SITUATION

Fault 180001 - "Catalytic converter: Efficiency below limit value" is stored in the DME memory.

The Malfunction Indicator Lamp (MIL) is not illuminated.

There are no other faults in memory relating to the fuel system.

CAUSE

DME software diagnostic sensitivity

CORRECTION

After verification of catalytic converter(s) condition, reprogram with specified version of ISTA/P or ISTA NEXT.

PROCEDURE

For conditions that are similar to the situation described:

Perform diagnosis with the latest version of ISTA.
Are there any other faults in the fuel system stored in memory pertaining to:
- high or low fuel pressure?
- oxygen sensors?
- mixture faults?
- engine misfires?
YES - continue diagnosis with ISTA test plan.

NO - go to next step
Perform a visual inspection of the catalytic converter(s) looking for:
External:
- Physical damage
- Excessive thermal discoloration
Internal (with endoscope via removed oxygen sensor before catalytic converter opening):
- Deposits
- Breaks or fusing in honeycomb structure
Is there any consequential damage to a catalytic converter?

YES - replace the catalytic converter.

NO - go to next step.

Program the vehicle using ISTA/P 3.62.0 or ISTA NEXT 4.06.2x or higher to appropriate level shown below:

Model	Target integration level
F22 (2 Series Coupe)	F020-17-07-500 or higher
F23 (2 Series Convertible)
F30 (3 Series Sedan)
F31 (3 Series Sport Wagon)
F32 (4 Series Coupe)
F33 (4 Series Convertible)
F34 (3 Series Gran Turismo)
F36 (4 Series Gran Coupe)
G12 (7 Series)	S15A-17-03-500 or higher
G30 (5 Series Sedan)

Note that ISTA/P 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 ).

For information on programming and coding with ISTA/P, refer to CenterNet/TIS/Technical Documentation/Diagnostics and Programming/Programming Documentation.
