All vw cars need to have the water system bled after filling with antifreeze,just undo the top heater hose clip to vent any trapped air in system......wear rubber gloves,its hot.

Is your car overheating ? Might not be related at all. Run your Passat until it reaches operating temperature and check to see if the fans behind your radiator turn on. The temperature sensor might be bad, when you replaced the O ring, did you also replace the sensor ?
1. Disconnect battery 2. Drain radiator 3. remove any plastic and or fan shroud 4. remove electronic fans if equipped 5. remove upper and lower radiator hoses 6. remove any heater return hoses (if routed to radiator on your vehicle) as well as any transmission, oil, or power steering cooler lines that may run to radiator (if so equipped) 6. remove radiator from core support (there should be anywhere from 2-4 bolts that hole it in or a clamp type mounting system) 7.installation of new unit is reverse of removal
WHEN CAR STARTING OVERHEATING MAKE SURE COOLANT LEVEL DIDNT GET TOO LOW. IF NOT I WOULD REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP IF OVERHEATING WHILE SITTING IDLING COOLING FAN NOT COMING ON.CHECK COOLING FAN FUSE AND RELAY IF ALL IS GOOD.CHECK COOLING BY HOTWIRING IT.IF RUNS YOU HAVE A BAD COOLANT TEMPERATURE SENSOR OR FAULT IN WIRE CIRCUIT.IF FAN DONT RUN WHEN HOTWIRED REPLACE FAN MOTOR.IF CAR STILL KEEP OVERHEATING CHECK ENGINE OIL LOOKS LIKE MILK BLOWN HEAD GASKET.IF OIL LOOKS OKAY YOU NEED RADIATOR AND ENGINE FLUSHED OUT.
I bet your car sounds like a diesel without the gas savings benefits. Your only solution is to replace the cam tensioner! Call VOA to complain about the manufacture defect.
faulty temperature sensor locate it going into the block and replace its located on the block itself usually drivers side or in the front has 1 wire coming out from it ...as far as overheating is concerned does the fan relay kick in and possibly you need the thermostat changed or is there enough radiator coolant in the radiator .
your fan rely is stuck...there are two of them and need replacement. I believe they are in the fuse box. You can tell which is bad by swapping them. Good luck
did the electric fan on the radiator start up? if this dont start up, it can get the engine overheated , specily if the car run in hot weather , an when the car stay on idle . The other problem is the engine head , the head gasket can blow and you get the compresion presure in the water chanal .Try to se of the oil on engine is gray? If gray you must change head gasket.
Hoope this can help you
