Perfect fit easy install
The coolant light came on and the dealership wanted to charge me $700 for a water pump replacement. I guess some German engineer designed the car so you have to remove the motor mounts and jack up the engine to get to the water pump and serpentine belts. While I was contemplating whether I should pay the $700 to keep a twelve year old car or dump it I discovered that the hose attachment on the reservoir was cracked and coolant was leaking out. I replaced it with this baby and no more coolant light. Happy me.

Perfect replacement
I just recently bought one of these a month and a half ago for my TDI Passat fit perfect no issues. I also purchased another one almost two years ago for my Jetta.. that also fit perfectly and has given me no issues since the install.. would definitely recommend this.. one of my OE hose nipples broke off of the 07 Jetta I wish I knew how cheap and easy this was to replace. I would have replaced it before it broke..

Buy original manufactured volkwagon
The sensor does not slip on in a 2009 Jetta. I left it thinking it would not cause an issue. 6 months later the coolant is leaking out into the sensor. I think it may have been forced on at some point by someone, but still… I would go with Volkswagen made

(Fix and edited) Fits Great, Except for the Sensor Connection
Replacement for a MkV Jetta with a 2.5L. Fits perfectly fine. One problem, the sensor connector is just slightly too long, causing the "Low Coolant" light to come on every time I start the car. Does anyone have a fix for this? Here's the fix. Inside the connector (The bit attached to the car, yeah, the one with the wires sticking out of it), there is a spacer. Mine was purple. If you stick a small screwdriver or pry tool into the connector, and slide the spacer to the side of the connector with an access port, and pull it all the way out: Tah-dah! It'll fit like a glove. Not sure what I'm talking about? See the attached pictures.
