Please clarify, Although the alternator light is on, can you start the car? Does it turn over, but not start? If it won't turn over, you 1st need to charge the battery and try to start it. If the light remains on, have your alternator checked, it probably isn't charging the battery. How old is the battery? If it doesn't charge up, it should also be tested to make sure it's ok. Let me know the answers to the above, and let me know what happens. good luck countrycurt0

as per vw, you need to check transmission oil level., not an easy thing to do. if transmission oil level ok (no dipstick on these by the way). it is a mecahnical fault.

That engine is an ALH engine code and 1.9l TDI non pump deuse...The thermostat for engine cooling is located within a Thermostat Housing. Follow the bottom radiator hose leading to engine block, where it meets teh block you will see the housing. It looks like this http://www.drivewire.com/search/?Ntt=Thermostat+housing&N=0&uts=true&t_event=true
Be sure and be careful, it is a plastic assembly and can crack when removing or reinstalling. There are torque specifications for it as well that must be observed. The torque settings are located on this pdf. They are under Thermostat Housing. http://pics.tdiclub.com/data/500/PopularTorqueSettings.pdf
You CANNOT put just any antifreeze/coolant into a VW TDI no matter what someone tells you. Even if the bottle says UNIVERSAL. If you are doing this repair and doing it right then you need PENTOSIN antifreeze/coolant that meets AVG (American Volkswagen Group) specs. Look at www.tdiclub.com for some great tips on upkeep of your car, ask questions, etc. Most of the time you can find a local TDI expert who will help free of charge just to tinker. These TDI engines are big hobby engines! Some guys have Million Milers! They also usually have extra fluids, parts, etc sitting around from helping other people!
