I've rebuilt my ver 1's twice now, the hall sensors still worked through the first rebuild. By the time they needed a second rebuild both HS were shot. Made contact with Fanatec, I'd have to look at my email to get his name but he supplied both sets free.
My CSP are way past warranty but like anything else if you talk respect to them they are usually help you out. It was about 6-8 months ago so I wouldn't know how there supply is holding out. Load cells I have gone through more then I can remember, some have lasted only hours, some 2 years or so.
