Knocking/Tapping Noise
« on: 18 September 2008, 08:42 »
Hi all, over the past few weeks I've noticed a tapping/knocking sound that appears to be coming from over by the passenger air vent. It only ever lasts a few seconds a generally happens when I've got the fan on low and quite often when the car is stationery.

I was wondering if anyone else had experienced this or if anyone knows what it is?

Yeah I have that noise too - had it since new. Don't know what it is though, has never caused a problem for the car either...

Would be interested to find out what it is!

i get this very occasionally but just assumed it was something to do with the aircon "warming up" but i'd be interested to see if someone knows what it actually is

Its a very common thing with the VAG dual zone climate. On rare occasions it maens the pump or something is failing, but most of the time its a completely normal characteristic. It does it ALOT with mine.

A job lot of loose screws?!  :huh:  :grin:

Seriously, is it roughly about three knocks - more "plastic" rather than "metalic" sounding?  I get that too!  :rolleyes:

I think it is something to do with the air-con redirecting air through the different vents when the climate control is on auto
