Hi, somebody maybe got problem with g20/30 with DDE MD1? 
My friend while driving the car G20 320xd, the message "drive carefully" was displayed and after a while car goes off. After read out the errors it appeared injectors fault with the description "needle closing sensor, injector from 1 to 4, break signal. According to ista, I checked the power supply for injection - correct. power supply was 3.11V, correct ground to injections, only after measuring the coil, resistance was slightly above the norm from 0.45 to 0.5 ohm. I gave the injections for verification but I guess that the DDE is damaged. I would like a hint, maybe someone had a similar problem. 
Errors from ista are 315800, 315A00, 315C00, 315D00. 

thanks for your help

Topic update. After a hard fight with the car, it turned out that after giving the injections for checking, it was found that they are seized and there are a lot of metal filings in the fuel, so the topic can be close. A little strange that at 100k mileage the injection pump ran out like in the F series
