Fault diagnosis and electrical repairs you can rely on, right here in Liverpool.
A Diagnostic Inspection is a structured fault-finding process carried out by our technicians to identify the cause of a warning light, fault message, electrical issue, performance problem or other vehicle concern.
If the fault is something we can fix within the first hour, we’ll do our best to get you back on the road as quickly and affordably as possible.
For more complex problems, we’ll carry out fully detailed diagnostics. If it requires more than an hour of work, we’ll explain the next step before any additional repair work or cost.
All diagnostic work comes with a diagnostic report, so you know what’s been checked and what we’ve found. We keep you informed throughout, with clear advice before any repair work goes ahead.
Dashboard Warning Lights & Fault Messages
Warning lights on your dashboard can be worrying, but it doesn’t always mean something serious. We’ll run a full diagnostic check to identify the issue, clear fault codes where possible. If repairs are needed, we’ll always provide a clear explanation and cost breakdown before proceeding.
From engine management lights and battery warnings to ABS, airbag, DPF, AdBlue and brake warnings, our team can diagnose the issue properly before repair work begins.

Car Keeps Blowing Fuses?
If a fuse in your car keeps blowing, replacing it again is not the answer. A repeated blown fuse usually means there is an underlying auto electrical fault that needs proper testing.
Common causes can include damaged wiring, short circuits, water ingress, faulty components or previous repairs that were not carried out correctly. Our auto electricians can test the circuit, trace the cause and explain the right repair before work goes ahead.
- Fuses that keep blowing after replacement
- Short circuits and damaged wiring
- Water ingress affecting electrical circuits
- Faulty lights, wipers, sensors or accessories
- Faults caused by aftermarket electrical upgrades
- Previous poor electrical repairs
Electrical Warning Signs to Watch Out For
If your car or van is showing dashboard warnings, flickering lights or unusual electrical behaviour, it’s a sign something isn’t right. Ignoring these symptoms can lead to breakdowns, repeat faults or more expensive repairs, so it’s best to have the vehicle checked by a qualified auto electrician.
- Warning lights that won’t clear: engine, ABS, airbag or DPF alerts
- Electrical glitches: intermittent lights, wipers, or locking issues
- Slow starting issues: possible battery, alternator or starter motor issue
- Faulty sensors or parking aids: parking sensors, cameras, or ADAS systems
- Dim or flickering lights: voltage drops or poor connections

Your questions answered
What is a vehicle diagnostic test?
A diagnostic test uses specialist equipment to scan your vehicle’s onboard systems and identify fault codes or irregular sensor readings.
It quickly pinpoints the cause of dashboard warning lights or electrical issues.
Is a diagnostic test the same as fixing the fault?
No. A diagnostic test helps identify what is causing the issue, but repair work may still be needed afterwards. At Liverpool Auto Care, we explain what we have found before any additional work goes ahead.
What can cause electrical faults in cars?
Common causes include corroded wiring, blown fuses, failing sensors, battery or alternator issues, and control module faults. Modern vehicles rely on complex electronics, so accurate diagnosis is essential.
Can you diagnose intermittent vehicle electrical faults?
Common causes include corroded wiring, blown fuses, failing sensors, battery or alternator issues, and control module faults. Modern vehicles rely on complex electronics, so accurate diagnosis is essential.
Do you repair dashboard warning lights?
Yes. We diagnose warning lights such as engine management, ABS, airbag, DPF, battery and brake warnings. Once we identify the cause, we can advise on the repair needed before carrying out any work.
Will clearing a fault code fix the problem?
Not always. Clearing a fault code may remove the warning temporarily, but if the underlying fault is still present, the light is likely to return. Proper diagnostics help find the cause rather than just clearing the code.
Can a weak battery cause electrical faults?
Yes. Modern vehicles rely on stable voltage, and a weak battery or charging issue can trigger warning lights, fault codes and unusual electrical behaviour.
