Moin together, I have a problem with my Peugeot Boxer (250 l, 2.2 HDI, 120 HP BJ 2010) & vlt. had someone here already experience with the same. Short to the background: I was on the highway, suddenly the temperature indicator jumps into the maximum, the red lamp lights up and the engine goes into the emergency run. I stopped, the hood opened; nothing. The engine was not exceptionally hot. Cooling water was warm and it was of course pressure on it. After I put the lid a little bit off Fgeschraubt & let everything cool down again. Engine jumped on without any problems, but the temperature indicator went directly back into the red area and emergency run was also inside. The ADAC then brought it to the next workshop. There the car did not start the next day at all. Only with start aid & full throttle it went on but then it also ran more than round. The temperature indicator also went directly up again and the fan jumped immediately. The control unit k They didn’t read out (Cold Soldering point?! I changed the battery the day before. Could a short circuit have been created?) We were then towed to a Peugeot workshop. They looked at this and said something about underpressure in the engine. The start problems could probably be due to defective injection nozzles (these are also wet at the edge) which to check and possibly replace would cost a lot. Especially after that one would not know if the problem would be solved u And it could be that you have to take the engine completely apart. In the end, I was told by the flower that this was an economic total damage. The car was always running perfectly with the mileage of 346,000 km. Oil changes etc. were always made. Now my question: Has anyone ever had experience with similar problems? If so, what was it in the end? Should one repair the control unit first? Would a replacement engine be more worthwhile? The bodywork is top in shot. If someone is on the road in the Bremen room and knows about PN. Thank you in advance.
