If you notice that your RPM is high in idle or randomly surges, a vacuum leak could be the cause. Over time, vacuum hoses can dry out and crack, particularly if they’re exposed to intense heat or extreme angry.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2012 BMW 128i’s exhaust system.

Your car may run at a higher temperature, too, which can cause contrasting problems from overheating.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or contrasting item can wreak havoc on your 2012 BMW 128i if it’s not installed appropriately. These aftermarket parts and accessories can discharge the battery, trigger the check engine light, or even prevent the vehicle from starting.
