Last Tuesday, I acquired a 2015 7 series vehicle and transported it from Lancashire to Devon.
It was not until I was almost home that I saw the clock was showing zero, despite having already set it and the date.
Suspecting a possible incorrect setup, I proceeded to reset it.
Furthermore, the clock automatically resets itself upon the deactivation of the ignition.
After doing an investigation into the potential reasons, I discovered a common underlying factor that strongly suggests the primary battery as the probable culprit for the problem.
After conversing with the auto dealer from whom I bought the vehicle, I made arrangements for a technician from the AA to inspect the battery today.
Prior to doing a diagnostic check, the first discovery was that the positive connection was not securely fastened to the post.
After tightening it, he performed a Diagnostic check that revealed many issues in the battery, indicating the need for replacement.
He installed a brand new battery that was identical to the previous one and reprogrammed it using the On-Board Diagnostics (OBD) system.
All functions operated correctly, thereby resulting in a state of contentment and satisfaction.
However, when I returned to the vehicle shortly thereafter, I discovered that the clock had once again reset to zero and the Air Fragrance attachment had also been deactivated, despite my previous setting of level three.
All other features, such as seat and radio memory, were functioning well.
I have made many attempts to reset the clock, nevertheless the outcome remains same.
I am feeling disheartened and considering the possibility of returning the automobile, given that I have had it for less than a week.
Prior to proceeding, I kindly need input from members who possess extensive expertise to identify any other factors that may be contributing to the problem and provide potential solutions for its resolution.
We appreciate your patience.
