Hello, a few questions for the technicians among us: I have heard that the petrol pump is not constantly in operation – question: is that correct ? What happens if the petrol pump is shut down and stays off while driving ? (e.g. if the ground line is interrupted to the ground connection point under the rear seat (in the W220) ). I am interested in this because such a relatively simple anti-theft protection would be possible – but would like to assume that then any steering gear would be used. Save the error messages… Could you also prevent the car from starting? Greetings
