Vehicle Diagnostics in Plymouth
At Plymouth Motor Company, we specialise in advanced vehicle diagnostics and fault finding across all makes and models using dealer-level diagnostic equipment and the latest diagnostic technology.

Modern vehicles rely heavily on complex electrical systems, control modules and onboard computers, meaning accurate diagnostics are essential when faults occur.

Our experienced team includes master technicians with extensive diagnostic knowledge and experience, allowing us to identify and repair faults that many garages struggle to resolve.

Modern Vehicle Diagnostics
Modern vehicle diagnostics are far more advanced than simply plugging in a code reader and replacing parts.
Fault codes only tell technicians where a fault has been detected or logged within the system — they do not automatically identify which component requires replacement.
Correct diagnostics involves analysing live data, assessing system operation, checking wiring diagrams, carrying out electrical and mechanical testing and following a structured diagnostic process to accurately identify the root cause of a fault.
As vehicle technology continues to evolve, modern diagnostics requires ongoing investment in equipment, technical information and training to ensure faults are diagnosed correctly and efficiently.
At Plymouth Motor Company, we take a methodical approach to diagnostics to avoid unnecessary parts replacement and help resolve faults properly the first time.

Advanced Fault Finding
We carry out in-depth diagnostics for a wide range of vehicle issues including:
  • Engine Management Lights
  • Electrical Faults
  • Starting & Charging Problems
  • DPF & Emissions Faults
  • ABS & Airbag Warnings
  • Sensor & Communication Faults
  • Air Conditioning Faults
  • Running & Performance Issues

We have invested heavily in dealer-level and multi-brand diagnostic equipment to allow us to diagnose faults accurately across a wide range of modern vehicles while keeping repairs and testing in-house wherever possible.
