I'll give it another go as it seems like someone (an admin?) deleted my previous thread. I'll try to rephrase so it won't be mistaken for a salesad. =p
I'm wondering if there's a way to check whether the sensors still funtion or not? Do VX (or in my case, Opel) have a reader of some sort that can check? I don't have the system in my car, so that's not an option.
