S-Line door sill badging

[Swoot]

Hi all
My Sept 2010 A4 S-Line door sills at the front have discoloration/bubbling, or what could be moisture under the s-line badging plate. Has anyone had this before, or know a fix without replacing? Just looks a bit unsightly to me, not that anyone else would notice .......
Cheers

I'm not sure exactly where the discolouration is, but it sound as of it may be a warranty issue.

Not sure warranty will cover this on a 2010 car, will it?

Yep, same on mine - seems to be the same problem that effects the chrome trim around the windows.
Try some WD40 on a rag then wipe over it, doesn't fix it but it makes it bearable.
