Does this sound familiar?

You bought a scanner but don’t understand most of the features
Mechanics give you vague answers or quote huge repairs without showing proof
You want to check if something like a turbo or CAT is bad—without guessing
Electrical diagnostics feel confusing and overwhelming
You KNOW you’re being overcharged but don’t know what to do

DIY Car Diagnostics Course

I built this course for people just like me a few years back—DIY mechanics who wanted answers but didn’t have a shop full of tools.

✅ No fluff. No hour-long boring videos.
✅ Just step-by-step instructions with real tests, real cars, and real tools.

I already have short OBD-II scanner course on Udemy with over 1100 students. It is about 5% of knowledge and quality you are getting in THIS training.

Why This Course?

You don’t need to be a pro mechanic. You just need to understand what your tools are telling you. This course covers:

How to use your OBD2 scanner like a pro (even the cheap ones)
How to test sensors, wiring, and circuits with a multimeter
How to verify failed parts using live data and simple tricks
How to avoid shop scams by knowing what actually needs replacing

Course plan - Lesson overview

The first 3 modules are all about building your diagnostic foundation:

Learn how to use OBD2 scanners the right way
Understand live data, freeze frames, and fault codes
Get hands-on with multimeters, test lights, scopes, and more

After that, we start testing real components:

Catalytic converter, turbocharger, vacuum leaks, injectors
Engine compression, oxygen sensors, fuel pressure, and more

New diagnostic lessons are still being added—once you join, you get lifetime access to all updates. Even if you just do 15 minutes a day, this course will move you from guessing parts to actually diagnosing problems like a pro.

What happens after I pay?

How much I need to spend on tools?

Is this one-time payment?

Will I learn to do everything on any car?

I am helping friends & family on weekly basis with their cars and I love that I can take that stress from their shoulders.

And I am not saying you should start repairing everything on car yourself.

I don't do that either.

But now when I take car to shop I just ask them to replace what I already know is bad and I don't want to replace it myself.

Even 15 minutes a day can make you confident with your car in 30 days.
