What's the 27a4 BMW code?

The 27A4 BMW error code may be accompanied by a no-start and refers to a malfunction with the EWS module. The EWS in the BMW is responsible for managing the communication of the starter, starter relay ignition, key and fuel systems. When a chipped key is inserted into the ignition, this module sends signals to the vehicle's starting systems to fire the engine. It works with the DME or Digital Motor Electronics to regulate starting. The DME organizes the engine's performance from emissions to fuel efficiency to optimal power distribution. The 27A4Code could indicate a serious problem with the module itself or communication issues between the DME and the EWS. Many BMW owners need to reprogRam their keys or fix the fob's internal components to clear the code.
