Long story short, our passat has sat in the driveway for almost 2 years now since it was believed that the transmission solenoids had failed. I starting thinking about working on it for fun and found out that flooding is a common problem due to the sunroof drain and water damaging the tcm and ccm.
I pulled out the tcm, found water damage, and cleaned with electronic parts cleaner and it works again.
been driving it for about a week, but have a couple issues;
-p0455 large vacuum leak detected, I'm thinking the gasket between the throttle body and intake
-tires are flat spotted from sitting for so long.
any other recommendations on things to check after sitting for so long?
