App technical assistant

Hello,

I am developing an app technical assistant designed for automotive repair workshops. I am currently looking for 5 professional mechanics to participate in a free beta test.

This is not a sales post, and participants will not be asked to provide payment or credit card details. They will receive a limited number of free diagnostic searches in exchange for honest technical feedback.
For each case, I would need whatever information is available, such as:
• Make / model / year
• Engine
• Fault code(s) if exist
• Symptoms
• What has already been checked
• Any measurements or diagnostic data if exist

I will enter the cases into the application and see what diagnosis and recommended checks it provides. The most important thing for me is to receive honest feedback from people with experience in the field.
If it gets something wrong, I want to know.
If it points in the right direction, I want to know that too.
thanks in advance
