Mobile HGV/PSV Diagnostic Technician
Mobile HGV/PSV Diagnostic Technician
_Emissions & Auto-Electrical Systems_
Location: Swindon-based, with nationwide travel
Salary: £40,000-£50,000 Basic + Overtime
Job type: Permanent, full-time
Schedule: Monday to Friday, day shifts
Benefits: Company van, fuel card, specialist training and development
About the Role
This is far more than a traditional field service role.
As a Mobile Commercial Vehicle Diagnostic Technician, you'll be based from our specialist workshop in Swindon, dividing your time between supporting our workshop team and working at customer depots across the UK. You'll help some of the country's leading bus, coach and HGV operators solve complex technical problems that directly impact fleet reliability and vehicle availability.
Working on modern Euro 5 and Euro 6 commercial vehicles, you'll diagnose faults involving emissions systems, vehicle electronics and engine management using advanced diagnostics, electrical testing and live vehicle data. Your role is to understand how complex vehicle systems interact, identify the true root cause of faults and deliver practical engineering solutions, rather than simply replacing components based on fault codes.
Your work will include DPF, DOC, SCR and SCRT systems, AdBlue dosing equipment, electrical control units, sensors, wiring, CAN communication networks and associated vehicle systems. You'll also support technical investigations and component refurbishment within our Swindon workshop, helping to strengthen the specialist expertise that underpins everything we do.
No two days are the same. One day you could be diagnosing an intermittent electrical fault at a customer depot; the next, investigating a failed emissions component in the workshop or working alongside a fleet engineering manager to resolve a challenging technical issue.
If you're naturally curious, enjoy solving problems that others can't and want to build specialist expertise in one of the fastest evolving areas of commercial vehicle engineering, you'll find this role both challenging and rewarding.
About Intechnic
Intechnic is a specialist commercial vehicle emissions engineering company supporting many of the UK's leading bus, coach and HGV operators. From our workshop in Swindon and through our nationwide field engineering team, we deliver advanced diagnostics, emissions system repairs, component refurbishment and technical support that help customers reduce downtime, extend component life and improve fleet reliability.
What sets us apart is our engineering approach. We don't believe in replacing parts until a fault disappears. We believe in understanding how modern vehicle systems work together, identifying the real cause of a problem and delivering the right solution first time.
We're continually investing in specialist knowledge, diagnostic capability and emerging technologies because modern commercial vehicles demand engineers who never stop learning. Our engineers are trusted to think independently, share knowledge and take ownership of the work they do.
If you're looking for more than routine servicing and want to become part of a business where technical ability, curiosity and professional pride are genuinely valued, Intechnic offers the opportunity to build specialist expertise while supporting some of the UK's largest commercial vehicle fleets.
Key Responsibilities
Carry out mobile diagnostics and repairs at bus depots and other commercial fleet locations.
Diagnose mechanical, electrical and emissions-related faults on buses, coaches and HGVs.
Investigate Vehicle and exhaust-aftertreatment problems.
Diagnose faults involving sensors, wiring, connectors, dosing systems and control units.
Use professional diagnostic equipment, electrical testing tools, live data and wiring diagrams.
Identify the root cause of faults rather than relying only on fault codes or replacing components unnecessarily.
Remove, inspect, repair and replace emissions and exhaust-system components where required.
Work closely with customer engineering teams to return vehicles to service safely and efficiently.
Complete accurate job sheets, inspection reports and supporting photographs.
Explain technical findings and recommendations clearly to customers.
Maintain the company van, tools and diagnostic equipment in good working condition.
Follow all company and customer health and safety procedures.
Represent Intechnic professionally and deliver a high standard of customer service.

Proven experience as an HGV Technician, PSV Technician, Bus Technician, Commercial Vehicle Technician or Diagnostic Technician.
Strong understanding of commercial-vehicle electrical and electronic systems.
Excellent diagnostic, fault-finding and problem-solving skills.
Ability to interpret wiring diagrams, diagnostic information and live vehicle data.
Confidence investigating complex faults involving several connected vehicle systems.
Experience using diagnostic and electrical testing equipment.
A methodical and accurate approach to technical work.
Ability to work independently and manage a mobile workload effectively.
Good communication and customer-service skills.
High standards of workmanship and attention to detail.
