Took my car in for a service. Honest, friendly folk and beat the main dealer price for a service by a big margin. They offer curtesy car as well as pick up/delivery. Couldn’t ask for more. Will definitely use again!

New Duston Garage has made significant investments in cutting-edge diagnostic equipment and training to stay abreast of the constantly evolving technology in modern vehicles.
We mainly use dealer diagnostic platforms and equipment, backed up with a number of generic tools including Autel and Autologic. This allows us not only to interface with manufacturers for software downloads but also to program new components effectively.
With access to dealer equipment and comprehensive information, we stand on par with main dealers. This grants us the ability to retrieve detailed information such as wiring diagrams, repair manuals, manufacturer technical bulletins, security data, and digital service histories, among other critical data.


Can you diagnose all brands?
We have an extensive range of diagnostic systems, ensuring comprehensive coverage across all major makes. This includes dealer diagnostic platforms and equipment, along with a number of generic tools and various other specialised equipment. These tools enable us to accurately diagnose the complex systems found in today’s modern vehicles.
We work with a range of advanced automotive diagnostic systems, including:
- BMW OSS system
- VAG Odis system
- Ford IDS and Etis
- Vauxhall Tech3 and InfoTech
- Jaguar Land Rover Topix

Training Excellence at NDG
While having the necessary equipment to communicate with your vehicle is crucial, possessing the skills and knowledge is equally paramount.
Our entire team, from our experienced Mastertech to our freshly qualified technicians, undergoes continuous training.
We’re fortunate to have a dedicated training center right on site — AutoiQ.
This center offers a comprehensive array of technical courses that greatly benefit our NDG staff, granting them access to top-notch automotive training.
What diagnostics services can you offer me?
We provide a code read service for while you wait, but please ensure you book an appointment with us beforehand. This offers a record of fault codes and their explanations. Please note, this may not provide a definitive answer to warning lights or performance issues, as codes can be general.
For a comprehensive diagnosis, we recommend our detailed diagnostic service. Our Mastertech conducts a thorough vehicle scan, checking for updates, technical bulletins, known faults, and more. This hour-long service includes component and wiring inspections.
If the issue persists or needs further testing, we’ll create a diagnostic plan. Most faults are resolved within this hour. If not, we’ll provide a detailed plan and associated costs for further diagnosis and resolution.

At NDG Northamptonshire, we specialise in diagnosing and resolving various car issues, including:
- Poor performance
- High fuel consumption
- Anti-lock braking concerns
- Engine misfires
- MOT emission failures
- Airbag issues
- Engine management light alerts
- Poor starting
- Fuel injection troubles
- Electronic diesel control challenges

Code read & scan
Our technician conducts a diagnostic check by reading and storing fault codes from the vehicle. This process involves performing a simple code read, which reveals any stored fault codes.
However, it’s important to note that while this procedure provides insight into potential issues, it may not always accurately pinpoint the specific faults present in the vehicle.
Some fault codes retrieved during this process can be rather general and not entirely component-specific. For instance, a code indicating low fuel pressure might not precisely identify the exact component causing the issue.

Comprehensive diagnostics check
Our Diagnostic Technician devotes one hour to conduct a comprehensive assessment, which includes checking codes, searching for manufacturers’ software updates, examining manufacturers’ bulletins for known faults and fixes, and thoroughly inspecting components and wiring.
This thorough evaluation aims to address a wide range of potential issues within the vehicle.
If the fault is intermittent or necessitates further repairs beyond the hour, we’re equipped to devise a detailed diagnostic plan to effectively resolve the problems. Often, many faults are successfully addressed within this hour-long diagnostic session.
