Hello, I have had my mavic air for about 13 months, I have started getting a message saying the processor chip is critically overheated.
When I first turn it all on it is fine and if I just take off I can fly, but as soon as I land I get the message, even if I power it up and then power off, when I power it up a second time I get the message, then if I totally turn the drone or the controller off, I get a message saying main controller error, and when I click the error it tells me there is a barometer error, is this common, is this repairable?

I assume that this will cost money?

Yeah your drones faulty, if your lucky it's just your fan that needs replacing, if your unlucky it's your main-board. While it's not impossible for other things to be faulty it's unlikely, it's more likely that your fan is faulty so your main-board is over heating, this is giving you the barometer and main controller data errors because your drone can't take the heat without cooling. If your drone was in warranty you could return it to DJI for a fix, if not you can try replacing the fan, this is pretty cheap and easy to do if you know what your doing. Like i said hopefully your lucky and it's only your fan that's the problem.
