I have a 2013 NMS Passat TDI SEL with keyless entry. It has recently started to intermittently fail to unlock the door with a touch of the driver side door handle. Locking all the door with the a touch of handle on driver side is working fine , except the driver side door is not locking at all . I can not lock the door with the key inserted to the lock either, after i removed the plastic cover from the door handle and inserted the key . To lock/unlock all the door from passenger side with the touch of the door handle working fine , except the driver side door is not locking at all . I got a clicking noise when im driving my car and the car got around 10-15 mph , sounds like its trying to lock all the door.
My guess is
nothing wrong with my kessy ( keyless entry) , or my remote ,( just in case i replaced the battery , and checked the voltage) ... it should be the driver side door lock latch itself , Door Lock Actuator
Ordered the parts few days ago to replace the latch , will update this post as soon as i got the the parts and replaced them .
