Hello I have a problem with the keyless system when opening the doors, especially the driver’s door.If you drive with your hand into the door handle, the lock should open, but only rarely works.Everything with a cleaning cloth cleans up only partially.At the front door try it doesn’t always work.With the back doors it always works.The lock works with the button on the doors always. In the Volvo workshop they didn’t know exactly what was missing.They had read out with the OBD once and the system reset.Then it worked one day, then everything was the same again. Can this come from the scatter salt or the cold themperature. Would be grateful for any help. mfg
