Jingle bells

[chrisneill]

Morning everyone. About a year ago I posted on this site a problem with my 2011 +2. The problem being that any bump my rear near side wheel went over I heard a sound that I can only describe as bells jingling. This problem has become progressively worse whereby the smallest undulation in the road will cause the noise. It is rather embarrassing driving down a street that is not perfectly smooth. I have had the car into a garage who have been unable to recreate the noise with the car on ramps. I had convinced myself that the problem was with the cat converter and something had broken up inside. But, at the weekend, I had a full load in the car - 6 people - with a near 6 foot teenager in one of the rearmost seats. No jingling whatsoever. This suggests that the problem is surely suspension related? Looking for some inspiration here as the noise is intolerable. Thanks very much
