I rang to ask about a whining noise from my Discovery Sport and they said bring it in and we’ll have a look - no appointment necessary, no charge. Main dealer needed 3 weeks notice and minimum of £240 just to look! Reception area was very clean and tidy. Young ladies on reception very knowledgeable and professional. Initial diagnosis by a mechanic was less bad than I’d feared. They were... Read More

Diagnostics Northampton
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.

Fantastic service this week when getting our Jeep’s MOT done at NDG!
Our car failed unfortunately due to something being split.
This was explained to us in great detail by the staff & was all sorted out on the same day, getting us back on the road!

Badly let down by the garage I'd been using for years - had my car for a week without even putting a spanner on it, and returned it scratched. Found New Duston Garage on the internet, who identified the problem very quickly, got the part, and had the car ready in a flash - everyone there first class professionals.

Garage came as a recommendation via a facebook group.
Really impressed that I was offered a courtesy car for the weekend if they couldn’t sort the problem late on a Friday evening. Fortunately it was sorted and even an apology for worrying me.
First time I’ve used this garage and I will certainly be using again in the future.
Thank you NDG. -

NDG have succeeded where other garages have failed, alignment and tracking on a range rover is not easy but NDG did a fantastic job, 4 new tyres and all of the alignment and tracking made it feel like a new car. Will be using them going forward for servicing and MOT as they have earned my trust. Great job!

Had an issue with my e class Mercedes soft close boot motor needed replacing! NDG were able to identify the part needed, order is from Merc and fit it in 2 weeks. Mercedes themselves ordered the part in August and haven’t called me back or told me if they’ve received it yet 🤣

I took a chance here as I've been badly let down by other garages who miss important checks causing me huge bills and breakdowns later or just mess you around. Most garages are dirty and never tell you what is involved or how long it will be and then you get a surprise bill at the end you weren't expecting.
Booked for a service and the place is very well organized and you are well... Read More

I contacted the garage on short notice for a repair, after them being recommended to me by another local garage. They luckily had a spot available in the week. The garage was always very polite and had great communication to let me know what the situation was with my car. The technician took the time to explain what the problem was and they also charged me a reasonable price.

Been meaning to drop these guys a positive review for ages now. Moved to Duston nearly 5 years ago and have been using them ever since. They’ve always been great, quick, good prices, friendly.

A review prompted by some minor, non-essential work needing doing and I didn’t even think to check anywhere... Read More
