It's diesel. Diesel engines do not like cold, but that is normal. I am going to assume this engine has a start delay in cold weather to allow for Glow Plugs to warm up the cylinders before actually turning over the engine. I don't know about TDI's specifically, but I think a TDI Mech at your local Volkswagen dealer could confirm my assumption. They may call the parts something different, but the function will be the same. Sounds like normal operation for a diesel engine in cold weather...obviously, this would be why the engine always turns over immediately in warm weather...no need for the Glow Plugs to warm the cylinders. Best of luck resolving this problem.
more then likely the battery is going bad. in cold weather it takes a good (cca) cold cranking amps, battery to turn engine over. but in warm weather the engine is not as cold and therefore needs less cranking amps. thats why you hear clicking when trying to start car in cold. it is the solinoid clicking and not enough power for starter to turn it over.
Extreme cold weather is causing coolant to contract and fluid level is reading low level ... After starting with the engine warm the temp light should go off due to expansion of the coolant ... Solution: Add a small amount of coolant to compensate for cold weather contraction. Good luck!
SCAN IT FOR IDLE SPEED CONTROL PROBLEMS.BUT OTHER POSSIBLE CAUSES TO YOUR STALLING IS BAD PLUGS AND WIRES CLOGGED FUEL INJECTORS AND CLOGGED FUEL FILTER.IF ALL IS GOOD HAVE FUEL PUMP FUEL PRESSURE CHECKED IT SHOULD BE 41- 47 PSI.
Most likely if it is temperature related you may have a temperature sensor that is failing. The sensor may not be reacting properly to the actual temperature and causing the engine to run rich in warmer weather when a richer setting is not required.
You could have a sticking injector or sticking EGR valve or a faulty TPS switch, all can cause a rich condition and a poor running engine.
Is the service engine light on or come on at some point?
I would start by having the car scanned for trouble codes. You can have the scanned at no cost to you at your local Auto Zone or Advance Auto Parts. Write the codes down and respond back.
