Mine is a miracle of modern engineering...the whole danm car is networked/computer controlled. Even the lights.....Everything. What a night mare to trouble shoot electrical gremlins, which can be often..
I think the higest number of networked modules so far is 19 that i have counted during a code scan. Soon body shops will need to provide proof of scans before and after the repair. One local body shop has me scan for them.
If i have to do 2x,it looks like they will cover the fancy upgrade im considering.
