Hi all i little help please this seems to be a common problem, my Audi 80 tdi will not rev past 3000 rpm under load, I have read other people with same problem but am still not sure. One answer I am interested in is that there is a thin plastic pipe running from the a round metal housing on the top of the turbo this pipe is loose and in fact it's that loose it you can pull it out without any effort, is this right ?? Sorry I am not very technically minded and I live miles from anybody in the middle of nowhere. Thanks in anticipation of your help. Mike
