Technical Service
SUBJECT
S63 - Diagnosis for FC 2AAE
MODEL
E70 (X5 M) with S63 engine
E71 (X6 M) with S63 engine
SITUATION
Fault code 2AAE (Fuel pump over-temperature; currently not present) is stored in the DME. The fault does not cause the Service Engine Soon
illumination or there are no any drivability complaints.
INFORMATION
Fault code 2AAE (if stored alone, without any other faults related to the low fuel pressure system) is caused by DME diagnostic sensitivity, and
should not be considered an indication of low-pressure system malfunction.
Do not replace the low-pressure system components (e.g., EKP module, pressure sensor, electric fuel pump or filter) in order to address FC 2AAE.
The low fuel pressure system should be diagnosed (using the appropriate ISTA D test module) only if fault code 2AAE (Fuel pump
over-temperature) is stored together with other low-pressure faults (e.g., 2A28 - "Fuel low pressure system" or EKP control-related faults
6516/6517/6296).
