Hello first of all. I have been driving the Omega 2.5 DTI year 2002, 127000 km for about 1 year. For some time it always comes before that it does not start. Then I have to switch off the ignition, keys out and after two minutes it starts as if nothing had been. For a few weeks he is in a state of total rest and when I go it is gone and as soon as I stand there again. In the error memory the following errors were: Problems with pre-glowing too low rail pressure at engine start pre-shipment pressure too low So off to the FOH… Diesel filter swapped, incandescent pins swapped, broken diesel line swapped –> Mistake away car starts up and in the stand still restless. Five days later the self shit and it doesn’t start. And again to the dealer and Him asked what it could be. The answer was I don’t know, let the car as we look. But I can’t tell you how long it takes and what it costs… What a statement. So I’m going to do the thing myself now. Take it in my hand. I wanted to start with the relay and then see if the error occurs again with the jump-in. After that test backflow quantity to find out if an injector is possibly there ( due to restlessness in the stand). What do you think it might still be. VFP broken or maybe the 20 l problem? Please urgently for help. Thank you in advance Slutrossi
