Thats not the problem then,there are hundreds of reasons why a car engine runs rough as you say its a process of iimination or take it to a BMW specialist.

If you cover no more than 100 miles per day and have easy access to a charging point at home or work, then an EV is ideal for you.

Is an electric car right for me?
