Fairly recently installed new battery in garage kept bmw 325xi wagon. Have been driving other vehicle for a few weeks then reparked bmw outside for a few days in cold weather. Now in warm weather would not then start or even begin to turn over. Sounds like no electrical connection at all. Will not even begin to turn over.
Sounds like no electrical connection when attempting to start on 2006 BMW 325xi
Check the battery and the cables, maybe a cable was not tightened all the way.
