Problems with the ABS/DSC system on BMW X5

Hello everyone, I have a problem with the ABS in my BMW X5. The ABS and DSC lights sometimes come on, but are often off for longer periods of time. When the lights are off, the ABS and all other systems work perfectly. However, I cannot read out any fault codes, neither when the lights are on nor when everything is working. Even with the Carley diagnostic tool I can't get any information about the ABS system, although on other models like Opel or VW it at least shows the presence of the ABS. Does anyone have any idea what this could be due to or how I can diagnose the problem? Many thanks in advance!

Start by checking the wheel speed sensors for dirt or damage, as they can cause intermittent ABS and DSC light issues. Clean them and ensure they are properly connected. If the problem persists, let me know for further guidance.

I did that a long time ago, that's not the reason, as I said according to carly there is not even ABS on the vehicle, can it not read it out at BMB?? as I said with other models it shows me abs that it is either ok or just error, not with the x5 e53

It's possible that the diagnostic tool you're using isn't fully compatible with your BMW X5's ABS system. Try using a BMW-specific diagnostic tool or software like INPA or ISTA, which are designed to communicate with BMW systems more effectively. If you still can't retrieve any codes, it might be worth checking the ABS module connections for any loose or corroded contacts. Let me know how it goes or if you have further questions!
