I have had a problem with my steering wheel for some time. After 10-15 minutes of play, it starts humming like in the video. All I have to do is unplug it and plug it in again, so I can play for hours and nothing happens. The steering wheel operates normally during this humming
I would also say that it's the fan. I also had that problem with mine 1 year after use.
If you give it some "gentle" slaps sometimes it passes away the noise
Your better option IMO is to substitute it by a Noctua fan. This is a very common mod done to this wheels.
I have the feeling that if you send it to warranty, sooner or later will happen again.
Internal fan.
What firmware version are you on?
TM released a new driver also.
I was not even aware until last evening.
It is a 2020 release.
Make sure you have it installed.
I installed a new firmware two days ago the problem remained.
I got a message today "We like to inform you that a RMA procedure has been started for your unit."
I will send steering wheels to them. If the problem persists then the fan will change.
thanks for the help
