BMW and MINI EWS repairs - Electronic immobilizer
Electronic immobilizer (EWS) module failure is a common problem in BMW and MINI vehicles. The EWS module enables your vehicle to start. If faulty, the car typically won’t crank and no start signal will be generated.
The EWS module is an important module in BMW and MINI vehicles for two reasons. Firstly, it functions as an anti-theft system in your vehicle. For the vehicle to start the EWS, key, and the engine control unit (ECU or DME) need to be in sync.
Secondly, the EWS stores the vehicle order (VO). The VO is essentially the coding that knows and controls all the car’s features, similar to the DNA of a human. It has information about the type of transmission, extra features, VIN, engine type, etc.
Typical signs of a faulty electronic immobilizer in BMW and MINI vehicles include:
- No vehicle crank
- Vehicle not accepting the key
- Vehicle starts and stalls
- Yellow ELV steering lock on the dash
Once the EWS module fails, it will either require a repair or replacement unit. Repairs can typically be performed if the software on the unit is corrupt, which is often caused by failed software updates or when adding additional keys with incorrect tools. If there is physical hardware damage to the unit, potentially from water or another force or decay, it will likely require a replacement EWS unit.
Regardless of the type of failure, the ECU Pro can offer you a repair service at a fraction of the OEM repair price. It is recommended that you first send your EWS for testing services. Once we have determined what is wrong with the unit, we will recommend either a repair or replacement EWS module.
