My fiancéas 2002 vw beetle was running rough after she checked the oil. Realized oil tube had broke and wire hooked to tube had come loose. Fixed wire and tube. Check engine light was on. Me being new to vw and having been a dodge or Chevy man all my life make the mistake of taking battery cable loose to reset everything. Well it didn't work. Now car turns over without cranking. Any ideas what is wrong?
