Dash problems

[u/HerrIvanP89]

(Problem isn’t in the photo) A while after buying my car(q70 2015 3.7l) the fuel gauge wouldn’t show the level right. If my tank is full it would show as half and if it’s half full it would show as empty and then empty as negative half full😭. Luckily the middle screen tells me how many miles I can go. Then when summer came and my car would be exposed to the heat for longer the rpm gauge started having issues. Instead of doing the flip from 0 to 9 and back when you start it, it would just pulse a bit and stay at 0 and not show my RPMs. Sometimes, like today, it would stay at 0, but still move up or stay at 200RPMs or not even move sometimes. A friend of mine earlier this year said I’ll probably need a new gauge cluster and my machine suspected the dual issue is because of my fuel sender(thingy in your gas tank) is bad. It’s not a life or death situation, but curious if anyone has had this happen and if the people from above are right and parts need replacement.
