Electrical Diagnostic Pricing

Electrical Diagnostic Pricing in Shepperton

Modern vehicles rely heavily on electronic control units, sensors and complex wiring systems. Because of this, electrical faults cannot be diagnosed by simply reading a fault code. Accurate testing requires time, experience and professional equipment.

At Walton Bridge Garage Ltd, we follow a structured diagnostic process to identify the root cause before recommending repairs. This approach prevents unnecessary parts replacement and reduces repeat visits.

Our Diagnostic Charge

We charge £108 including VAT for the first hour of diagnostic testing. During this time, we scan vehicle systems, analyse live data and carry out physical testing where necessary.

If further testing takes longer, we will contact you before continuing. Therefore, you remain fully informed and in control of costs.

Diagnostic charges cover the time required to locate the fault accurately. Repair costs are calculated separately once we confirm the issue.

What Diagnostic Time Covers

Electrical faults often require step-by-step investigation. For example, we check wiring continuity, measure voltage and resistance, inspect connectors and test components directly.

Modern systems communicate with multiple control units. As a result, we sometimes test several related systems before confirming the source of the problem.

You can learn more about our structured testing process on our Diagnostics page.

Why Proper Diagnosis Matters

Fault codes only show where the system detected a problem. They do not confirm which component has failed. Therefore, replacing parts without testing can waste time and money.

Many warning lights, including engine management, ABS and airbag systems, require systematic testing. If your vehicle displays a warning light, visit our Engine Management Light page for further guidance.

Main Dealer Comparison

Main dealers often charge higher hourly rates for diagnostic work. However, accurate testing remains essential regardless of location. We provide professional diagnostic capability with clear and transparent pricing.
