Hi guys, i am having a very not fun issue. The car is throwing warnings that my mirror indicators are not working (they are working, everything is working), sometimes right, sometimes left, sometimes both. It goes away by itself, comes back mostly when it rains a lot or when the car sits in a temp controlled garage... !
I also have an issue which might be related, might not, imma write it anyways. I get "front left malfunction" airbag error every few months, i take it to the shop, they say its moisture on the sockets and send me home. This time they said they dont know why, and next time they wanna check all the drains etc since everything is dry around the socket, but the socket itself.

I would buy a weeks worth of beer for anyone who has had similar issues with a mercedes, or a c220d 2015 w205. I know its near impossible to trouble shoot sth like this from distance and these descriptions but maybe someone has had a similar issue! Thanks for the help guys.
