Thanks to all for the good tips. Today i have another session with the Opel...
Now I am back an at first I have to tell the story:
I phone the other shop and ask about the exact history of the car. They say that the car has misfire on various cylinders. They read the codes: "anything with camshaft sensor". They change the sensor. After that the misfire was still present. Now they change the Ignition-Coil (Trial and Error
). With the Ignition Coil they change also the ignition cable. It is a bundle to buy.
Then the misfire was still not eliminated!!
At this point, the car came to me. Yesterday i made all the oscilloscope recordings.
Cause of the reply of Fat Freddy, i read the error memory once again: No errors.
Then i control the timing belt once again - no error.
After that i look at the oscilloscope recordings from yesterday. I notice something in the recording "Opel_Astra_2004_Petrol_Injektor_Ignition.psdata" (It is much longer than "Opel_Astra_2004_Petrol_Injektor_Ignition_klein.psdata". There is occasionally after the switch off the Ignition Circuit "green" a number of inductive interference in circuit "brown".
Where are they come from and maybe the interferences have a retroactive effect on the ecu?? Maybe they come from the output stage within the ignitioncoil-pack. I took the old ignitioncoil from the trunk.
After the change from new coil to old coil the motor is running perfect! The new ignition coil is faulty!
But why is the car now running? The misfire doesn´t come from the camshaft-Sensor and doesn´t come from the old ignition-coil! The old ignition-cables were broken. They had very small marten bite
Many hours and a lot of money because such a simple thing!!! The effect off "trial and error"!
Unfortunately there was no time left to hook up the pico once again for a "known good" signal.
Many many thanks for the quick response - it helps me to find the error!
