PLEASE READ! PROBLEMS WITH MK7 CABRIO AT STARTING

Hello people have the following problem: if I want to start my mk7, the ignition goes on but if I continue turning to start the motor does not do anything he gurgles not even! the led under the clock should actually light up when starting for 2-3 sec. but if the problem is there she doesn’t do it. the problem is also net always there but only occasionally, but on the car there is no longer any reason. I have tried it with a push, but he doesn’t go there either, the reason why but the problem is still there. I thought it was the immobilizer, right???? because it goes with pushing also net???? the car usually starts at me in front of the door of the house, but if I happen somewhere else it always happens that the motor net starts. has had such a problem before???? would be happy to answer a few questions. mfg alex from ffm.
