Drallgate, injectors, ECU…

Hey Ihrs Meinem C70 D5 Bj 07 isn’t well… There’s already a mistake on the bus 1. No heating and no climate on the driver’s side. The other day I brought him to my screwdriver because of the already for a few weeks broken throttle. He called me the next day, three injectors went out, two are stuck.. he had to take him to a diesel specialist. Maybe besides the flap also the one or other injector would have to be changed. Couple days later call again, can the other two were tested and are still ok. The new ones were programmed and he is driving well, better than before. Everything would have been lost at the throttle valve, by the way. I was very happy and picked him up. On the second drive he suddenly ran restless. Error message in orange: ESP needs maintenance. Shortly afterwards in orange: transmission needs maintenance. Something later in red: engine maintenance DRINGEND. I let myself from the towing service from the Autob One of the two didn’t swap. Okay… then hold out the same old ones, replace them. Everything ok. Pick up. On the first ride after 5 km the same game… same error messages ESP, transmission, motor DRINGEND. I had to pick up from the screwdriver, he said, probably a mistake in the electronics… check out and get in information etc etc… wire harness? ECU?. Great… I calculated sc hon with having to export the moose for pocket money after I had already put so much money in and constantly new problems appear. Somehow enough, better an end with horror. The other day I was with the IT lunch with which I had built the Bluepower device. He meant that can almost not be… that gets broken where has been repaired.. there is probably only one plug not really in or cable broken or something stupid, problem of few cents un un un d Damage of a few thousand… Don’t you want to look for yourself? He is quite well equipped and a tinkerer.. now we look in there ourselves. And because of the error on the BUS 1 we also look. First we see if we can find a workshop manual of the C70 D5. Can someone help us there? What are your thoughts about the history? Did someone have similar problems?
