NO COOLING INTERMITTENTLY FROM VENTS
MODEL
G12 (7 Series)

G30 (5 Series)

G32 (6 Series)

F90 (M5)

SITUATION
After a long journey (more than 30 minutes), the customer notices the cooling power is too low or non-existent.
Air exiting the vents is intermittently reduced although the blower setting remains the same.
The fault can occur under the following conditions:


Air Conditioning switched ON



At lower blower speeds



Temperature setting is set lower than 68 degrees Fahrenheit



Outside temperature is greater than 68 degrees Fahrenheit



Journey time of at least 30 minutes

CAUSE
Evaporator icing up

CORRECTION
Reprogram vehicle

PROCEDURE
1. Perform diagnosis with the latest version of ISTA, working through test module, if needed.
2. Is the vehicle Integration Level lower then S15A-18-11-523?
Yes-proceed to Step 3
No- No programming is needed, using ISTA work through test modules to diagnose vehicle.
3. Program the vehicle using ISTA 4.14.1x or higher.

Model

Target integration level

G12, G30, G32, F90

S15A-18-11-523 or higher

Note that ISTA will automatically reprogram and code all programmable control modules that do not have the
latest software.
Always connect a BMW-approved battery charger/power supply (SI B04 23 10 ).

During the same workshop visit, if a vehicle also requires another Technical Campaign or repair that also
includes programming and encoding the control units, the programming procedure may only be invoiced one
time.
Programming and Encoding - Vehicle Control Units
A. The programming procedure automatically reprograms and encodes all vehicle control modules which do not
have the latest software i-level. If one or more control module failures occur “during” this programming
procedure:
• Please claim this “consequential” control module-related repair work under the defect code listed in this

bulletin with the applicable AIR/KSD2 labor operations.
Please explain this additional work (The why and what) on the repair order and in the claim comments section.
B. For control module failures that occurred “prior” to performing this programming procedure:
• When “covered” under an applicable limited warranty, claim this control module-related repair work using the
applicable defect code and labor operations (including diagnosis) in AIR/KSD2.
