This reminded me of a OP a few months back who changed cam adjusters , A6 V-10 engine in the car, and reversed the intake and exhaust adjusters on the drivers side. With the forums help, the OP needed to disassemble once again and switch them back. The OP's last post was that he dropped a small torques bolt down the head opening (below the adjusters) and into the timing cover / chain area ; in the back side of the engine. Could this be that engine?

Probably not as all the cam adjusters appear to have the same staining on them, but....... timing gear bolts (17:19) don't just shear off unless something stops the gear rotation. Which came first, the cylinder event which may cause the timing bolt shear OR a event with the timing gear which then caused the cylinder "event". It appears that only one cylinder was involved, if the timing gear sheared first, wouldn't there be more valves bent and cylinders involved as this engine clearly ran for a few revolutions / minutes??

Those Lamborghini V10’s had a LOT of problems, the parts prices are insane and an exchange unit from Audi UK is £25000… mind you that is a lot less than the £32000 for a Q8 e-tron battery
