Publication date: 2017-11-01Reference number: SI B64 06 17
AIR CONDITIONING COOLING IS INSUFFICIENT
TECHNICAL SERVICE BULLETIN
| BMW: | G12 (7 Series); G30 (5 Series Sedan); Vehicles with B46O or B48 or B58M engine; Vehicles produced September 01, 2015 to March 31 2017 |
SITUATION
There is insufficient or no cooling from the air-conditioner during high ambient temperatures. There also may be irregular A/C air flow from vents.
The following fault code is stored in the IHKA (Integrated Heating and Air-Conditioning Automatic): 80120A "Air conditioning compressor: Shut-down due to excess pressure in refrigerant circuit"
CAUSE
Gel formation and obstruction in the coolant circuit is caused by a reaction between the engine coolant fluid and flux residue from the WCC (Water Colling Condenser).
CORRECTION
After elimination of other possibilities, replace:
- Low-temperature radiator
- Intake system with charge air cooler
- Water Cooling Condenser (WCC).
- Renew coolant fluid (Anti-freeze).
PROCEDURE
For conditions that are similar to the situation described above with Fault code in IHKA: 80120A "Air conditioning compressor: Shut-down due to excess pressure in refrigerant circuit" stored, continue to the next step below.
If low-temperature circuit coolant is not low or leaking and refrigeration system is not low or leaking, continue below to step 1.
- Completely drain all coolant from the low-temperature circuit and dispose properly based on your local regulations.
- Evacuate the refrigeration circuit.
- Replace the AC Condenser WCC with the new part specified below. Refer to ISTA 64 53 550 "Removing and installing or replacing capacitor for heating and air conditioning system".
- Replace the low-temperature radiator with new part specified below. Refer to ISTA REP 17 11 006 "Remove and install/ replace low temperature cooler".
- Replace the intake system with charge air cooler with new part listed below. Refer to ISTA REP 11 61 050 "Removing and installing the intake plenum". These parts are different based on which engine is installed.
- Refill coolant circuit with new coolant refer to Operating Fluids in TIS Group 17; refer to ISTA REP 17 00 011/580 (Inclusive labor operation) "Draining and topping up coolant circuit for low temperature".NOTE: Do not reuse drained coolant from the radiator.
- Refill the A/C refrigerant.
- Test A/C system for proper cooling behavior.

Diagnosis
| Labor Operation: | Labor Allowance: | Description: |
|---|---|---|
| 00 00 006 | Refer to KSD2 | Performing "vehicle test" (with vehicle diagnosis system - checking faults) (Main work) |
| Or: | ||
| 00 00 556 | Refer to KSD2 | Performing "vehicle test" (with vehicle diagnosis system - checking faults) (Plus work) |
| And: | ||
| 61 21 528 | Refer to KSD2 | Connect an approved battery charger/power supply (indicated in KSD 2 as Charging battery) |
| And, as needed: | ||
| 64 99 000 | Work time (WT) | Work time for checking the function of the conditioning system |
If you are using a Main labor code for another repair, use the Plus code labor operation 00 00 556 instead of 00 00 006.
Work time labor operation code 64 99 000 is not considered a Main labor operation; however, it does require an individual punch time and an explanation on the repair order and in the claim comments section.
Claim the diagnosis above, one-time, with the items performed below as applicable:
| Defect Code: | 1711007200 |
| Labor Operation: | Labor Allowance: | Description: |
|---|---|---|
| 17 11 576** | Refer to KSD2 | Remove and install/replace low temperature cooler |
| 11 61 550** | Refer to KSD2 | Removing and installing intake manifold |
And:
| Defect Code: | 6453021500 |
| Labor Operation: | Labor Allowance: | Description: |
|---|---|---|
| 64 50 510 | Refer to KSD2 | Discharging, evacuating and filling air conditioner |
| And: | ||
| 64 53 551** | Refer to KSD2 | Removing and installing or replacing condenser (with drier) of air conditioner |
Refer to KSD2/AIR for the corresponding flat rate unit (FRU) allowance.
And, as needed:
Sublet - Bulk Materials
| Sublet Code 4 | See sublet reimbursement calculation below | Reimbursement for the repair-related bulk materials (excluding R1234yf) , please, do not use these part numbers for claim submission |
Sublet reimbursement calculation for claiming repair-related bulk materials (eligible BMW part numbers) is at dealer net price for the "used quantities" plus your center's handling.
Enter this material cost in sublet and itemize the amount on the repair order and in claim comment section.
Overlapping Labor Procedure - Required
If invoicing the KSD2 flat rate labor operation codes for the above repairs*** and other repair work results in overlapping labor, for those flat rate labor operations that are affected, you can now:
- Replace the stated KSD2 "FRU allowance" with a "reduced FRU value" to eliminate the overlapping labor.
**Specifically for this bulletin, flat rate labor operations 17 00 580, 17 11 535, 51 64 535 and 51 47 500 are inclusive to two or more of the labor operation listed in this bulletin. Other FRU allowance reductions may also be required.
For help in identifying other 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."
Other Repairs
If other or additional work is performed as a result of diagnosing the coolant and air conditioning systems:
- When covered under an applicable limited warranty, claim this other or additional repair work using the applicable defect code and labor operations in KSD2/AIR.
