Replying to: jerry94 (Jul 04, 2008 2:21 pm) I have a 2002 TB with the inline 6 and I have the same knocking noise -usually 3 knocks- in the dash in front of the steering column. It happens at start up or within the first 3 minutes of driving. I also have a problem with the healights turning off while driving and don't know if these are related.
#46 of 46 Loud Knocking Noise on Start-up 2008 TB by tkelly1108 Nov 18, 2008 (11:25 am)
I have a 2008 TB that I bought in July of this year with only 10,714 miles on it. It has developed a loud popping/knocking noise mostly upon start-up but it has happend when in reverse and also in drive. I have had to the dealership 2 times, once they said that it was the drive shaft and the second time they said it could possibly be the AC clutch. They said that they could not duplicate the noise. Does anybody have any ideas of where to go now.
