Hi Tim, and welcome to the forum from Egg Harbor Township, New Jersey. I've been to cornwall and had some of those great pasties. FrankieI to have owned a Z3 wide body Titanium Silver 2000 for 9 years , given me a few headaches but definately worth it . I am now having trouble with my central locking drivers door not working on the fob but works on the key , also alarm sounds is this because of the door problem
Hope you resolve your issue.The loom if doom as mentioned is a great place to start few down the wires the often break inside near the loom retention clip.
