SUBJECT
M57Y - FC 4BC3 Exhaust Gas Temperature Controller, Plausibility
MODEL
E70 and E90 with M57Y
SITUATION
During diagnosis, the fault code 4BC3 (4BC3 exhaust gas temperature controller, plausibility) is stored in the DDE.
CAUSE
This fault code is generated due to a software calibration error in the DDE.
INFORMATION
Do not replace any parts. Reprogram the DDE with ISTA/P 2.39.3 or higher.
Note:
The DDE will not come up as needing programming on an E70 with an I-level of E070-10-03-5XX with 2.39.3. The DDE will need to be manually
selected for programming in the Action List screen before continuing with the Measures plan.
