CAR DIAGNOSTICS IN LEYLAND

When a warning light appears or your vehicle is not performing as it should, identifying the actual cause of the problem is essential. At North West Garage Services, we provide professional car diagnostics in Leyland for cars and light commercial vehicles of all makes and models. Modern vehicles rely on increasingly sophisticated sensors, electrical systems and onboard computers. Diagnostic equipment can reveal stored fault codes, but understanding what is causing them often requires further testing and mechanical experience. Our team combines professional diagnostic technology with decades of hands-on knowledge to investigate faults accurately, explain what we have found and recommend the appropriate solution.

WE CAN INVESTIGATE A WIDE RANGE OF VEHICLE FAULTS

Whether you have a persistent dashboard warning light, an intermittent electrical problem or a vehicle that simply does not feel right, our diagnostic service can help identify where the problem lies. We have dealer-level diagnostic software for Land Rover, Jaguar, Volkswagen, Mercedes, Audi, Skoda, Seat, Peugeot, Citroen and new Vauxhalls.

OUR DIAGNOSTIC SERVICES

PROFESSIONAL FAULT FINDING FOR YOUR VEHICLE

From dashboard warning lights to difficult intermittent faults, we combine diagnostic technology with practical mechanical testing to identify problems accurately. Our technicians work across all makes and models, including petrol, diesel and hybrid vehicles, helping you understand what is wrong before unnecessary parts are replaced.

ENGINE MANAGEMENT DIAGNOSTICS

We investigate engine management warnings, running problems and stored fault codes to identify the underlying cause and recommend the appropriate repair.

ELECTRICAL FAULT DIAGNOSIS

From faulty sensors and intermittent electrical issues to battery and charging problems, we use professional equipment and practical testing to trace faults accurately.

DPF & EMISSIONS DIAGNOSTICS

DPF warnings, failed regenerations and emissions faults can have several possible causes. We investigate the complete system rather than simply clearing the warning light.

ABS & SAFETY SYSTEMS

We can diagnose warning lights relating to ABS, airbags and other electronically controlled safety systems, helping determine where further testing or repairs are required.

WHY CHOOSE US

METHODICAL DIAGNOSTICS, NOT GUESSWORK

Vehicle diagnostics should involve more than plugging in a computer and replacing the component mentioned in a fault code. At North West Garage Services, diagnostic information forms part of a wider investigation. Our technicians combine fault codes, live vehicle data and practical testing with years of mechanical experience to identify what is actually causing the problem. We keep you informed throughout and explain any recommended repairs before carrying out additional work.

EXPERIENCED TECHNICIANS

Decades of hands-on mechanical knowledge help us interpret diagnostic information and investigate faults properly.

STRAIGHTFORWARD ADVICE

We explain what we have identified, what requires attention and the options available before repairs begin.

ALL MAKES & MODELS

Diagnostics are available for cars and light commercial vehicles across a wide range of manufacturers.

PROFESSIONAL EQUIPMENT

Modern diagnostic equipment allows us to access fault codes, live data and electronically controlled vehicle systems.

METHODICAL FAULT FINDING

We work through potential causes logically instead of replacing parts based solely on a stored fault code.

DIAGNOSIS & REPAIR

Where repairs are needed, we can source the required parts and complete the work at our Leyland workshop.

VEHICLE DIAGNOSTICS

COMMON FAULTS WE INVESTIGATE

Our diagnostic service covers everything from dashboard warning lights to intermittent electrical faults and difficult performance problems.

DASHBOARD WARNING LIGHTS

Engine management, ABS, airbag, battery, DPF and emissions warning lights can indicate a wide range of faults. We can identify the stored information and investigate the cause.

ELECTRICAL & SENSOR FAULTS

Modern vehicles contain numerous sensors and electrical components. We can investigate intermittent faults, starting problems, charging issues and other electrical concerns.

PERFORMANCE & RUNNING PROBLEMS

Loss of power, poor running, difficult starting and recurring faults can require more detailed investigation. We combine diagnostics with practical testing to determine what is happening.

I had been told a good few months ago that the rattling on my Evoque was for a timing chain, had been quoted £2.5K+ by a couple of different garages and told it would be months of a wait. As soon as I spoke to Matt he was very very approachable, had the time to speak and was very helpful with getting the vehicle in swiftly. He then called me the day of my repair to tell me the issue wasn’t my timing chain, and did himself out of a decent pay day, all so that I wasn’t spending money I didn’t need to. Some welding later and the rattling is completely gone. Honesty and service like this is hard to come by. What a guy/garage. Very professional and friendly outfit.
