I need to change it but can't seem to locate it
Where is the heat sensor located on the 2005 New Beetle? on 2005 Volkswagen Beetle
Which heat sensor? Do you mean the ambient temp sensor? If so, go to www.alldatadiy.com This site will have the repair manual info and it is very reasonable, and it will have locations of the sensor, just do a search in the upper right part of the screen.
