How to fix the electrical problem of my 2004 A4 Audi Quattro

Asked by GuruVZP9Y Aug 05, 2018 at 01:27 PM about the 2004 Audi A4 3.0 quattro Cabriolet AWD

Question type: Maintenance & Repair

I am having a problem with my 2004 A4 Audi Quattro. At first it started off
with lights in my car's interior turning on and off randomly, but then my turn
signals and headlights did the same until it got to the point my car wouldn't
start two days later. I took it to a mechanic before it refused to start and they
said everything was fine except the body control module or pcm not
communicating with the powertrain bus. Something about a code 18107 and
18043 that relates to an ignition switch issue but I'm not fully sure. What do
you think is the problem and how would I go about solving this issue?
