At the end of your upper radiator hose, bolted to the engine block.

There are known problems with this vehicle's heater core not getting enough coolant flowing through it to blow hot air.
1) Even if the coolant looks good, there are problems with the heater core plugging up. One solution is to use a heavy duty cleaner (CLR pipe cleaner) to back flush the heater core. To know if the heater core is plugged up, disconnect the 2 heater hoses at the heater core and somehow connect a hose to one end of the core. Try to flow water through, it doesn't have to be high pressure, and there should be a steady stream. If not, try to get the cleaner directly into the heater core and let it soak. Then back flush it and a lot of scale should be seen coming out.

2) The other problem is that since the heater core is the highest point in the cooling system air tends to get trapped in it. This should only happen if the coolant goes low or someone has opened the system to service it. There are a number of ways to bleed the system (vacuum bleed, pressure bleed). One of the hoses should have a small hole in it for bleeding air, pull that hose back just enough so the hole allows coolant to flow out of it. Then accelerate the engine and get a good flow coming out, when no more air bubbles are present, there should be good heat.

3)I've heard of bad water pumps with low flow causing issues as well as an aux. water pump not fuctioning correctly leading to poor heat output from the heater core. Someone should confirm this as I cannot get much information on the aux water pump(electronic pump by the alternator that is supposed to run after the car is shut off).

Hope this helps.

Sometimes sensors can just be dirty, try wiping them with a clean soft rag.

The only way a lot of bulbs can burn out at once is overvoltage. Check your charging voltage with the car running, using a multimeter. Should be 13.8 volts; with the car off, about 12.6.

I am surprised it would even run with that much overfill. Drain the excess oil to the correct level. If excessive blue smoke is present, internal damage has occurred, if not its probably OK.

Its probably not really worth repairing such an old system.
I would replace it with something more modern with better sound and control.
CD s are kinda out these days when most of your music and nav are on your smart phone .
However, you could remove cd player, remove covers and using cotton buds and solvent, gently clean the pickups for the laser.
Its probably full of crud.
Good luck

That is your problem for purchasing a VW.
Better get a Tow truck to take it to a good VW mechanic if you can find one

have the fault codes read and look for a problem EVAP system not venting the tank ( opening the gas cap to put in fuel is allowing the tank to vent until the next time)
never on fuel lights as they are only an indication and can be off
