Sometimes the acceleration stops like this in the video and its annoying ... and it got much worse
Any idea that can help me fixing it at home?
I dont have warranty
I've heard that if you open them up and clean the dust out or maybe put a little wd40 on the potentiometers that can fix it, also make sure the wire in the back is in properly, don't quote me on any of this but it's worth a try.
You should call them or make a ticket on their website. They have replaced mice for me out of warranty. They are really good at backing up their products.
Similar thing is happening to me and I have already tried a second set of pedals. Last recommendation to me was to 'update the software' from Logitech, but don't know how I would do that or if it even applies when using with a PS3.
If you send it back make sure they have it in stock first and send it that day. I sent my whole wheel back to be replaced and it took over 3 months and the involvement of the BBB to get my wheel back.
If you have a look at my webpage you'll see a link to a guy who sells replacement pots for the pedals, I've used them and they work with no modification to the pedals required.
