If the lid now operates properly:

Check the luggage compartment lamp part number by VIN in ETKA
As a test:

Unplug the lamps and retest operation.
If operation is restored:

If the incorrect parts installed, replace with the correct parts for the vehicle.
If the issue is still present:

Check the MVB for the lid lock motor in the -J519-.
If not reading correctly:

Check wiring and replace the lock motor as needed.
If the MVB read correctly but the condition still exists:

Monitor MVB for the rear lid motor sensors in -J605-, if sensors reads implausible or doesn't match current
rear lid position, check wiring and connectors and repair as needed.
If all tests pass and a source is not found, suspect a rear lid lock.
