DEF System Case Study: BMW X5 Diesel - Part 1

Did you miss THE BEARD?? This case study is from a few months ago, and took a while to edit...

We jump in the deep end with this diagnosis: It's Euro, it's a BMW, and it's a Diesel! And we're dealing with a fault in the Diesel Exhaust Fluid system, with only basic technical information available!

This is an example of how we can use basic principles to reverse-engineer a system, figure out how it functions, and finally make a 100% definitive diagnosis. Of course, this process takes time. Some might call it "excessive overthinking" and an "unnecessary waste of time"....

Personally, I see it as quality time in the science lab, where you can get first-hand experience and acquire more knowledge in one hour, than weeks of lectures in a technical school or formal training.

In any case, when the suspected faulty part costs over $2,000, it is worthwhile to dig a little deeper.

Take some notes and as always, Enjoy! I promise Part 2 will be a bit more exciting :)
