My only thought. I have had a couple problems with the magnetic keys in my cars. My wife key has gone bad twice but my key would work. It was the car she drives with her key. My key worked which I rarely used so we just replaced her key with a factory original from the dealership our problem was solved. I would suggest you swap the key you use and see if it makes a difference. If it does you will have some new info to give to the dealership.

This might seem a silly suggestion but have you checked the actual switch on the light? It can be set to always on, Always off or door triggered. The rocker switch is usually set to the middle position for the door setting. Most modern cars now fit the switch into the actual door latch built into the door panel. You would possibly need to strip the door card off to remove the whole unit just to get access to the switch.

It looks like it is hidden in the lock. See the WD40 image and the videos may help you. https://www.google.com/search?q=2013+VW+UP+dome+light+door+switch ..

If it 'cranks' it IS turning over. It is turning over, (cranking) but isn't 'firing' :>) You need to remove a fuel line near the engine firewall and verify the pump is working. You may have burned the pump out as they rely on the fuel for lubrication and cooling. Also check for codes with a scan tool. https://www.google.com/search?q=2000+vw+cabriolet+fuel+system+diagram&safe=off&rlz=1C1QJDB_enCA643CA644&sxsrf=ALeKk03DWp28xQEoml01rV2pInqNX75RDQ:1619470219577&source=lnms&tbm=isch&sa=X&ved=2ahUKEwiA06XZ5JzwAhVZWs0KHZVaBr0Q_AUoAXoECAEQAw&biw=1920&bih=937 ..

This can depend on the year of the vehicle, which engine is fitted and the fuel type. The Velociti is also know as the Mk1 Golf, (the later facelift version), and the Rabbit. A workshop manual for any of these will have that information. It is worth getting a manual if you are doing these types of bigger repairs.

Two choices: take it to an automotive electrician. tell him you have parasitic draw. Or you get an ammeter and put it on the battery. Then you pull one fuse at a time until the draw stops. That purely tells you the circuit is in on. Then you have to find the item.

Any check engine light? Does it run ok off idle/driving? Check for vacuum leaks like bad cracked loose hoses first.

Removed homophobic word and reworded question On the low right-hand side -- passenger side -- of the transmission you'll see the drain plug. On the front, upper left-hand corner you'll see the fill-check plug.

Does it run OK?

Are you sure it wasn't sparking prior to jumping?

Did you actually check the power supply to the pump or just assume there is no power because the fuse was ok? If there really is no power in the fuel pump circuit it might be a function of the immobiliser to cut the power until it is disarmed but if there is power, proved by the use of a test lamp, the pump is probably defective. In depth troubleshooting isn't practical without reference to a wiring diagram.
