[Solved] VW LT 28 - The indicator light from the immobilizer flashes, it does not start o

Hello
I have a problem with the Volkswagen LT. The car is from 2002, engine 2.5TDI. From the beginning, practically, from the purchase, we have a problem with the blinking immobilizer indicator. Orange light https://static.elektroda.pl/attach/20150714_123025_7b16690.jpg

We have been traveling with her for over a year. There has been a problem recently. The car sometimes doesn't want to light up for anything, there are no lights. It even takes 15 minutes, then suddenly it lights up and everything is OK.

The control cannot be deleted by Vaga, we tried to delete the error.

I am asking for a hint what could be the problem?

There are no lights? That is, after turning on the ignition, no reaction on the meter? As for Immo, I would check the coil on the ignition switch.

Yes there are no controls. The coil on the ignition switch, i.e. the ignition switch? Is it something else?

If it does not turn on the controls, the ignition block may be to blame. As for the immo, you have a black ring around the ignition switch and this is the immo coil

Hello
The cube of the ignition switch was replaced with a new one, the coil was supposed to be operational (I bought a new one). Surprisingly, the light has stopped flashing, I hope that there will also be no problems with starting it. Thank you for your help
