Great news. Wife's A4 starting making a noise as well. Sounds like it comes from under the middle of the car. Sound similar? Was the heat shield repairable or did you have to replace cat? Thx!

1.8t or 2.8? 1.8t cats are connected to the turbo, one way in and out - ScratchRob13 2008-09-21 21:39:34 (61 views)

yes. here's a pic of an aftermarket one. both of the O2 sensors are connected to it. - JAFO 2008-09-21 09:31:19 (105 views)

could it be my throwout bearing on my clutch? - inwoo 2008-09-10 17:49:26 (52 views)

does it go away or change pitch if you press the clutch? - ScratchRob13 2008-09-10 19:57:11 (42 views)

nope. - inwoo 2008-09-10 20:08:05 (42 views)

no cam chain tensioner, in the head, search for it... see if the symptoms match - ScratchRob13 2008-09-10 19:56:43 (85 views)

checked it out and seems like it is my cam chain tensioner.any large damage if not replaced quickly? - inwoo 2008-09-10 23:17:38 (79 views)

well if that chain get too slack... yes - ScratchRob13 2008-09-11 11:52:50 (64 views)

it's not throwing any codes yet, but i'll get it looked at right away. - inwoo 2008-09-11 12:05:09 (52 views)

if it throws a code... then its too late, that keeps the two cams in sequence - ScratchRob13 2008-09-11 14:06:36 (54 views)
