My vw golf is buzzing when car door opens and

Yes, it's just the car anticipating it might be started . The system primes the fuel system before you turn the key receiving the signal from your door lock mechanism so it would always start at the first try. The sound comes from the bottom right near the fuel tank. All VW's do this.

you might have hit hard to close the door. open door pad n try to open the gate

Hi,the chime is triggered by the ignition and door switch a easy way to test the ignition is if ignition is on and radio on and key is turned of and key is removed from ignition the radio must go of by it self if not ignition is faulty or have dirt inside so clean out with some cleaning spray.if problem is in door the interior lights will not work like it must with opening and closing of door.hope this helps.Conraad

the door lock mechanism inside the door is stiff and if you remove the door panel and give it a good squirt with engine oil from a oil, can it may ease it off and it will start working

stick key in driver door lock and unlock it. If that works, now see if the remote will unlock the door or doors..i remember reading in an owners manual once where you can program which doors open and close by they way you press and hold down the two main buttons, also after a battery change in the remote, i think, but not sure, i did this on a blazar i once owned... the owners manual said, that you had to be within 20 feet and press and hold down both buttons till it makes the arming sound.... Can i get some feedback cause im curious..thanks.

try this first (cheapest remedy first) open the sunroof fully take key out of ignition shut all doors then put the key in drivers door and hold key over 30 secs to unlock car(windows will go down)then wait 30 secs.then put key back in drivers door and hold key over 30 secs to lock car,windows will go up and the sunroof will close.if the sunroof does not shut properly then we start with motor park switch.....

check door switches remove 1 at a time and unplug it once you find the bad switch lights will go out
un plug 1 at a time

Check the recall from the manufacture

actuators working on all four

locking module could be out of sequence after the one door repaired

drop the vw back into the place where the door lock was replaced
get them to explain

there will be a screw behind the rubber this holds the handle in., if the door has not been used much, greaseing the mechanism may solve this
