Has the car been serviced recently?
If not I would suggest getting it done.Not sure if you have diesel or petrol, but oil can thicken causing more load on the motor and airfilters get blocked and can cause a rich fuel mixture.

If petrol you can take out the plugs to check if they are a light brown colour, if very dark or black you need to check and adjust carb/injection settings/filter.Need to know what engine it is really.

Try replacing the sensor. They are not usually very expensive.
When the engine is COLD! Remove the wire to the sensor and unscrew it. A deep socket will be easiest. The hole will only leak a small amount of oil. Wipe the excess oil out of the hole and fit the new sensor. Turn it until it is tight but DON'T force it. Reconnect the wire and clean away any spilt oil.

The door lock solenoid for the passenger side is possibly defective, and that is what caused the fuse to blow in the first place. If you apply voltage to the solenoid and it works, then the driver transistor or wiring would be the next place to check. Hope this helps.

Check the coolant sensors. One sensor, when coolant is overheated, cuts the ac off, this sensor may be stuck electrically open, only two wires going to it. Other sensor has four wires, two for temp gage and two for engine management.

It is very possible the culprit is the radiator cap.

Try cleaning the throttle valve and the idle speed control valve. Use CRC brand spray throttle valve cleaner, about half the car will do it. Spray it into the engine intake while it running hold the idle up or it will stall out. After you have done this the idle problems should improve.

Do an exhaust pipe check on the car. It will tell you if the air is flowing through the cat and the muffler. If they are the fuel can't be pulled into the cylinder to fire the engine. Not sure the computer would keep it from starting as I am not a VW guy. As a quick check put your hand over the end of the exhaust and see if the pressure is strong or weak coming out. put gloves on so you don't get burnt from the exhaust. If it don't start at all currently remove the o2 sensor ahead of the cat and see if it starts, it will run rough but should start. Hope this helps.
