2012 VW CC 2.0tsi not starting
I have a 2012 VW CC sport. It has had a front and rear end collision and as a result its had a drain on the battery for some time now. Not usually that big of a issue, just a quick jump would get it going. Not anymore. While trying to jump it one day it all of a sudden just started whirring but not engaging the flywheel. Initial thought was somehow burned out starter solenoid. Got the starter off and charged the battery and while having everything in the shop decided to do a bench test on the starter just to see. It seemed to work just fine. So i reinstalled everything and tried to give it a go and again just whirring but no engaging. All connections and cables seem to be clean and fine. Dont have alot of room in the pocketbook to fix parts that dont need it so was wondering which i should replace? Starter or battery? And why would the starter appear to work fine on a bench test but not in the car? Any advice and help on this issue would be phenomenally appreciated. Car has been idle for 3 months now due to finances and this issue. Please help.
