Smart Sensor Solutions for Safer Driving
Welcome to Auto Electrician Hayes. Modern cars come with fantastic technology, but you don't need to buy a brand-new vehicle to get the latest safety features. We specialise in upgrading your current car with high-quality sensors and cameras.
Whether you struggle with tight parking spaces or want extra peace of mind on the road, we have the perfect solution for you.
Expert Car Sensor Repair and Electronic Diagnostics
Auto Electrician Hayes. We are not just mechanics; we are qualified Electronics Engineers.
Modern vehicles are controlled by complex networks of sensors and computers. When a warning light appears on your dashboard, many garages will tell you to buy a brand-new, expensive part. At Auto Electrician Hayes, we offer a smarter solution. We diagnose the root cause of the electronic failure and repair the unit at the component level.
We save you money by fixing the electronics you already have, rather than replacing them.
Sensor Systems We Repair
We specialise in the complex safety and control sensors that keep your car running correctly.
Steering Angle Sensors (SAS)
A faulty Steering Angle Sensor can trigger your traction control (ESP) or power steering warning lights. These units are often expensive to replace.
-
We repair the internal optical or resistive components.
-
Calibration and coding services included.
-
Fixes for "Internal Failure" error codes.
Yaw Rate and G-Sensors
Used in your car’s stability control system, these sensitive electronic devices detect skids. They frequently fail due to vibration or internal circuit faults.
-
Repair of lateral acceleration sensors.
-
Combined sensor module repairs.
-
Restoration of factory safety settings.
ABS and Wheel Speed Sensor Modules
Often, the diagnostic computer says "Wheel Speed Sensor Fault," but the sensor itself is fine. The real problem is often inside the ABS Control Module.
-
We repair the electronic board inside the ABS pump.
-
Fix connection faults and soldier joints.
-
Resolve intermittent speedometer or brake warning issues.
Radar and Parking Modules
While we do not install aftermarket kits, we repair the factory-fitted electronic modules that control your parking assist and adaptive cruise control (Radar) systems if they fail due to water damage or component burnout.
Why Choose an Electronics Engineer?
Understanding why a part failed is just as important as fixing it.
Component-Level Repair
Most garages just plug in a scanner and swap parts. We open the unit up. We use microscopes and precision soldering equipment to replace failed microchips, capacitors, and resistors on the circuit board.
Cost-Effective Solutions
Manufacturer prices for new sensor modules can be hundreds or even thousands of pounds. Our repair service is a fraction of the cost of a new unit, and often comes with a longer warranty than a used part.
Green and Sustainable
Repairing electronics is better for the environment. By fixing your existing unit, you prevent electronic waste from going to landfill.
Our Repair Process
We make it easy to get your car electronics back to full health.
Diagnostic Assessment
We test the unit to confirm the fault. We don't just guess; we use advanced bench-testing equipment to simulate the car's environment.
Precision Repair
Our engineers strip down the unit and replace the damaged internal components using high-grade materials.
