Car’s running out of gas.

Hello, I’m desperate. Yesterday I got my car out of the workshop. No mistake could be found. The car is a Citroen C5 HDI 2.2 with 133 hp. In the workshop I was told that the car would drive only 140 km and they could not find the reason. They hung on it for 8 hours at a time. Today I drove by car, just before the traffic lights went on again the service went on and the ABS fell off. Then had to stop at the traffic light at Red. I tried to start it again 4 times, but again and again the same thing. As soon as I turned from P to D and gave off gas, he went out immediately again. After 15 minutes with warning flashing light at the intersection, he let himself start again and also drove. The service lamp is still on, but the warning for ASB failure is off. I have to say that I am severely disabled and driving hand gas on the left hand A side for which I have a special permit from Marburg. Until now: turbocharger, AGR valve, air mass meter and cat. The circus started so properly as the return hose to the left of the shock absorber crack. Since then the car has been in the workshop 5 times. At first it still drove and it just went on the service lamp and the ABS fell off. Then the car went into the emergency run. When I turned off the car and the lamp for ABS failure was off, the car also pulled out again. Everything gets worse and worse. I can’t afford a new car. Only installing hand gas costs 5,900 euros plus additional costs and I don’t have a car yet. Who knows advice or has ever heard of something like this? I’m receptive to any advice.
