Rugging and high consumption at our V50 2.0D with 180000

Hello guys, we have problems with our V50 again. It is a 2.0D and has a little over 180000 on the speedometer. I briefly describe the procedure of things. It started with increased consumption- Currently we are at about 8L/100Km. We were at the Free Workshop, no diagnosis, no error with the universal device indicated. Well, continued. Then a slight jerking in the lower speed range was added. We then drove further up in the display of the error “Motorsystem maintenance e The reason for this was that the workshop did not have an appointment in the next few weeks and only deleted the error. I then tried to find a bug myself. So I bought and set up a Vida Dice on Ebay. My first guess was that the DPF did not make any more regeneration. The DPF was not changed at 120000, only professionally cleaned. So the first thing I did was that the DPF was not replaced at 120000. e I read the last cycle from the regeneration, this showed at 2,5km. I started from a permanent regeneration, therefore also the high consumption. So the filling of the additive tank read out – 1/15, LEER. Then got me a liter of Eoys 176 and replenished the additive tank. About Vida then reset. Read out 15/15. Super I thought it would be, the additive will be replenished at the next refueling, regeneration and good. At the first refueling I am at risk with the Vida. n to see if the pump is running after refueling. Unfortunately, the pump did not run. However, I don’t get any error from the ADM. The pump is not running again via the function of filling the additive hose after repair. How would you like to continue? My wife usually moves the Volvo, this morning the message “motor system maintenance is required” came again at the speed ranges 1200 and 2300 when there was a strong jerking. I will read out the message again this evening. About jeg I would be very happy if I could give you tips! Thank you very much in advance! -so long
