What are some reasons that my BMW 328i won’t start in the cold?

We had a cold snap recently and I didn’t turn on my car for two days. I thought it drained my battery but even a jumpstart didn’t help. What are some reasons that my BMW 328i won’t start in the cold?

It’s likely that your BMW 328i won’t start in cold weather because of a battery—but there could be other factors at play.
It sounds like you’ve already checked out the battery on your car. Check one more time, paying close attention to the terminals. When jumpstarting the battery, make sure you give it plenty of time with the donor car before you attempt to crank the BMW’s engine.
A mobile mechanic may be able to test your battery or you can do it at home with a multimeter. If you discover that your battery is old or weak, replace it and see if that solves the problem.
Cold weather can be hard on any vehicle, BMW or otherwise!
There’s one more possibility, which is that your BMW 328i has a bad car starter/solenoid. It could even be an issue with your fuel system.
If you have towing and labor coverage or AAA membership, get your BMW 328i towed to a garage for assistance from a mechanic.
