my brother Carsten is on his way to the well-deserved holiday with his A8. 4,2 l, year '95.
One cylinder is out of order. Lt. ADAC is the compression but good and the ignition coil is also i. O. Only the ignition coil of the 4. Cylinders don't get Siganl. Lt. ADAC is an event. the final stage of ignition deffekt. The fault memory was read out at Audi... Result: no current on the ignition coil of the 4. Cylinders. Lt. Audi costs the control unit 1140,- plus. Wage.
Just to the question: Does anyone know if the power stages for each cylinder are to be individually installed and externally installed by the control unit? If someone has had this mistake himself, he can do something about it. Say fix?
I hope I've recorded everything correctly for my brother, because I'm not a car professional...

Everything went just by phone from Croatia.
If there are any questions, I will try to clarify them.
Thank you for your help
Frank
