I've seen this issue posted way back about 04's but I don't think anyone ever got a resolution.<p>When I go over speed bumps, large road undulations or any other item that requires a good deal of suspension articulation, I am rewarded by a large "clunk" sound immediately AFTER all four wheels have gone over the bump. (To reproduce this consistantly, one can go over a speedbump at a 45 degree angle at about 10mph in Advanced mode)<p>I've complained twice about this issue to the dealer with no avail.<br>Anyone else have a similar issue/resolution?<p>Please no 4C bashing;just the facts.

Since you didn't mention it, I'm going to assume that you didn't get this TNN done: <p>TNN76-04-2004-02-09<br>NO: 76-04 CHASSIS: 285 0349395 -384 0315516 <br>SUBJECT: Noise from rear shocks R - Cars<br>DESCRIPTION:<br>A noise from the rear shock absorbers may occur when driving over small road disturbances. <p>SERVICE:<br>The SUM (Suspension Module) should be loaded with the new SW Quality Upgrade, FID 950(P/N 8691393). To check if FID 950 (P/N 8691393) has already been downloaded to a vehicle, the unique SW P/N 30669894 should be able to read out from the SUM via VADIS.<br>The SUM has to be calibrated after downloading this software. See VADIS for procedure:Vehicle Communication/ Group 7/ Suspension Module/ Calibrating the system.<p>NOTE! The Headlights need to be in the on position prior to calibration; If the headlights are not turned on during calibration they could be set out of position.

Re: Rear End Clunk (smolvar)

Unfortunately you will have to get rev 4 (5?). It WILL be softer but the odds are that the clunking will go away.<br>If you are still running Rev 2 Volvo will/can do nothing for you until you get the latest software

Re: Rear End Clunk (JRL)

i think going over speedbumps at 10mph in advanced is kind of asking for it <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/eek.gif" BORDER="0"> if you must go over them in advanced at least go slower because in my opinion it can damage/wear out things quicker because more of that bump is transfered to other parts of the car rather then the proper suspension components like the shocks. i think sport is the best for going over speedbumps. in comfort the car just bounces up and down too much. i think though the more you drive in advanced which to me is intended to be used only on the track or on extremely smooth road surfaces is going to cause more squeaks and rattles because of all that energy being transfered throughout the car.<p>i agree with the software update for the 4c though, if that doesnt fix it you probably have something else wrong. but you may not want to get the update if you like taking speedbumps at 10mph in advanced <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0">

Re: Rear End Clunk (sk11vengeance)

the way I see it, there's something loose and lodged in the cavity between the spare tire and the bumper.<p>it's not something inside the trunk, or a loose jack for that matter.
