No voltage at Coil on 5KTQ

[Richard Sargent]

Joel,

You have described exactly what happened to me when the ignition switch (the plastic part) in one of my Audis finally cracked from the constant pressure of the return spring. I'm sure a new switch will fix your problem.

(When I replaced mine, the lock portion fell to pieces as I was removing it, and I ended up using one from a parts car. Now that car has 3 keys. One for the doors, another for the ignition, and a third for the locking gas cap. It even needs yet another key, since the key I received when I bought the car appears to be a valet key, and I cannot open the trunk or the glove compartment! I'm not concerned about re-keying the locks at the moment, since I'm waiting for the last (!) door handle to break before I replace them all, and re-key the locks at the same time. I'm now on my 6th Audi, and have collected dozens of Audi lock cylinders over the years.)

Hope that helps,

Richard.

>Had a no start condition today on one of my Audi 5KTQ.

>Traced the lack of spark to no voltage at BL/R wire on coil.  My Bentley wire diagram shows that this comes from the ignition switch. 
>To get home, I ran a hot lead from the 12volt charging lug to the second spade connector on the right side of the coil.  Ran fine. 

>I've several bad ignition switches over the years, but never a failure of this main lead to the coil.  
>Any other "BTDT" experiences you can share, before I R & R the ignition switch?
