2005 X5 4.4 Sport going haywire with codes and rear diff posi binding??

[HansBeamers]

Hello Xoutposters!

I recently hooked up a Zurich ZR-18 scanner to my 2005 x5 during our isolation time in 2020, and got a barrage of codes. I have one recurring symptom which I thought I fixed, a wet carpet on the drivers side even after checking pano roof drain tubes and cleaning/shortening them to operate properly. Any ideas on not so obvious leak sources?

I also have a new symptom, the rear axle seems to bind the wheel(s) upon turning sharply in a circle, its definately in RWD mode, and the 4x4 light is on, I'm assuming those two are related!

Anyways, here are the codes I got:

DME OEM enhanced code
1) 2E95 - Generator, DME OEM enhanced code (alternator seems to be charging fine)
2) 2E97 - Generator
3) 2F45 - Interface EWS - DME, (OEM enhanced code)

BMW OEM Enhanced EGS- Transmission Control
4) 4F7A- Message from LDM is wrong (Enhanced Transmission EGS control code)
5) 51B0 - Message (Brake-Light-Switch) From DSC is not Plausible
6) 4E87 - Magnetic- Valve 4 (Shiftlock)
7) 4FB2 - Gearbox internal error (watchdog)

ABS
8)5DD0 - UZ Error: Over voltage
9)5F3A - Clutch Gearbox-ECU: Clutch Is Open - Rear Wheel Drive!
10) 5EB0 - Steering Angle Sensor: Internal Error: Signal Invalid
11) 5F5B - CAN Message/Instrument cluster- Error: Instr2, ID 0x613: Km_Stand Sending Failure Identification

I am guessing here that one sensor could cause a bunch of these codes? Or something wet under the carpet causing some of this too? And others may have been caused from a low battery while ignition was on but not running?

Any assistance into this from you guys would be greatly appreciated!

Cheers,

Sorry to hear about all the fun, especially when you thought you were taking time to fix stuff, I know how disappointing that can be.

On the roof drains I really have no idea, though there is a ton of info on the site.

In regard to everything else I'm wondering if you may have a weak battery. My thought, these cars go hay-wire when the battery is low, I wondered if maybe the doors were left open for an extended time when you did your trouble shooting which may have exasperated an already weak battery? One thought, throw a charger on it for a bit and retest before you jump in to anything more major.

Good luck and keep us posted

Regarding the wet carpet...
under the car there are tubes on the left and right side of the transmission tunnel about 10mm diameter. Blow some compressed air back up those tubes and watch for a gush of water coming back out of the wet side when you let off the air.

I'll try that, maybe their easily/quickly clogged or or I blew them out the wrong way, but more testing and clearing them I will try. Thanks for the reply!

I had a bad battery recently and changed it, so maybe that's all it was. I changed my transfer case and rear diff oil last week, and she's still up on stands. Gonna fix/do regular maintenance on a few more things on her, then take her for a test drive soon, and see if the same codes re-appear or not.

Cheers
