🔧 BMW 4 Series – Restraint System Fault & Electrical Faults
This BMW 4 Series came to BMworkshop.ie – Independent BMW Specialists with multiple warning messages, including:
⚠️ Restraint System Fault
⚠️ Fuel Supply Fault
⚠️ ABS System Faults
After carrying out a full diagnostic inspection, we found no communication with the airbag control module.
The faulty module was replaced with a new Genuine BMW control module, followed by programming and coding to the vehicle.
✅ Airbag system communication restored
✅ Faults cleared
✅ Module programmed correctly
✅ Vehicle returned to the customer
When multiple warning messages appear at the same time, accurate diagnostics are essential to identify the actual root cause rather than simply replacing parts.
