Hey fellas. Every BRM Jetta made for North America was equipped with the 3C0-129-607-BE air cleaner assembly with the cold weather equipment. It has the connection under the MAF for the hose from the shroud around the exhaust to allow heat past a thermostatic valve to allow the engine to breath some warm air during warm up in cold weather.
I had to order as new air cleaner assembly as the one on my new project BRM was all busted up. I ordered a lot of parts, including the air cleaner, from the parts catalog of a dealer that I get my parts from when I mail order. The air cleaner that was listed for the 2006 TDI Jetta was 3C0-129-607-BD, so that is what I ordered. The BD part differs from the original BE box in that it does not have the cold weather provisions. There is no where for that lower heat hose to connect. It’s blocked off flush.
The dealer said they would swap it for me if I sent it back as they are both the same price. I’m thinking about just keeping this one. That thermostatic flap is always broken open so there is always some hot air entering the air cleaner. By using the BD box I could delete that function and ensure only cool outside air entered the box. You still have to have the shroud installed as it is a mounting location for the hot side CAC tube.
What would y’all do?
