OEM replacement kit for the DEF heater in the 2012-2014 Passat TDI. The DEF heater is vital to keeping the DEF from freezing in the winter, and your TDI will fail emissions or refuse to start if the heater is not operational.
This kit includes the heater itself along with new securing nut, gasket and an accessory kit including zip ties and attachments for re-installation.
Note: for those that are DIY inclined, the heater repair kit for the VW Touareg can be used in the Passat TDI and is much less expensive. See the Touareg TDI AdBlue Heater Repair Kit here.
