These codes mean nothing to me & I believe they are not recognised generic OBDII codes, (they don't start with a P for powertrain). I am not daft and have not and would not reset anything!

I had my X5 diagnosed today by the dealer as I had a message "SELFLEVEL. SUSP INACT." continuously.
Prior giving my car for inspection, I ran a TEST NR.14 to see what error codes were present. I had two:
DIAG 1 C7 81000
DIAG 2 BD 90038
Now here is what the diagnostic report says:
Quote:
INSTRUMENT - C7 Tank Sensor 1 (fuel-pump side)
INSTRUMENT - BD Electronic braking-force distribution - Instrument cluster (IKE High) kom
LCM - 99 Number-plate light faulty - License-plate light B6300_00016
MRS4 - 0B Battery, positive terminal isolation 1 - -- - Currently not present - -- - -- - -- - Resistance too high - Fault frequency 1 - Battery safety terminal B6510_30008
LCM - 91 Turn indicator, rear right faulty - Turn indicator, rear right B6300_00008
LCM - 90 Turn indicator, rear left faulty - Turn indicator, rear left B6300_00007
LCM - 81 High beam, right, faulty - High beam headlight, right B6300_00004
LCM - 96 Reversing lamp, left, faulty - Reversing light, left B6300_00024
ECH - 01 Ride-level sensor, left - Height/loading sensor B3714_3901N
ECH - 09 Control-time fault "Lowering" - Lower control time B3714_E39REG09

Having that report in hand, I did extra search for "Tank Sensor 1" and found this:

Incorrect Fuel Gauge Reading
Model:
BMW E53 (X5) vehicles produced before August 17 th 2000.
Complaint:
After the tank has been filled the fuel gauge will either not read “full”, or the correct reading will only be shown once the ignition has been switched OFF and ON again. These faults will be stored in the Instrument Cluster:
- Fault Code 8 – Fuel tank sensor 1 (fuel –pump side) and/or
-Fault Code 9 – Fuel tank sensor 2 (without fuel pump)
These errors are caused by a non-conducting deposit being formed on the conductor surface of the fuel level sensor.
Remedy:
Using the DIS or MoDiC:
-Select diagnosis
-Select Function Selection/Complete Vehicle/Body/Displays and Information/Instrument Cluster.
-Select Test Plan
-Select 4 – Expert Mode/ Read Fault Memory to confirm fault codes 8 and/or 9 are set.
-Select 3 Service Functions/ 1 – Test Code
-Press ‘Test Code’ button to save test code.
-Print Diagnosis Report
-Remove and replace the right hand delivery unit and the left hand fuel level sensor. Refer to repair instructions 16 12 000 and 16 12 001.
-Also to ensure a correct installation of the left side sensor use the following procedure:
-Lubricate the small o-ring for the fuel transfer pipe to ensure the o-ring does not push out of position when the fuel transfer pipe is being installed.
-Lubricate the inside edge of the large o-ring seal, so that the fuel level sensor will slide easily into position.
-The fuel level sensor must be installed keeping the top flange square to the tank at all times. Rotate the sensor so that the lug is located above it’s recess, then push the sensor vertically down into position. It must NOT be installed at an angle.
-Using the DIS or MoDiC select 4 – Expert Mode/ Clear Fault Memory to clear the fault code memory.

As per the "SELFLEVEL. SUSP INACT." message, it is clearly because of the faulty ride-level sensor on the rear left. I assume the
BD 90038 code comes from there as the braking-force distribution might be linked to suspension.
I don't know what the
MRS4 Battery, positive termination error code means but I could figure out the positive cable (directly on battery) has several wires. 2 big red wires and 2 small black wires in one single isulation tube. These wires go along the trunk (left side) to the end of the trunk, just beneath the rear seats. I t just ends there... any help?
Finally, the other codes "
LCM" where raised some days ago when I did a full bulbs check/cleanup. It just remains in computer memory. "Big brother is watching you..."
