The old mounting plate. sorry don't know if this is the correct name. But I did not use a bracket. I wanted to keep this original mo possible. But end up with abs, esp, tyre pressure even power steering went off so finally went to emergency mode. Problems with abs sensor I think? After reading this en reprogram it's still saying the same. Only now he said even that one wheel is turning wrong side. Hooked the PC again when driving to read the rotation of the 4 wheels but it was reading no problem
