Luggage compartment lid “manual” possible unlock?

Dear Phaeton fan community, although I have not been driving a Phaeton since 2014, but I miss “him” already very much… The 5er Touring is also awesome (have now 2 toddlers – that’s why…), but if you have driven the “Diva” once, unique… An acquaintance recently bought a used Phaeton from 2004, 4.2 l (8 cyl.) and has the following problem: His wife has her handbag in the trunk,. Rear flap closed and somehow the handle, in the lock or rear flaps Since then, the rear flap has been closed, with keys, pressing on the VW emblem, switch inside – nothing is happening anymore. There is a message in the display (somehow, trunk open) but the boot lid can no longer be opened. Question to the fan community: Is there a way to open the lid manually or is the only way out to pierce the lock to open the flap? What could be broken – someone knows a workshop that has the problem cost-effectively? Stig could fix, especially since the car is yes BJ 2004? Thank you in advance and all the time a good ride!
