These comfort access door handles are great when they all work as intended but are a major weakness in the d3.
I have replaced all of mine during my ownership and its something I would recommend you do as faulty units have a tendency to keep the car awake when it should be sleeping.
I have had to replace the car battery twice because the door handles had the battery discharged to the point where it no longer performed well.
Since getting on top of the door handles I can now leave the car for many weeks at a time without any problems with the battery being flat.
8 weeks has been the longest so far without use and it fired up straight away with the battery at 100% on mmi and no faults in battery management module
