@chillout1983: Extrapolating Uwe's numbers and if the date of first-record for the battery regulator can be believed, the fault was first logged on 2015.07.02 and since then it has re-occurred on 62 subsequent ignition cycles (let's ignore the possibility for multiple records within a single ignition cycle).
On a very rough calculation this means that the 62 occurrences happened over about 2,100 days - so the probability of occurrence is approximately once in every month (likelihood of happening on any day=3%)
So , your observation ain't no surprise!! Maybe clear the and keep a watch on re-occurrence-perhaps?
