Understanding the difference in diagnostics – why choose us for your vehicle diagnostics in the North West - 01744 808586
Enjoy convenience when it comes to your car diagnostics -
When your car or van develops a fault, the first step to getting it back on the road is a diagnostic check. But not all diagnostics are the same! At Fastlane Autocare - Autocentres, we offer two types of diagnostics: main dealer-level diagnostics and generic diagnostics, giving you the best choice for your vehicle and budget.
Main dealer-level diagnostics – precision and accuracy
We invest in main dealer diagnostic equipment, meaning we can provide the same level of fault finding as a dealership, but with a more convenient and cost-effective approach. This is ideal for modern vehicles that have complex electronic systems and require specialist knowledge.
We hold specialist diagnostics for brands including:
-
BMW
-
Mini
-
Audi
-
VW
-
Skoda
-
SEAT
-
Mercedes-Benz
-
Aston Martin
-
Jaguar
-
Land Rover
-
Bentley
-
Ferrari
-
Lamborghini
Using manufacturer-specific tools means we can:
-
Access all ECU systems, including engine, transmission, ABS, and body control modules
-
Perform live data monitoring to pinpoint faults quickly
-
Reprogram ECUs and update software
-
Carry out coding for new components, including keys, injectors, and control units
This level of diagnostic is essential for premium and performance vehicles, ensuring they get the attention they deserve without the expensive main dealer price tag.
Generic diagnostics – A cost-effective option for many vehicles
For many cars and vans, a generic diagnostic scan is all that’s needed. Our generic diagnostics provide an efficient and affordable way to read fault codes, reset warning lights, and check vehicle health.
-
Ideal for most vehicles
-
Checks common issues such as engine faults, airbag lights, and ABS warnings
-
Quick and budget-friendly
-
Perfect for pre-MOT checks and troubleshooting minor issues
While generic diagnostics can identify many issues, they may not access manufacturer-specific systems. In some cases, if a fault is detected, we may recommend a dealer-level scan for further investigation.

FAQ – Understanding the Difference in Diagnostics
Q: What is the difference between main dealer diagnostics and generic diagnostics?
A: Main dealer diagnostics use manufacturer-specific tools and software to access all electronic systems in a vehicle, allowing for precise fault detection, ECU programming, and software updates. Generic diagnostics, on the other hand, provide a basic scan of fault codes and warning lights but may not access all systems in modern vehicles.
Q: Do I need main dealer diagnostics for my vehicle?
A: If you own a premium or performance vehicle such as BMW, Audi, Mercedes, Aston Martin, or Jaguar, main dealer diagnostics are recommended. These vehicles have complex electronic systems that require specialist tools for accurate fault-finding and repairs.
Q: Is generic diagnostics suitable for my car?
A: Generic diagnostics work well for many standard vehicles and can identify common issues such as engine faults, ABS problems, and airbag warnings. If a more in-depth analysis is needed, we may recommend upgrading to a main dealer diagnostic scan.
Q: Is main dealer diagnostics more expensive than generic diagnostics?
A: Main dealer diagnostics typically cost more due to the advanced equipment and software required. However, we offer this service at a lower cost than main dealerships while maintaining the same level of accuracy and expertise.
Q: Can I book a same-day diagnostics appointment?
A: Yes, we offer same-day and next-day diagnostic appointments at our North West diagnostics centre, depending on availability.
Q: Which vehicle brands do you offer main dealer diagnostics for?
A: We provide main dealer diagnostics for brands including BMW, Audi, VW, Skoda, SEAT, Mercedes-Benz, Aston Martin, Jaguar, Land Rover, Bentley, Ferrari, and Lamborghini.
Q: Can you reset warning lights after a diagnostic check?
A: Yes, if the issue has been resolved, we can reset warning lights. If a fault remains, we will provide advice on the necessary repairs.
Q: Do you offer mobile diagnostics?
A: Yes, we provide mobile diagnostics for vehicles that cannot be driven to our centre. However, some advanced dealer-level functions may require the vehicle to be brought to our workshop.
Q: How do I book a diagnostics appointment?
A: You can book an appointment by calling us or visiting our North West diagnostics centre. We offer flexible booking options to suit your schedule.
