Renault Scenic II bj 2004 (diesel) Injection nozzle change, injection defective,repair

Hello dear ones, as a silent reader I have to ask a question today, because I have a big problem with my Renault Scenic II (JM) Built 2004 101ps diesel. I am now desperate to ask for a permanent workshop. I have now been in possession of this car for almost one and half years (kilometer number 140,000) and for a year the car spins like crazy. At first the blower engine was over, I had it installed for a whopping 900 euros. After some time the car suddenly showed error messages, first check injection, then injection defective. After the first change of a gland (mistake was again after several weeks), two months ago, the remaining ones would be replaced, except one that was still in great fire. After not once a month the same error came again, that the workshop told me that now the last injection nozzle caused problems. So the, the last Einspri tzdüse on this Wednesday. Now I had hoped that it was quiet with the car for the time being. However, it was today during the ride (after 20 km driving) that the car went out several times (without jerking). Then had to press the start button again and then the car jumped easily. On a turn the car indicated “STOP” and came back with the error message “Check injection / fail, this was about a second on the display and disappeared again. Meanwhile I’m really getting on my nerves, because the fun is not exactly cheap! And I have to say that since then I have never had such a car that had so many problems. I noticed that the car also likes to go out (not always) with a gyro. A week ago (we wanted to go on vacation) while on the way to the petrol station suddenly battery charge was defective or similar, also with a thick STOP and signal tone. This showed However, only one time and roof is not again. Maybe someone can help me or maybe already had the same problems with the car, because I slowly despair and regret this ever more chance and repertures to afford.
