Nice job and what a cracking video. Not so common to find corroded fuses and sometimes not possible to see this resistance with the naked eye. Hell of a drop there 👍
This is fuse 7 in the engine compartment fuse box (next to the pcm). This one fuse feeds a lot of components. Inlet cam solenoid, oil pressure control valve, coolant pump relay, canister purge solenoid, turbo pressure control and bypass valves. It feeds the red/yellow wire to each of these components.
The car was a 2012 Audi A4 1.8TFSI. The fuse was number 6 (15A) in the left plenum chamber (next to engine ECU). This powered the engine component supply relay coil and three of the fuses in fuse panel c (at the side of the dashboard). The three fuses where for clutch pedal switch interlock (5A), fuel pump control module (25A) and brake light switch (5A). I used the free wiring diagram CARMIN STD in the app store to find it.
Nice work. Very helpful.

Thank you. It definitely was an unusual fault. Proof that checking for voltage drop is a great diagnostic test. 😊
Excellent presentation of a simple method of narrowing down the problem... Saving!
Glad you liked it, many thanks.
Thank you for the well explained process. What was this fuse operating please?

Could you do another one. This time with a buried faulty cable power or earth?
nice job thank you for sharing
I have questions what is the car and what is consumer connector was ?

easy way&greatlly diagnostic job.thank y for yr explanation.
You are very welcome.
Fantastic explanation but this is why I teach my apprentices to use test lights on fuses.
Absolutely. The test lamp is still one of the fundamental pieces of diagnostic equipment that should be used when checking circuits.
Thanks for video
You are welcome 😊
