The car popped a "Service AWD" light yesterday, so she's going to drive my car until I get back.
She also found herself a forum for her car, found others with the same issue and also learned quite a bit about her car.
She found a small leak from the rear diff, and that coupled with the PTU issue that is causing the light, she's hesitant to keep driving it.
Here's the link to the thread: http://www.200forums.com/forum/58-20...eel-drive.html
It's covered under the factory warranty, so I'm not gonna lose sleep over it. She just wants to wait until I get back to take it in.
