Hi, I have a 2003 S80 2.5T.

I was going to read the codes with my Autel tablet, the battery ran out (bad battery). Now it won't start anymore, put in another battery, tried with a booster first.

But nothing happens, I hear a click from a relay but nothing else.

The electronics are also completely messed up, ghost messages and so on. Start interruption warning.

The car worked before, I've never experienced this while reading the codes before.

I wanted to read the codes in connection with P0101. Think vacuum leak at the vacuum lines towards the turbo. But not sure yet...
