I'm not etirely sure what you mean by "out of timing" but I'll guess that you mean it's sputtering, misfiring, and running rough (when you can get it to start). If that's the case you likely have a fouled spark plug or a bad ignition coil (very common). You need to check with a VAG-COM diagnostic tool. You can borrow one for free from many autoparts stores (like Autozone). It will tell you exactly which cylinder isn't firing correctly.
