Electronics problem with ignition off.

Hello together, I have a problem there. My fat guy has a mistake in the electronics. When I turn off the ignition, the engine (2.2 tdci 140PS Bj2010) continues to run until I step on the brake, then he goes out, but then the airbag control lights, the indicator lights at the switch of the front and rear disc heating and the control servo from the turbocharger beeps go through and tries apparently constantly to regulate even when the car is off and locked up. Before that, after the batteries were both empty, they were removed and recharged again in the warm basement. After the re-anklemen, the immobilizer didn’t go out for the first time and flashed quickly. Only once I had stepped on the brake the immobilizer went out and the thickness jumped on. If it runs there is no mistake. I have no approach to what might be lying down. When the error is read out comes out a ellenlange list. Has anyone had a similar problem?
