Production Date
Affected Option Code / Engine
SITUATION
Coolant leaking from the engine compartment. Traces of coolant leaking from the expansion tank of the low
temperature cooling system.
Coolant in the low temperature cooling circuit may
also have an acrid smell and discoloration (1).
CAUSE
Aluminum corrosion in the charge air intercoolers, or in the radiator for the low temperature cooling is
causing an unfavorable chemical reaction to the coolant.
CORRECTION
Replace the radiator and both charge air coolers for the low temperature cooling circuit. Allow all the coolant
in the system to drain during repairs (do not clamp off hoses).
PROCEDURE
1. Replace the low temperature radiator.
Refer to Repair Instruction 17 11 006 “Remove and install/ replace low temperature cooler”.
2. Replace the left charge air cooler.
Refer to Repair Instruction 17 51 001 “Removing and installing/replacing the left charge air
cooler”.
3. Replace the right charge air cooler.

Refer to Repair Instruction 17 51 002 “Removing and installing/replacing the right charge
air cooler”.
4. Refill and bleed the low temperature cooling system.
Refer to Repair Instruction 17 00 040 “Bleed the cooling system and check for water
tightness with the special tool (coolant circuit for low temperature)”.
5. Test drive the vehicle for one hour (10 FRU) so that the engine is subjected to many load changes and
coolant system activation cycles.
6. After the test drive, let the engine idle (with proper ventilation) for one more hour (1 FRU to monitor only).
7. Drain the low temp cooling system again and refill with new coolant.
Refer to Repair Instruction 17 00 011 “Draining and topping up the coolant for the lowtemperature circuit”.

temperature circuit (17 00 580) procedure (after test drive
and idling)
If you are using a Main labor code for another repair, use the Plus code labor operation 17 51 505 instead of
17 51 005.
Refer to AIR for the corresponding flat rate unit (FRU) allowances.
Work time labor operation codes 17 99 000, 11 99 000 and 00 50 000 are not considered Main labor
operations. Also, since the work time FRU allowances to be claimed are specified, separate punch times are
not required. However, they still require an explanation on the repair order and in the claim comments
section.
And:
Sublet – Bulk Materials
Sublet Code 4
See sublet
reimbursement
calculation below
Reimbursement for replacing the drained quantity of
antifreeze/coolant (Bulk container reference 82 14 1
467 704, one gallon container. Do not use this part
number for claim submission)
Sublet calculation: BMW antifreeze/coolant (1 gallon bulk container reference P/N 82 14 1 467 704) for
approximately 4 liter (8 liters total) that is needed for this repair (50/50 mixture) at dealer net plus your
center’s handling.
Enter this material cost in sublet and itemize the amount on the repair order and in the claim comments
section.
Overlapping Labor Procedure – Other Repairs
If invoicing the AIR flat rate labor operation codes for other repair work results in overlapping labor, for those
flat rate labor operations that are affected, you are able to:
Replace the stated AIR FRU allowance with a reduced FRU value to eliminate the overlapping
labor.
For help in identifying the overlapping labor, please refer to the AIR FRU Plausibility Check (Overlapping
Labor Tool) that is located in the AIR Client.
Eligible other repair work being claimed under a different defect code will require separate punch times.
On the repair order and in the claim comment section, please identify and itemize those labor operations
being claimed with a reduced FRU value.
