result...
here are the readings that i got from the coil
3-5=12.86
2-4=12.05
1-6=11.84
good?bed?fugly?
its almost 2am and i'm going to sleep...
what the hell is wrong with this stupid caR?!
p.s. just remembered something, i do not have a vacuum tank, i have the line caped off. dose that make a huge difference?

post just disapered....
ok, there were like 3 posts here that just vanished... wtf?
tested resistance in the coil
3-5=12.86
2-4=12.05
1-6=11.84
good? bed? ugly?
p.s. i just remembered something, i'm lacking a vacuum tank and i have that line caped off, will that make a difference?

rather than edit his post the person that recommended testing by water deleted his post...
that in turn simultaneously deletes ALL responses to his post. That of course deleted the Bentley procedure for testing coils and primary resistance I posted for you.
Basically you're good coil-wise as the Bentley spec is that each coil must register resistance between 9 and 14k Ohms at each coil which you've now done.
The other test I mentioned in that post is one that moribundman mentioned below and has to do with the "primary resistance" between the coils and the POS (power output stage) and involves testing the 3-wire harness that runs from the POS to the coils. Those leads should show resistance between .5-1.0 Ohms. If out of range either way that 3-wire harness lead should be replaced or you risk a similar failure to what moribundman experienced below. Test is simple and only involves using a multimeter at opposite ends of terminal #1, 2 and 3 for resistance.

You can however dig up response posts by finding the post number...
Here is the procedure for future reference:<ul><li><a href="https://forums.audiworld.com/12v/msgs/73162.phtml">https://forums.audiworld.com/12v/msgs/73162.phtml</a</li></ul>

that still just sounds bed...
ok, i work for a VW dealer as a parts consultant. I HAVE NOT HEARD OF ANYONE <b>ever</b> spraying water on a coil.

hey VAP...
so here is what i got.
from upper to lower terminal...
4.02
0.66
0.72
my coil is on its way out the door???
also i was wondering if this coil would work?
