My 07 TB is currently at 110k miles. It has recently started to show some electrical issues and I am looking for guidance on what modules I might need to start checking into.
The first issue is when the front passenger door opens. The cabin lights turn on but immediately dim and turn off. All other doors cause the cabin lights to operate correctly.
The other issue is with the radio and it just surfaced this morning. When I parked at my office, I turned off the car, removed the key and opened the drivers door. The radio stayed on. I shut the door and when i reopened it the radio turned off. I have an aftermarket radio so I will start with the adapter for the BOSE system/door chime but from there, what should I look at? Edit: This is intermittent. Repeated a few times then functioned as normal with radio turning off immediately upon opening door. BTW...how does the car know the door is open? Is it a switch in the latch?
DDM and PDM? Do these have a history of wire insulation failures similar to the LCM?
TIA!
