Hello everybody. I have a 2008 bmw 328i coupe 133k miles. Recently In early September the car died on me faulty battery I got a new one has been working like a charm, I don't use my car a lot I just bought it but sometimes when I leave it off for a whole day or two days it stalls for half a second or sometimes it sounds weak or maybe sometimes it stumbles upon start not hard just very small but turns on just fine, could this be alternator issue? I had the battery checked before I bought it and the guy said it won't hold a charge so he recommended I get a new one. So I did Please look at my YouTube video for more detail. The first one is a perfect start. The second one is a little bit weaker and the 3rd start is the choke/stumble it does and yes I have tried to cycle the engine sometimes on cold starts.
