How i Can Check The Coil.

Thx Torsten

 

Don't bother, change the CTS sensor. The CTS can cause everything from a hard start to miss-firing the engine without throwing a CEL. Its cheap and easy to do.

 

Thx Auditech79,

I Will Try This Tommorw.

When i Drive Like This Can I Damage my Car?
Wher is A Good Place To buy Parte For audi .


Thx Torsten

 

You can drive it fine, the engine really isn't miss-firing, the faulty signals from the CTS is fooling the engine management into thinking there is a miss so it kinda stumbles a little bit.

 

Audozone and Advance auto parts don,t have the cts Sensor

thx torsten
