Answer
Hi Jennifer;
Sorry to hear about your trouble.  There is a coolant "flange" that is on the drivers side of the cylinder head that was likely the original problem.  It has a funny shaped "o" ring seal that is sort of elliptical.  There are little tabs that hold it in place, but they do come out during installation, from time to time.  My guess is that the "o" ring seal is not seated against the head tightly, and that may be a result of an improper installation technique by the technician that did the job, but is more than likely a result of not cleaning the surface off enough when the new part was put in.  There are 2 bracket holders that are also on the 2 fasteners used to hold the flange, and if they allowed to interfere will cause a leak when done.  I realize that my next suggestion is just money out of your pocket, but I would highly recommend taking the car to the local best Volkswagen dealer for a new coolant flange.  The reason I suggest going someplace else is because I think the explanation for your new leak is spurious, nefarious, and false.  I think they are liars, and you only throw good money after bad, if you go back.  I would use the money spent, as "tuition"...(as one of the other nice people said in this forum about a similar experience).  Please do some further investigation on your own.  Where is the leak?  Can you see it?  Does it come from the drivers side?  Is there a puddle of fresh coolant left when you park?  Where is that puddle?   And so on......  Arm yourself with information that will help in the further, and complete diagnosis of your vehicle.  Tell that to the service advisor when you get to the dealer.  Ask for a pressure test of the cooling system while they have the car, and also ask that before any other work is attempted they call you to discuss your options.  You could have a blown head gasket now, and the problem has just become a couple of thousand dollars, instead of a couple of hundred.  If that's the case contact your local small claims court, and get busy against the last guys to recover your payment, or at least call them, and give them the opportunity to voluntarily give you your money back.  I hate to get so deeply involved in some of these problems, but auto repair shops, and mechanics have a poor reputation, and image in the public perception, and I, like most of my fellow technicians work HARD for what we get paid.  People that use this specialty to take money without providing the service they are paid for, need to be severely curtailed.  Good luck!
