SERVICE INFORMATION
This Service Information Bulletin (Revision 7) replaces SI B17 06 17 dated July 2020
What's New:
- Production dates and engine variants added

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
- Replace the low temperature radiator.
- Refer to Repair Instruction 17 11 006 "Remove and install/replace low temperature cooler" .
- Replace the left charge air cooler.
- Refer to Repair Instruction 17 51 001 "Removing and installing/replacing the left charge air cooler" .
- Replace the right charge air cooler.
- Refer to Repair Instruction 17 51 002 "Removing and installing/replacing the right charge air cooler" .
- 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)".
- Test drive the vehicle for one hour (10 FRU) so that the engine is subjected to many load changes and coolant system activation cycles.
- After the test drive, let the engine idle (with proper ventilation) for one more hour (1 FRU to monitor only).
- 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 low-temperature circuit".

SUBLET - BULK MATERIALS (RO AND CLAIM COMMENTS REQUIRED)
| Sublet Code 4 | See the sublet reimbursement calculations below | Reimbursement for the repair-related bulk material (Do not use the BMW part number for claim submission) |
Sublet reimbursement calculation for claiming the applicable repair-related bulk material (BMW part number) is at the dealer net price amount for the proportional quantity used plus your center's handling.
BMW Antifreeze/Coolant: Claim the corresponding sublet dollar amount for the quantity needed to replace what was drained. The one-gallon concentrate part number at the proportional quantity needed for a 50/50 coolant/water solution.
Enter this material cost in sublet and itemize the amount on the repair order and in claim comment 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.
