Cummins Inline 6 Full Package

Global Diagnostics were highly recommended to us during the search for a software solution needed for our work on construction equipment, went above and beyond with technical expertise to tailor our package and provided superior onsite support. Their systems work exactly as intended so we have no hesitation in endorsing the GD team and look forward to working with them again in the future.

Quick delivery, good product

Only tested on a GL350 so far, easy too diagnose. Looking foreward to explore more of all of the possibilities this package offers.

Very Helpful Team

Unfortunately this did not work on my 2016 Jaguar XE. However, the team were extremely helpful in setting the software up and getting it working on my laptop. While I could link to my car, I was unable to see the ecus.
Global Diagnostics were again very generous with their time trying to resolve the issue and were then happy to issue a refund at my request. While disappointing that the software did not work with my car I can't fault the customer service from the team.

Good system

Worked out of the box has communicated with all CNH tractors I have used it on and also cleared fault code off McCormick tractor with Iveco engine. Good communication from Global Diagnostics will deal with them again.

Fantastic product, does everything I need for my Iveco Daily 2015. Jay at Global Diagnostics was really helpful too 👍

PEUGEOT PP2000 Diagbox Interface Full System

A perfect company.

I would like to share my experience so that others can feel free to buy from Global Diagnostics.
What happened.
The purchased diagnostic system did not work for some reason (probably an automatic update by Windows) I called the technical colleague in the evening and he answered immediately to enable remote access. I connected the next day and he solved the problem remotely.
This is a perfect example of how a business should work.
I wish you much success and customers in the future.

Worth Every Penny!

Very happy with the product. Arrived ready to use and works everytime so far. Very impressed considering a Genuine VCI is 3x the price and not including a laptop and software license. Customer support via WhatsApp is also top-notch. They know their stuff and responds fast. Will buy from them again.
