Completely new to this site and need some help with an issue that has arisen with my 2004 bmw 318ti se compact. The vehicle initially cut out the other day as i was driving home from work, the vehicle was given a jump start and i made it home. I was advised given the age of the vehicle it needed a new battery. Which i replaced. This then meant the vehicle ran fine most of the day, then the same issues arose but i found that by leaving it turned off for a few minutes it would eventually come to life for an uncertain amount of time.
I have no idea anymore, im told it could now be the alternator?
Any ideas would be much appreciated !!
