Hi,
As you can see from the attached pics I'm getting two errors on my X3. They appear repeatedly after driving a very short distance.

Seeing this video make it look like a simple DIY fix- if it is just a sensor fault.
Can I just use a PC or Phone to diagnose the issue?

Questions-
1) Can i get a cheap diagnostic cable from Amazon like 'Enet Rj45 cable ethernet connector tools to OBD Interface Cable Coding F-series' to diagnose th issue?
2) Is that cable just for coding or also diagnostics?
3) Where do I get the software from to work with the cable.
4) is there something better for IOS or Android?
5) any suggestion for where to get parts from in the UK?

Thanks in advance.

if you want a super simple and cheap setup straight from your phone I recommend something like the veepeak obdcheck ble (https://amzn.to/3VPM0ZK) and using the car scanner pro (carscanner.info) app. It can read every module and if you want to dabble in coding/customizing it works with bimmercode as well.
I only lug out my computer and enet cable for maintenance that requires ISTA or VO coding.

BIMMERGEEKS PROTOOL, hands down with an OBDii adaptor. Best tool out there for the DIYer...

Hi,
When i was driving, it suddenly throws me 3 errors:
- Driving stabilisation. Drive moderately (accompanied by abs and 4x4 sign on my dashboard)
- Flat tyre monitor (rpa) failure
- Parking brake only partially available

I stopped and restarted the car, all problems gone, no fault.

Scanned faults via OBD interface and there is not much to see, these faulty codes doesn't seem to be present during the scan hence they disappear.
My service is due to brake fluid and thought this could be the cause of an warning that the brake system must be checked.

so what was the issiue? I have exact same warning lights. Emf or someother module? or just simpe sensor?

In my case it was the transfer box :-(
See- https://x3.xbimmers.com/forums/showthread.php?t=2035471
There's no low lubrication sensor in the transfer box, so if it's weeping then it will burn out when it gets too low. You need to pay for a diagnosis so you don't get down a blind alley.

how can transfer box cause abs and partial parking brake? Sounds weird to me

Also from what i have read transfer case is only on xdrive bmw and mine in rwd so i guess its not my problem?

The systems are linked- transfer box failure affects the car stability because it can't split the drive front and back. From memory it went rear wheel drive only. I had it diagnosed at an BMW independent specialist, but they wanted £££ to fix. Found someone on ebay who also ran a OBD diagnosis, and knew exactly that the issue was the transfer box. Did the swap for 25% the price. Since it's been swapped the error has gone, and everything is ok after 10,000 miles.

My advice is pay for the diagnosis, then make a decision.

Just pay for a diagnosis. I got the BMW computer tools and downloaded the codes, but without experience the codes don't mean much.

I am getting it diagnosed asap but obd scanner gave very weird code u0f2e01 dtc cannot be verified. Also today noticed that my rear brake lights turned on and off on its own when brake wasnt pressed.
