Hello and moin moin, Have currently a problem with a reverberator. Vehicle: Audi 100 V6 2,6L 150PS BJ.93 So now to the problem: The Audi does not start. No ignition spark. Have read out the error memory: reverberator no signal The power supply is usually just like the ground line And the funny thing is the control unit 9V on the signal line! I thought maybe a Maderbiss. Have measured the cables it is all in order. Did then the directly measured on the control unit (cable tree deducted) DIRECTly on the pin of the signal line lie also 9v. Usually I shoot through with a voltage on the signal line every reverber. Is this car an exception? Have the control device already exchanged there is exactly the same “error” present?! Has anyone ever had the same error of you ? MFGG
