I Have a 2007 SLK 350 and have an issue with the bottom temp/speed instrument gauge. I noticed a small pink squiggly line forming in the gauge. It started out to be about 1/4 inch and has now grown to about 1 inch in length. It looks like a worm track. Sounds bizarre. Any idea on what caused it or how to fix it?

Do a search in this forum on "pink shrimp".
Usually rlated to very cold temperature having an effect on the LCD pixels, sometimes, these will "self-heal" when the ambient temperature rises, e.g., going towards summer.
