Continuing electrical issue

Hi

300tdi 97

Still having electrical issues

Disconnected battery was off for 2 weeks.

Reconnected it all leads correctly on battery checked and has been on charge all good.

Currently no electrics at all dash is dead central locking dead all lights external and internal dead.

Have completely removed battery and refitted to double check fused in engine bay all good.

Fuses under dashboard seem good there is on block connector no plugged into anything with 4 wires on it.

There is an immobiliser fitted but I have never had a fob for it and never needed it however this is the longest the battery has been disconnected for.

I am at a loss what to check next is the a fuse under the dash that I'm missing to check?

Any help or ideas greatfully received

Are any of the red led lights for immobilisor flashing when you lock/unlock the doors? There's a tiny led in the middle of either the dash binnicle or sometimes under the radio.

The second pic is an aftermarket immob set up. Do the lights flash on that?

No nothing on either

Are you getting power in the fuse boxes?

Not checked might be beyond my skills if I'm honest

Silly thing to say.

Have you checked that the battery connections are good? give them a wiggle and make sure they are clean and tight.

Cheers
