Car is 2002 A4 B6 2.0 Sedan. Problem is when i open trunk, there's no light in trunk. Also no open trunk warning on DIS. Open doors and hood is shown on DIS. Connected VCDS and no open trunk lid or latch activity is shown in measuring blocks but everything works. Both microswitches works and signal comes directly to CCM, also no broken wires. Replaced CCM and recoded - still nothing. Interior lights works as should but there is one interesting anomaly. When i open door to get interior lights turn on and open trunk soon after, interior lights immediately turns off (was also so before CCM replacement). Now i'm thinking maybe it's CECM. Does any interior and trunk lights wires go through CECM?

Thanks!
