Dimples in E90 hood (2008 328i wagon) from factory glue

Hi all - Today, I noticed some very evenly spaced dimples in my alpine white wagon on the hood. They look like perfectly spaced apart dent repairs, but because it's so uniform I didn't think that was it.

I thought maybe it was some screws underneath hitting the hood...THEN I searched around an saw on another forum that it was caused by the glue spots that hold the hood to the structure? Apparently others have had this issue as well.

Just wondering:1. Have you seen these hood dimples?
2. What did you do to fix them?
3. My car is out of warrantly (56k) - any chance for a goodwill fix?

I'd take pictures but they are so subtle you can barely tell. I think if you have them you'll be able to see them if you get right down to the hood.

Would love to hear your input!

I've never heard of this before. If it is a factory issue, I would think that you would have noticed it before.

I don't think that is something that the dealer would agree to fix - it sounds purely cosmetic. They'd probably want to charge you an arm and leg for it. All cosmetic work is gravy to them and they tend to overcharge.

I just got the car about a week ago, and didn't notice it until I was giving it a full detail the other day. I'm very sure the dimples are not related to hail, accident, etc. The dimples are in a straight line and spaced perfectly apart. Not only that, the previous owner took really good care of the car and didn't have any accidents/issues with the car. I'll see if I can take some pictures today or tomorrow.

I forgot to mention - the dimples are very very subtle. Something I can live with, BUT, if there is a diy repair why not right? The link below talks about cutting the glue points that will release the pressure pulling the sheet metal down - just want to hear more about this from other members.

FYI here's the link to where I found somebody else having this issue: www.bimmerfest.com/f...wthread.php?t=152854

"dimples on hood" reminded of that one mythbuster episode where they proved that if cars had dimples them instead of a smooth surface that there'd be less air resistance and improved efficiency.

Bump for you.
