Hi there,

Checking if anyone might know what this strange error symbol is that popped up on my dash. I can't seem to upload a pic (upload gets stuck at 90%). So here's a link to imgur where I uploaded it: https://imgur.com/a/yfWP0mM

Any advice would be helpful. My local mechanic told me to take it to a Benz dealership. I took it there and they said it was most likely a sensor but they would need to keep my car for a few days to a week (and probably charge me 1000s) to find it and replace it.

I'd like to either replace it myself or at least go back to the dealership with a reasonable idea of what's wrong and how long/$ it would take to fix.

my car is an 2011 e 220 diesel, convertible/cabrio w212

Thanks for any thoughts/ideas/advice
