DIAG Test Codes on dash display

[AW8]

Sorry to undermine all your timely effort but as far as I can ascertain the DIAG data in Test NR.14 only relate to emissions related codes assocaited with the SES light.

DIAG 1 C7 81000 : The thing to do is to ignore the 81 as this i believe the first numbers relate merely to cycle references as to when the car tested itself - IMHO here there are no faults here- the last 2 numbers are 00


DIAG 2 BD 90038 : Using the PDF on my link and cross referencing M62 engine data Hex code 38 relates to a cylinder 7 misfire. This is likely to be a one off ( as the code is not repeated) but may point towards other things. If car running fine and No SES light on then dont even worry about it- just bear in mind..........if it keeps throwing the code the SES light may activate then yu can run another test on NR.14


Sorry but the other codes mean nothing to me and I am assuming they relate to BMW systems in workshops & not Test NR14 data. I dont have info to be able to give any conclusive interpretation of this data.

TEST NO. 14
This function shows the content of the fault memory in a hexadecimal code.

At least we agree on that one: it is hexadecimal

But I don't agree on that one :

the DIAG data in Test NR.14 only relate to emissions related codes assocaited with the SES light.

It would be more than a coincidence of having 2 fault codes in TEST NR. 14 and two "INSTRUMENT" fault in the diagnosis report starting with the same hexadecimal code:

DIAG 1 C7 81000 : INSTRUMENT - C7 Tank Sensor 1 (fuel-pump side)
DIAG 2 BD 90038 : INSTRUMENT - BD Electronic braking-force distribution - Instrument cluster (IKE High) kom

I interpret the "IKE High" above as oposite to "Base" Instrument Cluster. I do have the high one with 20 digit readout
