I own a BMW X5 that repeatedly fails to start. I have had the vehicle for almost a year and first saw it malfunctioning during the previous winter months.
I needed to purchase a battery pack to facilitate jump-starting it. Ultimately, four days later, I presented it to a technician, and it did not replicate the issues I had at home. The battery was examined and deemed functional, and it was suggested that I would want a key fob. I acquired a key fob, which was not the issue.
During this whole episode, I saw notifications such as "battery discharged" and "tire pressure," however remarkably, a few days later, the vehicle started without any complications, and I did not need to jump-start it. Seven months have elapsed since that time.
Last week, I encountered the same situation. Had to jump-start the vehicle after it remained inoperative for almost three days. The vehicle failed to retain charge for 30 minutes after shutdown.
Additionally, I notice a clicking sound from my left headlight and hear clicking emanating from the dashboard after jump-starting the vehicle. The engine light illuminated, indicating a "Control Module Communication Bus 'G' Off" error.
Two days later, the vehicle is functioning consistently, and the engine light is out; the only question remains: when will it fail again?
Can somebody provide me with some answers?
The car's battery remains the original, as shown by the labels. It is a vehicle from the year 2014. Should I get a new battery? I own two.
Thank you.
