instructions when handling electric vehicles”.
