hello folks,i have a 2002 tt [ary engine]and the air pump whistles on cold start up for about a minute, and then its fine,i removed it last week and replaced all the bolts as i was told this would reduce the noise but it didnt,im tempted to just disconnect it,has anybody any info on these pumps as im told they were just a phase vag went through and they dont do much for the emissions anyway,any advice would be really appreciated,
thanks greg.
