98 540i .so my car has decided to slowly kill itself. the sunroof has broken, the cats went. my check brake message came on and my remote key stopped working, all on the same day. everything but the sunroof and key are fixed. parts are on order for sunroof. so my question is, how do you test the remote. i have tried to reprogram it via the bentley manual, replaced the battery, the light comes on, and all the keyless functions on the car itself work, just no remote response, can the transmitter be replaced by itself, if so, anyone know of where to get them other than the stealer?
