From the day I took delivery of my Mk7 Golf 2Ltr GT TDI 5 Months ago I noticed a knocking or rattling noise comming from the rear end, I retuned to the dealer and he said it is the rear shock absorbers, all MK 7 GT's are the same, he car'nt do anything about it untill V.W.come up with a modification or replacement shocker ! V.W.UK Customer services said they are aware of this problem however V.W. Germany do not acknowledge there is a problem but they (VW UK ) will continue to push for some action, in the meantime I will have to put up with it, as more people complain is is more likely VW Wolfsberg will do somthing about it. The noise is more noticeable around 30 / 40 MPH and the sound could be decribed as the same as a loose top mounting.
