These ECUs often only last about 7 or 8 years. This is a brand new OEM part bought from the local Maserati dealer (at an obscene markup). Turns out that I didn't need it, it was just bad TPMS sensors. Paid $365, will sell for $200. Part is 310225. Works on 2011 and later GTS. I already traded in the car so I have no need for this.
