⚠️ EPS warning light suddenly appeared on your BMW’s dash?
🔧 No communication with the steering module and no power assist?
🛠 At ECU Fix, we repair BMW EPS faults quickly—with no coding and a lifetime warranty
If your BMW has no EPS, meaning the power steering assist has stopped working and the EPS warning light is on, the issue may be more than just a blown fuse or battery glitch. In fact, this failure often starts intermittently—such as after a cold start or voltage drop—and then becomes permanent over time.
Additionally, many drivers and technicians find that diagnostic tools can’t connect to the EPS module at all. This is not unusual. It usually means the fault lies deep within the EPS control unit, not in the wiring or vehicle battery.
Fortunately, at ECU Fix, we specialise in restoring communication and function to these units—without replacing the rack or needing to visit the dealer.
🔍 What Causes the BMW No EPS Fault?
BMW vehicles with electric power steering rely on an integrated control unit within the steering rack. Once that unit fails internally, communication over the vehicle’s CAN network can be lost entirely.
Most commonly, the causes include:
- Faulty voltage regulation inside the ECU
- Damaged CAN transceivers or signal pathways
- Moisture ingress causing internal corrosion
- Heat stress or repeated low-voltage starts
As a result, even though the rest of the vehicle’s systems are functioning, the EPS module will not respond, and diagnostic tools show no communication.
⚠️ Symptoms of BMW No EPS Fault
As this fault progresses, you may notice the following:
- A EPS warning light appearing intermittently, then staying on
- Heavy steering, often from the moment the ignition is switched on
- No communication with the EPS system using diagnostic tools
- The issue gets worse after starting the vehicle on a low battery
- No obvious faults in fuses, relays, or wiring
Eventually, the vehicle loses all steering assistance, making it difficult—and unsafe—to drive.
🛠 How ECU Fix Repairs BMW EPS Faults
Instead of replacing the entire steering rack, which can cost over £1,000 and require coding, we focus on repairing your original unit at the source of the problem.
Our repair service includes:

- Identifying damaged internal components such as CAN drivers or regulators
- Replacing faulty components and reflowing poor solder joints
- Simulating real-world steering conditions to verify the fix
