1996 C220 Central locking
 

Hi , Plz help

1996 MB C220 Elegance Automatic

Sometimes the LED's in the rearview mirror and driver's door both flickers when I lock or unlock the car. It doesn't always happen , only now and then. I find that when I lock and unlock the car with the driver's door open in this case, the problem goes away for sometime. Is this a problem code of some sort ?

Thank you
Pieter.
