04 Beetle coolant temp. sensor

We have 2004 & 2005 Beetles that each have had the coolant temperature sensor replaced at least three times, and the check engine lights on both cars are on again. Our dealership seems to only want to keep replacing the sensors, under warranty, even though that does not correct the problem. Anyone have any advice on what might be going on, and what the potential fix is? Maybe vwRobert could chime in since he is probably the one who has done most/all of these repairs.

I suggest checking on your local lemon law.

Thanks for the info, but I would like to know if anyone has any thoughts on what could cause the coolant temp. sensor to repeatedly fail on these two cars.

Are you using the proper coolant?
