Good morning, everyone.
My N47 F31 has begun to exhibit significant hesitation during acceleration, resulting in a prolonged sense of sluggishness. Once at optimal velocity, it operates steadily and smoothly, devoid of any unpleasant sounds or other indications of malfunction.
During my recent trip, I observed that there is no hesitation during acceleration in 1st and 2nd gears, whereas the issue seems to begin from 3rd gear forward.
Initially, I suspected a Transfer Case malfunction; but, when recognizing that the problem mostly manifests from 3rd gear forward, I am now contemplating a gearbox issue.
I used ISTA+, which did not provide any fault codes for any component. However, when I scanned with Bimmerlink this morning, it documented the following codes:
Five faults in the central gateway module
101008: Non-resolvable ambiguous routing - SG absent from the SVT target table
101010: SIF error 100104: Hardware fault reason ZGW
100001: VcmResultSvtCheck - identification verification: Discrepancies between the actual SVT and the target SVT have been identified.
100204: Message monitoring: absence of system context signal 12
Two faults in motor electronics
27AC00: Internal DDE control unit (cyclical authentication): Program status verification failed
27AB00: Internal DDE control unit (cyclical authentication): data record verification failed 1C
Two faults in integrated chassis management
48276E: Autosar - StandardCore - Non-Volatile Memory - Integrity compromised 482656: Slip angle estimate - internal deterioration attributed to SBS
Does anybody possess insights or experiences about similar hesitation concerns, and if so, how were they resolved?
I own the ZF repair kit for the transmission and the appropriate fluid for the transfer case, which should address the issue; nevertheless, I anticipate that this may be too optimistic.
I appreciate your time in advance for reading this.
