Fault codes in BSI:

- Permanant fault. Absence of communication with the engine management ECU.
- Remote permanant fault. Coolant temp information. Incorrect value.
- Remote permanant fault. Vehicle longitudinal acceleration information. Incorrect value.

Fault codes in instrument panel:

Hi, welcome to the club.

Your English is very good - better than some English people..!

I suspect that the in-tank pump may have failed, you should hear it every time, even with a warm engine - it also has its own fuse.
Sometimes it can be persuaded to work by gently hitting the fuel tank with your hand.

PP2000, try scanning the engine ECU separately, select the ECU from the menu ( Bosch EDC15C I think.. ) and you may be able to access it this way.

Good luck, let us know how you get on.
