NEW EPISODE: DIAGNOSTIC DETECTIVE IS LIVE

A car rolls into the workshop…
❌ Random fault
❌ No obvious cause
❌ Customer already spent money

Time to investigate.

This one had me questioning EVERYTHING… until the real culprit revealed itself.

👀 Can you solve it before I do?

I found 3 different ways to lower a Porsche Cayenne Turbo…

1️⃣ 3D printed suspension links
2️⃣ DIY hardware store solution
3️⃣ A method that requires NO parts at all

The last one surprised me the most.

It turns out… you can lower the car just by changing what the suspension thinks is normal.

Porsche actually sold a factory upgrade that turns a Cayenne Turbo into a Turbo S… 👀

Not a tune.
Not aftermarket parts.

A genuine Porsche performance kit that increases power from 500 hp to 540 hp using factory components and ECU calibration.

Most Cayenne owners have never heard of it.

I made a video explaining how it works and what parts Porsche included in the upgrade.

Would you install it on your Cayenne?

🚗 I Bought a Cheap Porsche Cayenne Turbo… and instantly regretted it.

At first it seemed like a bargain.

Then the problems started…

⚠️ Warning lights everywhere
⚠️ Suspension failure
⚠️ Scanner couldn’t even communicate with the car
⚠️ Hidden boost leaks
⚠️ Knock sensors buried under the intake

Every time I fixed one problem… another appeared.

What started as a cheap Porsche project turned into one of the most frustrating diagnostic puzzles I’ve ever tackled.

But the real causes were NOT what I expected.

I documented the entire journey in my latest video.

❓ Quick question

Would you buy a cheap salvage Porsche as a project car?

👍 Yes — worth the risk
😬 No — too many hidden problems

🔧 I built an engine… and then never drove the car.

Sounds stupid, right?

Months of work.
Careful assembly.
Perfect parts.

And then something happened that made me stop before the first real drive.

This video isn’t really about the car — it’s about a mistake almost every engineer (and car enthusiast) eventually makes.

👉 The project was finished… but the system wasn’t ready.

Have you ever completed a project and still didn’t trust it?

🚗 When a warning light appears…
Do you actually know what to do — or do you just hope it goes away?

Most drivers get this wrong.

I made a 10-question interactive challenge to see who would save their engine… and who would destroy it 😬

Can you score 8/10?

This build sparked an unexpected debate on LinkedIn…

Engineers were arguing whether this was:
• creative integration
• or a complete violation of good judgement 😄

The surprising part?

Adding a much more powerful engine didn’t really change how the car felt to drive — because the gearing dominated the behaviour.

It’s a perfect example of how systems behave differently from components.

Question for you:
What matters more in real-world performance — horsepower or gearing?

I finally made a video about one of my strangest projects.

It started as a simple restoration of a Mercedes coupe…
and somehow ended up with a Lexus V8 and Mustang bodywork.

I still don’t know what category it belongs in.

Question:
Would you have built it for acceleration or top speed?

🚗 Ever had a car lose power… but show ZERO fault codes?

I went down the full diagnostic rabbit hole:
• Forums
• Live data
• Sensors
• Expensive theories

Turned out the real problem was a tiny mechanical part…

💰 Cost to fix: $3

This is a perfect example of why understanding how a system works beats guessing and throwing parts at a problem.

What would YOU check first if a car jerks under acceleration with no codes?

This video has already triggered some great discussion in the comments — and I love seeing how differently people interpret Verification vs Validation depending on whether they come from software, hardware, aerospace, or automotive.

Most engineers can quote the definitions.
Far fewer agree on how they actually work in real projects.

If you’ve ever sat in a review thinking:

“We’re passing all the tests… but I’m not convinced this is right.”

This one’s for you.

💬 I’m especially curious:
Where do you see the biggest breakdown in your projects — requirements, testing, or real-world use?
