A coworker of mine has an 03 Jetta Wagon with the O1M trans and the small three way connector next to the vacuum pump broke while driving down the highway. It looks like one line goes to the EGR cooler, one runs back to the expansion tank and the other on runs to the upper radiator hose coupling. That of course caused coolant to drain and the car overheat which caught his attention. I helped him try to replace the fitting and in the process broke the opposite end fitting on the upper radiator hose coupling. Part of it is I think the plastic may be brittle but the first one breaking on its own may be something more. The car appears to run fine provided you dump coolant into it. I have around the same amount of miles on my beetle however mine is manual and I have never had this issue. With all of this being tied into the transmission I didnt know if this was a trans related issue or something different. Any thoughts are appreciated. thanks fellas
