Took car on a 30 min drive, and when I got out I saw some white frothy liquid dripping verrrry slowly from a small metal box just in front of the spare tire well. Checked my SLS fluid reservoir and it is an inch or so low. If leaking from this location, any ideas what it is?

My ride is compliant - not to firm or soft. I'm thinking of just refilling the reservoir... the MB dealer identified this back in September, and if its only an inch low, must be a small leak. Would anything make it leak faster (e.g. heavy load)?

You guys are amazing. I don't DIY, but the knowledge I get here makes me an educated customer at my favorite repair shops. Thanks!
