I have some strange errors on my XJL 2010 X351 3,0D. Suddenly the display reports almost all possible errors that can exist in the car. ABS Suspension Gearbox ... and the speedometer goes to 0 and gearbox into some safety mode with only 3rd gear available. After a restart the symptoms can be gone for some time to reappear maybe 2 hours later. It sets almost all errors in the system and very hard to determine the cause. Anyone have some ideas what to do?

 

Low battery, weak alternator, loose electric connection come to mind...

 

Had the same problem with my Range Rover, dealer replaced the battery and the problem was solved.

 

Ok, my battery is not yet a year old. I will check all the ground points and all connections I can find and see what happens.
thanks

 

I forgot to mention, it was a 2018 MY Range Rover. That said, it could very well be the battery.

 

Interesting, I never had this problem before I switched the battery. I will measure the voltage while driving to see if i can verify anything. Thanks for the advice.
