N51 OR N52K IMPORTANT INFORMATION WHEN PROGRAMMING THE DME

TECHNICAL SERVICE BULLETIN

Reference Number(s): SI B 12 02 10, Date of Issue: March 2010

BMW:	All models with the N51 or N52K engines
GROUP:	12 - Engine Electrical Systems

SUBJECT

N51 or N52K Important Information when Programming the DME

SITUATION

After complete vehicle or DME programming (regardless of the ISTA/P version used), the following fault code(s) may occur:

2FA3 - coding missing
2FA4 - incorrect data record

The effect of these faults could be noticed as a loss of acceleration or overall performance.

CAUSE

Under investigation

CORRECTION

It must be ensured that following programming, neither fault code 2FA3 nor 2FA4 remains stored in the DME.

Following programming, the DME fault memory and adaptations should be cleared.

Then cycle the key off and back on, and recheck the DME fault memory again.

If fault code 2FA3 or 2FA4 is still present, work through the test plan in ISTA.

If programming and/or coding is recommended, start ISTA/P and select both the CAS and DME for programming and coding. Recheck to see whether the fault(s) is now able to be cleared.

If the DME needs to be replaced as a result of the diagnostics, a DME TC PuMA Case will need to be created before ordering the replacement part.

NOTE: The vehicle must not be released back to the customer under any circumstances with fault code 2FA3 or 2FA4 stored in the DME.
