DrJJC - to be honest, as a former DS owner who was suffered from this B-pillar issue for months, I truly don't think JLR knows how to completely fix this issue. The evidence is that they keep updating the bulletin document with added fixes, and more model years and VIN ranges are now involved.The other threads on the B Pillar have reached dead ends, so I thought I would throw up a hail mary and hope a good response is found.
I have had my DS in six times resulting in soft fixes, detailed body shop weld fix, spray foam in the pillar area, and finally a LR tech visit to my dealership. The sound from the B Pillar is still present in my left ear over bumps and then sometimes gets its rythem going in a constant manner on smooth roads.
The LR tech concluded that the sound is within acceptable limits.
Had anyone had this corrected to satisfaction? If so, do you know what fixed it?
I love everything else about this truck, but for the money spent on such a premium vehicle, I can't accept the sound as "acceptable".
Thanks for any help!
Since you have already talked to JLR without a resolution, I personally think your best option is to check your state law regarding lemon law protection.
I was one of the DS owners who "loved" DS just like you do, unfortunately piles of issues and frustrations ultimately prevented me from "loving" it.
