Error memory: short circuit by mass

Dear screwdrivers and electricians, after the exchange of the transverse handlebar bushings, error memory was read out. It often happens “short circuit after mass”, especially at the rear flap lock which by the way no longer works when you press on the VW emblem. All other rear flap switches still work. At some point I have read here about a problematic wire harness. Could this be the cause? Where can I find this or what is the right chapter in EPAS? This was a mechanical problem, however, it is really quite “flimsy” built. Here is the protocol. When the memory was deleted the last time I can not say. May be that the errors have accumulated over several years. Thanks already for possible hints and greetings, Thomas 11 error codes found: 00668 – Onboard voltage terminal 30 002 – below limit – Sporadic 00576 – terminal 15 008 – unplausible signal – sporadic 01141 – switch for rear flap unlocking (E165) 007 – short circuit after mass – sporadic 00325 – button for rear window opening (E361) 007 – short circuit after mass – sporadic 00901 – rear-view lamps 009 – interruption/short circuit after mass 01331 – door control driver side (J386) 002 – lower limit – sporadic 01332 – door control passenger side (J387) 002 – lower limit – sporadic 01333 – door control guesses rear left (J388) 002 – lower limit below – Sporadic 01334 – door control unit rear right (J389) 002 – lower limit below – Sporadic 00318 – supply voltage for control unit for tailgate 002 – lower limit below – Sporadic 00896 – closing unit tailgate (F256) 008 – unplausible signal – Sporadic
