How to Test VW Audi Ignition Coils 

👍

I have a preamplifier for that. Yes, if you tap to the trigger wire it will load the signal. But, with the RPM pre-amp you'll be fine. We do lots of custom electronic work, I will sent you a Paypal invoice if you want the Pre-Amp. The cost is $355.00. and it's wires are all labeled. Suggest you call me if you want.

José, this is not possible, to check with a multimeter. The issue is that the driver transistor is built inside the coil itself, like most newer coils. That's why we created our low cost VW Audi coil testers seen here... www.autodiagnosticsandpublishing.com/VW_Audi_COP_Coil_Tester_Pulser.html

Good, thanks

No, Ohming coil isn't productive. Lands to skewed results.

It's all in the the ECM software.

@@ADPTraining in the what?

VW Audi Coils have two grounds. Probably one for the Coil and other for the trigger transistor. autodiagnosticsandpublishing.com/

@@ADPTraining ,thank you for your reply. some vehicles only have three leads with only one ground, they still work.

Sure, how it's wired internally is not important, just that you have 1 or 2 grounds.

Absolutely, but it might not be the correct l though. Thanks for posting, see my Ebooks here. www.autodiagnosticsandpublishing.com/Automotive_Diagnostic_Repair_Book_Catalog.htm

Resistance us not a viable test.

No, yes the VW Audi COP coils are 4 leads, but on my diagram it's 3 that's because it has 2 grounds. I didn't showed it on the diagram for simplicity. It's not a mistake.

Trigger voltage. See my other videos.

That is the state of the American way if thinking. We're becoming dumbmmer by the minute.

@@ADPTraining ANYONE that has been around long enough to know how things on cars worked one time not so long ago knows what these ASS H.... that make there cars have done to people so they can't fix their own cars OR do ANY work on them, knows ALL THIS CRAP is set up to ROB their loyal customers BLIND and people like you are to STUPID to know it or say anything about it.

If you were to build a new vehicle the old fashioned way, it would weight an extra 3000 lbs. Things are the way they are because they have to, not because they want to. Could we have made a Tesla 10 years before, yes. 20 years before, no. Brushless motors with strong magnets were not practical yet. 30 years ago, forget it. Technology continues to advance. Is 5G meant to kill people, no, even though it looks that way. What you should ask is, why wasn't a Tesla like technology developed 30 years ago. The answer is, due to powerful oil industry interests. I understand your fears, some are real, but not all of it.

this isn't much more complicated than the old Sears all in one testers that checked voltage regs, batteries, ignition coils, advance/dwell, etc
