Technical '06 Panda crank sensor issue.....

The good news is the earlier error code

Confirms we have a power ground issue

It's telling us the body computer. Received less than 8.5V difference between the ground and positive

Which means all the immobilizer errors and so on are because of this

Possible locations to look for?
 
There's quite a few

But first I was seeing if the battery was okay and the voltage to the ECU was okay with the live data

But the results are not as expected and not the same as posted earlier
 
First job is to swap the body computer relay over for a different one

Check the pins for corrosion

Clear the codes and see what happens

These would be good to swap

These are the 4 relays in order you know from the different one

Checked them again all good using a 12v tester and a pair of wires they are functional all of them
 
The relays numbers based on the cover is T09,T08,T31 and T20 those you mentioned from the top down
 
They are mentioning an issue with the antenna ring took it out and measured the resistance, it's 30 ohms or 32 it was i don't quite remember and still if i go with the scan tool over to the live data i get an allowed to start
 
I swapped them as you put on the picture you edited and still no start tried to run a diagnostic but laptop died charging it now
 
Here in this image last row if you can see recognized

Let's not get side tracked, scan tools aren't 100%

But the data we have is low voltage at the BCM which is causing the immobilizer data not to be transmitted

If the antenna is faulty the immobilizer light does not go out
