Suggestion
IMHO, I would only fill the crack with new sealant, to keep moisture and water away, I seriously doubt that the frame/body is damaged by the impact, but to be sure you may want to meassure it to see if you find any discrepancies.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

To work on the exhaust, I have removed the rear bumper cover and bumper. Yesterday I noticed a sort of crack in the glue kind of stuff on the chassis, see picture below. On the left side of the car (where this picture is taken) it runs quite a way forward. Also around the rear part. On the right side It is only visible around the bumper post, not running forward along the main chassis beam. I have taken quite a bit of the car apart over the last year, with a lot of carpeting, panels, heat shields and liners removed and I have not seen this in other places. A few questions on this; 1. What is this glue kind of stuff called? 2. What would be the cause of these cracks? 3. Are they structural or only cosmetic? 4. Any advice on a fix?

POST 2Original post

Hello Marc, is the white round part on the right part of the picture, the bumper strut? If so, the glued section (cracked), perhaps was caused by a light impact on the bumper causing the dried glue to crack..?

POST 3 / ORIGINAL POSTEROriginal post

Yes, that is the bumper strut indeed. The car has taken a hit sometime in its life and this is most noticeable in the right rear. The longest crack happens to be on the left... Any advice on this?
