Yes, Temp II sensor is common among VWs and inexpensive.  Also a frequent
failing part, so even if it isn't the cause of your current problem you are
wise to have a spare available onboard.
    I think you can actually take the temperature gauge sender...it's the
other one that looks sort of the same but is black not blue (on my van
anyhow with a Jetta motor) and you can switch the two...I could be wrong on
this interchange suggestion..regardless, they're cheap.  You can probably
get one at a chain autoparts, even.
