Hi, I will probably run into the same issue…. do you think I need to worry about this what I have just seen, when removed the lower cover for an oil change? (I live in EU where the roads are still salted for winter). So is this a rust I need to worry? This is the same pipe, just from the bottom. I have seen some parts from Ebay that may fit here: https://www.ebay.de/itm/NEW-MB-SLK-R....m46890.l49286
And this is still in production.
