Review on 🔥 Efficient Heating Performance Unleashed: Spectra Premium 98030 Heater Core by Chad Black

2014 Passat TDI. The plastic pieces had to be removed to fit the slot it goes in. O-rings will not stay in groove causing them to be sheared off when attempting installation. In this case, the joint will not seat properly and the O-rings will become unusable. Unsuccessful attempt to use the old o-ring (last try). After several disassemblies and installations, one of the pipes came loose at the soldering point on the heating heat exchanger. It's not a slip joint like you see with the plumbing. Bad design. I'm not sure if this is even the right part for my car. Update: This is not the VW P/N 561819031C required for the 2014 Passat TDI SEL Premium. This is an earlier "A" version that appears to have been built for an earlier model year.
