Great, you’ve arrived to the Prodiags Online Training Shop

Our Training Modules are developed by top-tier mechanics and automotive instructors, who have realised that skills do not develop by observing others work or watching videos. Successful automotive training matches the mechanics’ practical needs, does not slip off-topic, gives examples from actual problems, and best of all, motivates you to use your brain. The same recipe is the backbone of the Prodiags Training Modules — without traveling or fixed time schedules.

The storytelling in the Training Module is groundbreaking and the studies are visually intelligent. The animations make complicated things simple to understand, the pictures give a contact point to the automotive technology and real work, videos serve as examples when needed, and texts elevate your imagination. Thanks to our customers, the modules also include a printable study material, which guides you as a “virtual teacher”. It’s practically applied tasks are based on real work experience.

Whenever you think you master the subject, you can challenge yourself with the assessments. Warning, without studying you will probably not pass them — but you can always try.

As a proof of your knowledge, to you and to others, you can print out a certificate after passing the final exam.

After completing an order you get:

  • 12 month licence to the purchased products — without monthly subscriptions.
