Specialist HGV & Truck Diagnostics
Access dealer-level diagnostic capability for commercial vehicles without dealer-level delays.
When Standard Diagnostics Isn’t Enough
adas calibrations
Modern HGVs rely on Advanced Driver Assistance Systems (ADAS) to maintain safety and compliance on the road. With recent updates to guidance such as DVSA standards and the evolving Guide to Maintaining Roadworthiness, expectations around ADAS calibration are tightening across the industry.
It is now increasingly expected that ADAS systems are recalibrated following windscreen replacement, suspension work, or accident repairs — with enforcement only moving in one direction.
At KWS TruckTech, we provide professional, mobile ADAS calibration for heavy vehicles, carried out at your premises to minimise downtime. Using dealer-level equipment and real-world diagnostic expertise, we ensure systems are calibrated correctly, first time.
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 don’t guess. We find the fault.
Too many trucks end up with parts thrown at them hoping something sticks. That’s where costs spiral and problems come back. We take the time to diagnose the issue properly, fix the actual cause, and get it sorted once — not three visits later.
Less downtime, less wasted money, and trucks that stay out working instead of parked up waiting for another “try this” repair.
EXPERT SUPPORT, WHERE YOU NEED IT, when you need it
About Us
KWS TruckTech was built to fix a problem that’s become far too common in the industry — trucks being misdiagnosed, parts being replaced unnecessarily, and faults coming back again and again.
With over 15 years of hands-on experience across brands like Scania, Volvo, DAF, MAN and Mercedes, we specialise in proper HGV diagnostics and electrical fault finding. We’re not guessing, and we’re not relying on fault codes alone — we combine dealer-level diagnostics with real-world testing to find the actual cause of the problem.
Our work comes from the kind of jobs others struggle with: intermittent electrical faults, CAN network issues, AdBlue and SCR problems, DPF faults, and ongoing issues that haven’t been resolved properly the first time.
KWS TruckTech isn’t built around theory or office-based support — it’s built from real workshop and roadside experience. We know the cost of downtime, repeat failures, and wasted parts, so our focus is simple: diagnose it properly, fix the cause, and get the vehicle back working.
Based in the UK, we provide mobile diagnostic support to fleets, workshops, and operators who need accurate answers — not guesswork.
