Good question!what is this test exactly testing and how do I use this test to check on the coils after the spark plug replacement I completed couple of weeks ago.
In Let's talk coil packs.. best brands / prices Jase says:
Unless you have an oscilloscope handy ... the resistance check won't net you a bad coil.
The low voltage used by typical multimeters when measuring resistance is not enough to properly test the secondary windings. See if your indy has a "megger" or, read up on using an O-scope (borrow) to test.
I ran the Bentley tests when I got a stumble / misfire on one coil pack. Primary resistance was "in spec" and gave me no info.
If it's new, maybe it is what you said. But also listen to see if it's the DISA.The car is running fine except for some tapping noise I heard when the car was warm

For plugs, one of these 'might' be for the V8:it is kind of hard to find 540 (V8) specific DIYs at times.

Also, the 740i E38 team often comes over here; sometimes paying 'them' a visit is worthwhile for their DIYs (which should be essentially similar).
