2000 VW Beetle Diesel not started in three months (Boston). After new battery, car started, ran rough for five seconds and died. Are there special considerations when trying to start a car that has been sitting this long? I could put the old battery in (75% charged) and try to start it again. Thanks Barbara

3 months isn't much. But make sure you have a full battery charge,, and if it still acts up, have a VW mechanic check it out cause just changing the battery on those can cause resets to be needed
