Specialist HGV & Truck Diagnostics
Access dealer-level diagnostic capability for commercial vehicles without dealer-level delays.
When Standard Diagnostics Isn’t Enough
Complex Fault Diagnosis
Our experience is built on diagnosing faults other workshops have already failed to resolve. Using dealer-level diagnostics and real-world electrical and emissions testing, we identify the true root cause of vehicle issues, helping operators avoid expensive guesswork and unnecessary parts replacement.
KEEPING FLEETS MOVING
We diagnose faults properly before parts are replaced. By identifying the true cause of vehicle issues, we help transport operators avoid expensive guesswork, prevent repeat failures, and keep vehicles working when they’re needed most.
EXPERT SUPPORT, WHERE YOU NEED IT
KWS TruckTech provides mobile diagnostics, fault investigation, and technical support for fleets and workshops. We attend vehicles on-site to diagnose faults accurately, helping operators avoid expensive guesswork, reduce recovery costs, and get vehicles back into operation faster.
About Us
KWS TruckTech was established to address a growing skills gap in modern commercial vehicle diagnostics. As HGV systems have become more complex, many transport operators and workshops face ongoing challenges with misdiagnosis, unnecessary parts replacement, and repeat vehicle breakdowns. Our goal is to provide specialist HGV diagnostics and truck fault finding support that focuses on identifying the true root cause of vehicle faults before major components are replaced.
With over 15 years of hands-on experience working across European HGV brands including Scania, Volvo, DAF, MAN and Mercedes commercial vehicles, KWS TruckTech provides advanced truck diagnostics, HGV electrical diagnostics, emissions system fault diagnosis and CAN network fault tracing. We use dealer-level diagnostic platforms combined with real-world electrical testing and fault investigation methods to diagnose complex commercial vehicle faults accurately and efficiently.
KWS TruckTech was built from real workshop experience and first-hand exposure to the frustration caused by repeat faults, unresolved warning lights, and expensive repairs that fail to fix the underlying issue. We regularly support fleets and workshops dealing with complex truck faults, intermittent electrical issues, AdBlue and SCR system faults, DPF fault diagnostics, and communication network faults on modern Euro 6 commercial vehicles.
Our approach is focused on accurate diagnostics and targeted repairs. By identifying the root cause of faults early, we help transport companies avoid unnecessary parts replacement, reduce repeat repair costs, and maintain reliable fleet performance. We believe that correct diagnosis is the most important step in any repair process, particularly as modern HGV electronic and emissions systems continue to become more advanced and software driven.
Based in the UK and supporting fleets across Doncaster, South Yorkshire and surrounding areas, KWS TruckTech provides specialist mobile truck diagnostics, on-site fault investigation and technical diagnostic support for fleets, workshops and commercial vehicle operators. Our focus is to provide reliable, technically accurate diagnostic support that keeps commercial vehicles working efficiently and helps businesses reduce costly downtime.
